(2010), where a full description of the methods can be found.<br>50 Left/Right (Gauche/Droite, excuse my French) whisker stimulations (some lacking in one animal).<br>Signals were referenced to an electrode placed above the cerebellum, online filtered 1-500 Hz, and digitized at 2 kHz.<br><br>Each directory contains data files from one animal: Epochs for left ('G') and right ('D') stimulation plus an average for each condition.<br>Each file contains 15-channel epicranial EEG, the reference electrode has been removed.<br>Stimulus onset is at time-frame 120.<br>The EEG files (.eph) are plain text files with a header: nr of channels, nr of time frames, sampling rate (Hz).<br>Openable in Cartool software, freely available here: https://sites.google.com/site/fbmlab/cartool<br><br>Electrode layout file: electrodeLayout_15chan.els<br>A text file with 15 electrode coordinates, can be linked to the .eph files for topographic ERP views using Cartool software.<br><br>The electrode layout is shown in rodent_15ch_electrodeLayout_left-right.PNG<br>For left stimuli, e4 is the electrode over contralateral S1, for right stimuli it is e12. <br><br>#---------- Animal names and numbers<br>1.
