The gamma response to colour hue in humans: evidence from MEG

Data from the publication: "The gamma response to colour hue in humans: evidence from MEG", Plos One, 2021Each file contains virtual sensor data for an individual participant from one of the two experiments reported in the paper. The first column in each file contains the time (relative to stimulus onset) of the corresponding sample in seconds. Each subsequent column contains data from an individual trial, with the first row giving the stimulus condition for the corresponding trial. (Note that due to the way the data was pre-processed, trials are grouped by condition rather the being stored in their original presentation order.) The virtual sensor data contained in the files is unitless due to the beamformer weights having been normalised. In experiment 1 there are four conditions of colour (red, green, blue, purple) and one condition in which a grating was presented (labeled simply as 'grating').In experiment 2 conditions are labelled first by the level of colour contrast (either high or low) and the colour pair (r = red, b = blue, g = green). The order that the colours were presented in each trial is reflected by the order of the letters in the condition label (e.g. rb = red-blue starting with red as the first colour; br = red-blue starting with blue). There are eight conditions (x 2 orders) in total.Trials excluded due to artefacts are not included in the datasets. This means that the number of trials per participant (and per condition for each participant) are not identical across trials.
