VD-EEG

Behaviour and EEG recorded during the touchscreen Visual Disrimination task performance in rats.

.smr files contain raw EEG data of rats' epidural EEG recordings. Subjects were marked with _S001-S012 in the .smr file names.

Electrode channel numbers

  1. VISUAL (OCCIPITAL) LEFT (VL)
  2. VISUAL (OCCIPITAL) RIGHT (VR)
  3. PARIETAL LEFT (PL)
  4. PARIETAL RIGHT (PR)
  5. "-"
  6. "-"
  7. FRONTAL LEFT (FL)
  8. FRONTAL RIGHT (FR)

Bad Channels in each rat: 5, 6 (no electrode was implanted)

samplingRate = 10000;

triggers: channel 12- correct touch channel 13- incorrect touch channel 14- image displayed channel 15- tray entry

Data preprocessing:

High Pass Filter: 1 Hz Low Pass Filter: 80 Hz Notch: 45-55 Hz ReSampling: 1000 Hz Artefact selection by ICA and visual inspection Epoching: -1.5 +1.5 sec (t=0: correct touch) Baseline: -1 -0.7 sec Data were re-referenced to the average
