Phase coding of spatial representations in the human entorhinal cortex

Supporting Preprocessed Electrophysiology Data for the article titled "Phase coding of spatial representations in the human entorhinal cortex".

Data were preprocessed and analyzed using Matlab.

Data, after decompression, are organized hierarchically in folders and subfolders (two levels).

Main folder names are composed as subjectID_date_EC_DATA_taskNo

Sub-folders named as:  CHn_single-unit ID 

[subjectID, date, task num] + [Electrode channel, and single-unit ID] 

subjectID: (subject1, subject2)

date: mmm-dd

task: (1,2,3,4) Virtual environments (1: backyard, 2: Louvre, 3: Luxor, 4: desert)

electrode Channel: CH1,CH2, CH3, CH4, CH5

single-unit ID: 0, 1, 2, 3, 4, 5, 6

For each channel and single-unit, the following 9 datasets were computed and saved. For instance, for the first electrode and first single-unit class (CH=1, cell ID= 0):

CH1_Clu0.mat                                  -- Summary of firing features of this single-unit including firing rate, and grid score of the cell. (In Matlab mat format)
CH1_Clu0_MeanPhaseMap.csv       -- Mean spike phase map relative to gamma-band LFP
CH1_Clu0_Phase.csv                       -- Spike phase CH1_Clu0_spikeData.csv
CH1_Clu0_spkT.csv                          -- Spike times in increental order
CH1_Clu0_VarPhaseMap.csv           -- Map of the variance of spike times in increental order
CH1_Clu0_xval.mat                          --  Summary of firing features of 50% of single-unit spikes (every other spike) for cross-validation purposes. (In Matlab mat format)
CH1_Clu0_xyPos.csv                       -- X,Y coordinates of the avatar's position in 1 ms resolution. In other words, the path taken by the avatar sampled at 1 kHz.
CH1_Clu0_XYspkT.csv                     -- X,Y coordinates of the avatar at moments of spikes. In other words, the location in space where a spike was fired by the putative neuron.
