EEG epoching is a procedure in which specific time-windows are extracted from the continuous EEG signal. These time windows are called “epochs”, and usually are time-locked with respect an event e.g. a visual stimulus. If your EEG data are in a matrix [channel x time] where time is the complete continuous EEG signal, after the epoching procedure

EEG has a very high temporal resolution compared to fMRI. It can pick up the rapid reactions of the brain that happen at the speed of milliseconds, which allows it to sync very accurately what happens in the brain and in the environment. EEG is recorded at sampling rates between 250 and 2000 Hz in clinical and research settings.

An electroencephalogram (EEG) is a recording of brain activity. During the test, small sensors are attached to the scalp to pick up the electrical signals produced when brain cells send messages to each other. 2017-04-01 · Electroencephalography (EEG, see Glossary) and magnetoencephalography (MEG) are the most powerful techniques for noninvasively studying the electrophysiological dynamics of the brain, and linking those dynamics to cognition and disease. The term ‘EEG’ is used throughout this paper for convenience, but the discussion applies equally to MEG. The clinical definition of EEG is the recording of brain activity over a period of time. EEG electrodes pick up on and record the electrical activity in your brain. The collected signals are amplified and digitized then sent to a computer or mobile device for storage and data processing.

EEG (electroencephalogram) a recording of the electrical changes occurring in the brain, produced by placing electrodes on the scalp and amplifying the electrical potential developed. The EEG shows three main types of wave called alpha, beta and delta, that differ in their rates of production.

These then create an electrical pulse. 2015-09-01 · Here, we argue that the actual temporal resolution of conventional (scalp potentials) EEG is overestimated, and that volume conduction, the main cause of the poor spatial resolution of EEG, also distorts the recovered time course of the underlying sources at scalp level, and hence degrades the actual temporal resolution of EEG. Modern EEG machines have excellent time resolution, meaning they can easily detect brainwave activity within millisecond timescales.
