EEG Uses. Doctors use this test to diagnose epilepsy and other brain conditions, brain injuries, and sleep disorders.Seizures cause spikes on the EEG graph. Brain tumors or a stroke make the waves ...

The various types of brain wave on an EEG have different names, and doctors categorize them by their frequency, which is the number of waves per second. Examples include alpha waves, delta waves ...

Mass General Brigham researchers have developed an AI tool that analyzes brain wave activity recorded during sleep using ...

In their report the researchers use these new vivid images of brain activity to illustrate how the sleep EEG multitaper spectrogram objectively reveals the detailed architecture of an entire night ...

Tiny Waves, Big Clues. The study focused on data from women over the age of 65. These women took part in an earlier sleep and health study and had normal thinking ability at the time.

Slow-wave sleep is the deepest phase of dreamless, non-rapid eye movement (NREM) sleep. On an electroencephalogram (EEG) recording, SWS is characterized by "slow" delta brain waves (1-4 Hz). This ...

EEG, BOLD, and CSF signals displayed a specific timing sequence during slow wave sleep, with neural rhythms preceding BOLD signals and CSF waves.

Research from Columbia University and NewYork-Presbyterian suggests that brain waves associated with sleep may help predict recovery in unresponsive patients with recent brain injuries. The study, ...

Certain factors, such as lack of sleep and certain medications, may show on an EEG as disrupted gamma waves and may relate to changes in someone’s ability to think and react.

EEG brain wave measurement is also possible. Emotiv, for example, offers wireless EEG setups ranging from full, wet-electrode caps to simple headsets. They even offer two-channel EEG earbuds.

After reviewing the EEG data, the team found that the brains of people with epilepsy were producing slow waves -- lasting less than one second -- while they were awake and taking part in the task.
