Polytrode extracellular recordings with paired juxtacellular recordings

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:
