Simultaneous recordings from rhesus macaque V1 and V4 during a selective attention task. Recorded in the lab of Alexander Thiele at Newcastle University, UK.
These preprocessed data allow reproduction of the main analyses and results reported in the paper "Dopamine influences attentional rate modulation in Macaque posterior parietal cortex", van Kempen (2022) Nature Scientific Reports (URL to follow).

Data is organised by subject and recording date.
The folder data/processed contains the files necessary to replicate the main results described in this article.
Output from the analyses and the pooled results will be stored in data/analysed and data/population, respectively.
In each recording folder, you can find the following files:

Unit activity was extracted by manaul spike sorting. This population activity is stored in unit.mat.
Inside this file, you'll find the following variables:
StimAlign: {3x312 cell}
CueAlign: {3x312 cell}
Dim1Align: {3x312 cell}
idx_include_trials: 3x312 (logical)
waveform: 1x1 (struct)
The fields ...Align are variables with the data aligned to each of the events. This is a cell array of size (number of units × number of trials). Each cell contains spike times relative to the event.
The variable idx_include_trials contains logical indices that indicate which trials to include for which of the units and waveform contains the spike waveform for each unit.
The file trialdata.mat contains the metadata about each trial, e.g. the condition number, the drug condition, etc.
