Surprise response as a probe for compressed memory states

This code accompanies the data published with the paper:

Levi-Aharoni H, Shriki O, Tishby N (2020) Surprise response as a probe for compressed memory states. PLOS Computational Biology 16(2): e1007065.

The data can be downloaded directly from here.

After running this code on a dataset you will have the following arrays:

• full_data_new - all EEG data and trigger channel (last channel)
• time - time progress during the experiment. Sampling rate is 256Hz. Each time point corresponds to an EEG sample. Time t=0 corresponds to the beginning of recording.
• Trig - same as trigger channel (last channel in full_data_new). Trigger codes: 514 - beginning of measurement, 100/200 - end of block 1/2 - high frequency, 3/4 - low frequency

If using the corresponding stimSeq file, note that in a few datasets there are ~1-2 trials missing (missed triggers) and should be taken care of (should be manually removed in the analysis)

Example:

load('S1\Data_S1.mat')
prepare_data_and_triggers_P300Dataset;
