Functions for Basic e-phys

Authors: Konstantinos Nasiotis

After performing the spike sorting and the conversion to the LFPs users have access to these invaluable types of information.

LFPs can be analyzed using the extensive library of methods that have been used in EEG and MEG research already present in Brainstorm. These signal processing libraries include preprocessing, artifact removal, time-frequency, connectivity, statistics and several other tools that are essential for analyzing electrophysiological data.

Spiking activity can be analyzed in a set of functions that is present in the Electrophysiology library (Run->Electrophysiology), and help researchers understand their selectivity and interaction with the LFPs.

For the purpose of the tutorial, the timings around the presentation of the Images are selected as the segment of interest of the recordings.

To import those segments, users should right click on the Link to raw file (On the LFP file)-> Import Recordings.

This will create 863 new entries in the database, since each event type (Stim On: …) was presented 108 times (Stim On -1/4 107 times).

All event types should be imported, as in the screenshot below:
