About spe-1
Summary.
In this dataset, we recorded simultaneously from the same cortical neuron using patch-clamp and extracellular (Neuropixel, 384 channel) probes, in urethane-anaesthetized rats (no stimulus, just spontaneous activity). A total of 43 neurons were recorded from in primary motor and somatosensory cortex. 38 neurons were recorded in cell-attached mode and 5 in whole-cell. Out of the 43 neurons that we patched, 21 showed clear extracellular spike waveforms, and for 10 of these the peak-peak amplitude exceeded 50 µV. For each neuron, we provide the raw extracellular recording file (action potential band, high-pass filtered at 300 Hz) and the corresponding patch-clamp recording, as well as sync channels for the two modalities, sample number for spike peaks in the patch-clamp recording, and corresponding sample numbers in the extracellular recording. Results from the experiments and detailed information about the dataset are described in:
We have also set up a companion repository featuring all the code used in the above publication, indications on how to load and interact with the dataset, and proposed follow-up projects for collaboration. Interested parties are welcome and encouraged to collaborate on these projects:
