Description

This dataset is from a neural recording experiment conducted on a single adult female Sprague Dawley rat using a custom-made electrode array (10 wire hooks connected as isolated dipoles, with an effective inter-channel spacing of 1 mm) and commercial amplifiers and instrumentation. The dataset contains 20 recordings all of length 250 ms with a sampling rate of 50 kHz. The first 10 recordings were made with the animal at rest and are located in a folder called “Resting”, the filenames are timestamps that correspond to the time the recordings were started (1551.mat to 1608.mat). The second 10 recordings were made while the L5 dermatome was stimulated and are located in a folder called “Cutaneous Stimulation” and likewise the filenames are timestamps that correspond to the time the recordings were started (1554.mat to 1612.mat). The files are all stored as standard MATLAB data files are openable with a wide range of software packages including Python via the SciPy package. Within each data file there is a single vector called “rawdata” that is a 125,000 x 6 vector where the first column is a time vector and columns 2 thru 6 are Channel 1 thru Channel 5, where Channel 1 represents the most distal dipole, i.e the closest to the tail.
