Dataset of cortical activity recorded with high spatial resolution from anesthetized rats

The wideband, spontaneous recordings (n = 109) were acquired with a single-shank silicon-based probe having 128 densely packed recording sites arranged in a 32x4 array (Fiáth et al., 2018). The dataset contains the activity of a total of 7126 sorted single units extracted from all layers of the cortex.

Here, we share raw neural recordings, as well as spike times, extracellular spike waveforms and several properties of units packaged in a standardized electrophysiological data format. For technical validation of our dataset, we provide the distributions of derived single unit properties along with various spike sorting quality metrics.
