About spe-2

Information about spe-2 (simultaneous patch and extracellular 2).

Summary.

Simultaneous extracellular and juxtacellular recordings were obtained from the cortex of ketamine-anesthetized rats (spontaneous activity). Extracellular recordings were carried either using polytrodes with 32 or 128 electrodes arranged in dense arrays. Twenty-two neurons were recorded with a distance less than 200 µm between the juxtacellular pipette tip and the closest extracellular electrode. For each paired-recording, we provide the extracellular recording and the corresponding juxtacellular recording. Detailed information about the dataset is described in:

Neto, J. P., Lopes, G., Frazão, J., Nogueira, J., Lacerda, P., Baião, P., … Kampff, A. R. (2016). Validating silicon polytrodes with paired juxtacellular recordings: method and dataset. Journal of Neurophysiology, 116(2), 892–903. http://doi.org/10.1152/jn.00103.2016.
