Nonhuman Primate Reaching With Multichannel Sensorimotor Cortex Electrophysiology: Broadband For Indy_20170124_01

This dataset supplements https://doi.org/10.5281/zenodo.583331 .<br> <br> <strong>General description.</strong> These data consist of extracellular neural recordings ("broadband") from primate subject "Indy", session identifier "indy_20170124_01". <strong>Filtering. </strong>The data are sampled at 24414.0625 Hz and are unfiltered, except for an anti-aliasing filter built-in to the recording amplifier: a 4th order low-pass with a roll-off of 24 dB per octave at 7.5 kHz, operating at the sampling rate. <strong>File format.</strong> The data are contained in an HDF5 formatted file, organized according to the Neurodata Without Borders (NWB) version 1.0.6 specification. <strong>Datasets. </strong>A few of the relevant dataset paths are listed here for convenience. In the below, <em>n</em> refers to the number of recording channels and <em>k</em> refers to the number of samples. "/acquisition/timeseries/broadband/data" - k x n The broadband neural recordings. "/acquisition/timeseries/broadband/data/conversion" (scalar attribute) When multiplied by each sample converts the data into units of volts. "/acquisition/timeseries/broadband/timestamps" - k x 1 Timestamps for each sample, seconds. "/general/extracellular_ephys/electrode_map" - n x 3 The relative coordinates of each electrode contact (x, y, z), meters.
