Each MATLAB .mat file contains an electrophysiological recording of a single striatal interneuron and coincident electrocorticogram (ECoG). Neurons are only included in this data set if they were juxtacellularly labelled following recording, recovered post-mortem and confirmed to express either parvalbumin (PV), choline acetyl transferase (ChAT), nitric oxide synthase (NOS) or calretinin (CR).
All recordings were made from Sprague Dawley rats anaesthetised with urethane and supplemental doses of ketamine and xylazine. Detailed methods can be found in the references below.
Recordings were made in to brain states: slow wave activity (SWA) and cortical activation. Recordings are divided in to folders based on both their neurochemical identity and the state in which they were recorded.
Each folder contains neurons of a single neurochemical identity (chat, pv, nos or cr) recorded in one brain state (swa or Act).
Some neurons were recorded in both states. Names of neurons are consistent throughout so that neurons recorded in both states can be compared.
The electrophysiological data and their recording parameters are stored as structure arrays (“ephys”) with the following fields:
Data values of the wideband recording from the glass electrode (including both local field potential and action potential components).
Data values for the online highpass filtered 300 –5000 Hz wideband signal used to sort action potentials.
Binary representation of the spike times of the sorted action potentials
Data values for coincident ECoG recording
Time axis for all electrophysiological recordings.
Sampling rate of all electrophysiological recordings (all 16000)
Amplitude unit for all electrophysiological recordings (all mV)
