Question: when did they start using daylight savings time

Answer: April 30 , 1916

This is a document about Daylight saving time
 in 1895. The German Empire and Austria-Hungary organized the first nationwide implementation, starting on April 30, 1916. Many countries have used it at various times since then, particularly since the energy crisis of the 1970s. DST is generally not observed near the equator, where sunrise times do not vary enough to justify it. Some countries observe it only in some regions; for example, southern Brazil observes it while equatorial Brazil does not. Only a minority of the world's population uses DST, because Asia and Africa generally do not observe it. DST clock shifts sometimes complicate timekeeping and can disrupt travel,

This is a document about Daylight Saving Act of 1917
  The Daylight Saving Act of 1917 was enacted by the Dominion of Newfoundland to adopt daylight saving time (DST), thus making it one of the first jurisdictions in North America to do so, only a year after the United Kingdom on May 21, 1916. DST was not instituted in the United States until March 31, 1918.

This is a document about Time zone
  Many countries, and sometimes just certain regions of countries, adopt daylight saving time (DST), also known as summer time, during part of the year. This typically involves advancing clocks by an hour near the start of spring and adjusting back in autumn ("spring forward", "fall back"). Modern DST was first proposed in 1907 and was in widespread use in 1916 as a wartime measure aimed at conserving coal. Despite controversy, many countries have used it off and on since then; details vary by location and change occasionally. Countries around the equator usually do not observe daylight saving time, since the seasonal difference in sunlight there is minimal.

This is a document about April 1966
 U.S. President Lyndon Johnson signed the 1966 Uniform Time Act, setting a common date (the last Sunday in April) for all states in the U.S. to set their clocks forward one hour, beginning on April 29, 1967, and to set clocks forward one hour on the last Sunday in October, starting in 1967. At the time, 18 states observed daylight saving time (DST), 14 switched time zones rather than changing their clocks, and the other 18 left the option up to their local governments.  Before the Uniform Act was passed, the prescribed days for changing the clocks varied across the nation; in the state of Iowa alone, there were

This is a document about Time in Spain
  Daylight saving time (DST) was first introduced in 1918, the year in which World War I ended. It was then introduced and abolished several times. It was not applied in 1920–1923, 1925, 1930 nor during the Second Spanish Republic period in 1931–1936. During the Spanish Civil War, DST was re-established, but there were different dates of application, depending on if the territory was under the control of the Republican faction or Nationalist faction. Curiously, the Republican faction made its first attempt to change from Greenwich Mean Time to Central European Time when time was advanced 1 hour on 2 April 1938 and advanced another hour on 30

This is a document about Daylight saving time in the United States
  During World War I, in an effort to conserve fuel, Germany began observing DST on May 1, 1916. The rest of Europe soon followed. The plan was not adopted in the United States until the Standard Time Act of March 19, 1918, which confirmed the existing standard time zone system and set summer DST to begin on March 31, 1918 (reverting October 27). The idea was unpopular, especially with farmers because DST meant they had less time in the morning to get their milk and harvested crops to market. Congress abolished DST after the war, overriding President Woodrow Wilson's veto. DST became a local option. New York City continued to observe a metropolitan DST, while rural

This is a document about Sunshine Protection Act
  Time zones were first introduced in the United States in 1883 by railroad companies. In 1918, they were codified into federal law by the Standard Time Act, which also included a provision for nationwide daylight saving time modeled after European laws designed to save energy during World War I, but that component was repealed a year later due to protests by farmers. Many states subsequently introduced daylight saving time, and in 1966, the Uniform Time Act standardized the dates when it begins and ends. Hawaii, most of Arizona, and the U.S. territories have opted to observe permanent standard time, but the Uniform Time Act forbids observation of permanent daylight saving time. Researchers have observed numerous ill effects of the annual transitions between daylight saving time and standard time. These include reduced worker productivity, increased heart attacks and strokes, and increased traffic incidents. Researchers have also observed ill effects of standard time compared to daylight saving time, including increased crime, more frequent traffic incidents, increased prevalence of seasonal depression, and greater energy usage. In the late 2010s, resolutions were passed in more than 30 states advocating for the federal government to abolish the annual transitions.

In 1907, British resident William Willett presented the idea as a way to save energy. Despite receiving some serious consideration, it was never implemented. In 1908 Port Arthur, Ontario, Canada started using DST. Starting on April 30, 1916, the German Empire and Austria-Hungary each organized the first nationwide implementation in their jurisdictions. Many countries have used DST at various times since then, particularly since the 1970s energy crisis.

  30, 1916, as a way to conserve coal during wartime. Britain, most of its allies, and many European neutrals soon followed. Russia and a few other countries waited until the next year, and the United States adopted daylight saving in 1918. Most jurisdictions abandoned DST in the years after the war ended in 1918, with exceptions including Canada, the United Kingdom, France, Ireland, and the United States. It became common during World War II (some countries adopted double summer time), and was widely adopted in America and Europe from the 1970s as a result of the 1970s energy crisis. Since then, the world has seen many enactments, adjustments, and repeals.

Daylight saving time was repealed in 1919, but standard time in time zones remained in law, with the Interstate Commerce Commission (ICC) having the authority over time zone boundaries. Daylight time became a local matter. It was re-established nationally early in World War II, and was continuously observed until the end of the war. After the war its use varied among states and localities. The Uniform Time Act of 1966 provided standardization in the dates of beginning and end of daylight

Major American observatories, including the Allegheny Observatory, the United States Naval Observatory, the Harvard College Observatory, and the Yale University Observatory, agreed to provide telegraphic time signals at noon Eastern Time. Standard time was not enacted into US law until the 1918 Standard Time Act established standard time in time zones; the law also instituted daylight saving time (DST). The daylight saving time portion of the law was repealed in 1919 over a presidential veto, but was reestablished nationally during World War II. In 2007 the US enacted a federal law formalizing the

This is a document about Eastern Time Zone
  For those in the United States, daylight saving time for the Eastern Time Zone was introduced by the Uniform Time Act of 1966, which specified that daylight saving time would run from the last Sunday of April until the last Sunday in October. The act was amended to make the first Sunday in April the beginning of daylight saving time beginning in 1987. Later, the Energy Policy Act of 2005 extended daylight saving time in the United States, beginning in 2007. Since then, local times change at 2:00 a.m. EST to 3:00 a.m. EDT on the second Sunday in March, and return from 2:00 a.m. EDT to 1:00 a.m. EST on the first Sunday in November. In Canada, daylight saving time begins and ends on the same days and at the same times as it does in the United States.

This is a document about Time in Germany
  Daylight saving time was first introduced during World War I by the German Empire in the years 1916 to 1918. After the end of the war and the proclamation of the Weimar Republic in November 1918, daylight saving time ceased to be observed. It was used again 1940–1949 (from 1945 differently in the West and East) and introduced again from 1980. West and East Germany had the same time and DST from 1950 until unification. In 1996, daylight saving time was harmonised throughout the European Union by Directive 2000/84/EC, which moved the end of DST to the last Sunday in October. In 1980 the exclave Büsingen did not use DST in order to keep to the same time as Switzerland.

The political equation changed in other countries; the United Kingdom used DST first on May 21, 1916. US retailing and manufacturing interests—led by Pittsburgh industrialist Robert Garland—soon began lobbying for DST, but railroads opposed the idea. The USA's 1917 entry into the war overcame objections, and DST started in 1918. The end of World War I brought change in DST use. Farmers continued to dislike DST, and many countries repealed

 Under federal law, daylight saving time went into effect throughout the United States for the first time, with the 1966 Uniform Time Act mandating that clocks be set ahead one hour at 2:00 in the morning on the last Sunday in April and then turned back one hour on the last Sunday in October. However, the law provided that any state could seek exemption from compliance by the United States Department of Transportation, and five of the 50 states chose to effectively change time zones rather than to change their clocks.

The practice was stopped after the war, but resumed 12 years later, in 1957. Egypt normally observed daylight saving time between the last Friday in April and the last Thursday in September when the clocks were three hours ahead of Greenwich Mean Time (UTC+3). The change occurred one second after 23:59:59 on Thursday to become 1:00:00 on the last Friday in April shortening the day to 23 hours.

The Daylight Saving Time Act of 1966 set a uniform date for all states in the US to begin and end daylight saving time on the last Sunday in April and the last Sunday in October, respectively.


Question: which technique measures the electrical activity of brain cells directly

Answer: Electroencephalography ( EEG )

This is a document about Electroencephalography
 Electroencephalography Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used such as in electrocorticography. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain. In clinical contexts, EEG refers to the recording of the brain's spontaneous electrical activity over a period of time, as recorded from multiple electrodes placed on the scalp. Diagnostic applications generally focus either on event-related potentials or on the spectral content of EEG. The former investigates potential fluctuations time locked

 as a complete, unbiased attention to the current moment. Electroencephalography (EEG) has been used in many studies as a primary method for evaluating the meditating brain. Electroencephalography uses electrical leads placed all over the scalp to measure the collective electrical activity of the cerebral cortex. Specifically, EEG measures the electric fields of large groups of neurons. EEG has the benefit of excellent temporal resolution and is able to measure aggregate activity of portions or the entire cortex down to the millisecond scale. Unlike other imaging based methods, EEG does not have good spatial resolution and is more appropriately used to

This is a document about Brain fingerprinting
 Brain fingerprinting Brain fingerprinting is a lie detection technique which uses electroencephalography (EEG) to determine whether specific information is stored in a subject's brain. The technique consists of measuring and recording a person's electrical brainwaves and brain response when asked questions about a crime, attempting to elicit a "P300 response" that indicates familiarity with the details of the crime. The technique is controversial, unproven and of questionable accuracy. Comparison of brain fingerprinting with polygraphy showed mixed results consistent with "a mix of proven techniques and dangerously exaggerated benefits". Brain fingerprinting was invented by Dr. Lawrence Farwell. In 2001, the technique

The 1980s, with the introduction of inexpensive computers, opened up a new door for cognitive neuroscience research. Currently, ERP is one of the most widely used methods in cognitive neuroscience research to study the physiological correlates of sensory, perceptual and cognitive activity associated with processing information. ERPs can be reliably measured using electroencephalography (EEG), a procedure that measures electrical activity of the brain over time using electrodes placed on the scalp. The EEG reflects thousands of simultaneously ongoing brain processes. This

 'brainwaves' in common parlance. The technique of recording neural electrical activity within the brain from electrochemical readings taken from the scalp originated with the experiments of Richard Caton in 1875, whose findings were developed into electroencephalography (EEG) by Hans Berger in the late 1920s. The functional role of neural oscillations is still not fully understood; however they have been shown to correlate with emotional responses, motor control, and a number of cognitive functions including information transfer, perception, and memory. Specifically, neural oscillations, in particular theta activity, are extensively linked to memory function, and coupling between theta and gamma activity is

This is a document about Neurotechnology
  Electroencephalography (EEG) is a method of measuring brainwave activity non-invasively. A number of electrodes are placed around the head and scalp and electrical signals are measured. Clinically, EEGs are used to study epilepsy as well as stroke and tumor presence in the brain. Electrocorticography (ECoG) relies on similar principles but requires invasive implantation of electrodes on the brain's surface to measure local field potentials or action potentials more sensitively. Magnetoencephalography (MEG) is another method of measuring activity in the brain by measuring the magnetic fields that arise from electrical currents in the brain. The benefit to using MEG instead of EEG is that these fields are highly localized and give rise to better understanding of

This is a document about Neurophysics
  Old techniques to record brain activity using physical phenomena are already widespread in research and medicine. Electroencephalography (EEG) uses electrophysiology to measure electrical activity within the brain. This technique, with which Hans Berger first recorded brain electrical activity on a human in 1924, is non-invasive and uses electrodes placed on the scalp of the patient to record brain activity. Based on the same principle, electrocorticography (ECoG) requires a craniotomy to record electrical activity directly on the cerebral cortex. In the recent decades, physicists have come up with technologies and devices to image the brain and the its activity. The Functional Magnetic Resonance Imaging (fMRI) technique, discovered by Seiji Ogawa in 1990, reveals blood flow changes inside the brain. Based on

  Techniques such as large scale single-cell recordings are movements in the direction of analyzing overall brain rhythms. However, these require invasive procedures, such as tetrode implantation, which does not allow a healthy brain to be studied.

  A classic and popular tool used to relate mental and neural activity is the electroencephalogram (EEG), a technique using amplified electrodes on a person's scalp to measure voltage changes in different parts of the brain. Hans Berger, the first researcher to use EEG on an unopened skull, quickly found that brains exhibit signature "brain waves": electric oscillations which correspond to different states of consciousness. Researchers subsequently refined statistical methods for synthesizing the electrode data, and identified unique brain wave patterns such as the delta wave observed during non-REM sleep. Newer functional neuroimaging techniques include functional magnetic resonance imaging and positron emission tomography, both of which track the flow of blood through

This is a document about Translational neuroscience
  Electrophysiology is used within translational neuroscience as a means of studying the electric properties of neurons in animal models as well as to investigate the properties of human neurological dysfunction. Techniques used in animal models, such as patch-clamp recordings, have been used to investigate how neurons respond to pharmacological agents. Electroencephalography (EEG) and magnetoencephalography (MEG) are both used to measure electrical activity in the human brain, and can be used in clinical settings to localize the source of neurological dysfunction in conditions such as epilepsy, and can also be used in a research setting to investigate the differences in electrical activity in the brain between normal and neurologically dysfunctional individuals.

This is a document about Alcohol-related brain damage
  While the hemo-dynamic methods are effective for observing spatial and chemical changes, they cannot show the time course of these changes. Electromagnetic imaging methods are capable of capturing real-time changes in the brain's electrical currents. Electroencephalography (EEG) imaging utilizes small electrodes that are attached to the scalp. The recordings are averaged by a technique known as event-related potentials (ERP). This is done to determine the time sequence of activity after being exposed to a stimulus, such as a word or image. Magnetoencephalography (MEG) is another imaging method that utilizes sensors. This measures the magnetic field created as a result of the brain's electrical activity. These techniques are noninvasive, harmless, and provide a large amount of detail regarding the order and timing of electrical activity. The poor spatial imaging of these methods are a large downside. These neuroimaging methods have found that alcohol alters the nervous system on multiple levels. This includes impairment of lower order brainstem functions and higher order functioning, such as problem solving. These methods have also shown differences in electrical brain activity and responsiveness when comparing alcohol-dependent and healthy individuals.

  Bioelectromagnetics refers to the ability to study live cells, tissues, and organisms that produce electromagnetic fields. Bioelectromagnetism is mostly studied via electrophysiological techniques. Some of the electrophysiological monitoring methods such as electroencephalography (EEG) and electrocardiography (ECG or EKG) measure the electrical activity of the brain and heart via the installation of electrodes placed on the skin. Recorded evoked potential (EP) amplitudes tend to be low, ranging from tens of microvolts for EEG, millivolts for electromyography (EMG), and about 20 millivolts for ECG. Other electrophysiological monitoring techniques such as evoked spinal cord potential (ESCP), somatosensory evoked potential (SEP) and SSEP (short-latency SEP) could be coupled with ECG, which then present excitatory ECG-triggered SSEP

Answer: Schwann cells

This is a document about Myelin
 Myelin Myelin is a lipid-rich (fatty) substance formed in the central nervous system (CNS) by glial cells called oligodendrocytes, and in the peripheral nervous system (PNS) by Schwann cells. Myelin insulates nerve cell axons to increase the speed at which information (encoded as an electrical signal) travels from one nerve cell body to another (as in the CNS) or, for example, from a nerve cell body to a muscle (as in the PNS). The myelinated axon can be likened to an electrical wire (the axon) with insulating material (myelin) around it. However, unlike the plastic covering on an electrical wire,

 Vestibular schwannoma A vestibular schwannoma (VS) is a benign primary intracranial tumor of the myelin-forming cells of the vestibulocochlear nerve (8th cranial nerve). A type of schwannoma, this tumor arises from the Schwann cells responsible for the myelin sheath that helps keep peripheral nerves insulated. Although it is also called an acoustic neuroma, this a misnomer for two reasons. First, the tumor usually arises from the vestibular division of the vestibulocochlear nerve, rather than the cochlear division. Second, it is derived from the Schwann cells of the associated nerve, rather than the actual neurons (neuromas). Approximately 2,000 to 3,000 cases
