An ERP (Event Related Potential) occurs in response to a specific stimulus. This stimulus may be a sensory, cognitive, or motor event. The ERP is the time-locked average of an EEG over many trials involving the same event. The repetition reduces the EEG’s inherent signal to noise ratio, so the specific potential related to the event is displayed.
The analysis capabilities of LabScribe can be extended by using various open source EEG analysis programs such as:
EEGLAB : EEGLAB is an interactive Matlab toolbox for processing continuous and event-related EEG, MEG and other electrophysiological data incorporating independent component analysis (ICA), time/frequency analysis, artifact rejection, event-related statistics, and several useful modes of visualization of the averaged and single-trial data.
SleepSMG: an open source matlab user interface for scoring sleep and comparing sleep scores across individuals.
