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.

EEGLAB also includes meth- locking events in single data trials. ods allowing users to remove data channels, epochs, and/or Currently, most EEG researchers still interpret their components dominated by non-neural artifacts, by accept- data by measuring peaks in event-locked ERP averages. We go through and extract epochs for every event labeled with "rest" or "some". The epoch runs from -0.2 seconds to 1.5 seconds -- that is, 1.5 seconds after the critical word plus a 200 ms baseline prior to the critical word. 9.8. Data Type Formatting Functions. The PostgreSQL formatting functions provide a powerful set of tools for converting various data types (date/time, integer, floating point, numeric) to formatted strings and for converting from formatted strings to specific data types.

By simply adding EEGlab to the path and typing 'eeglab' in the command window we can load the toolbox and its GUI. The next step is to load the channel locations. This step is essential for further...To begin, in EEGLAB, go to Tools->Extract Epochs.
