Description

Simultaneous electrophysiological recordings of ensembles of isolated neurons in rat medial prefrontal cortex and intermediate CA1 area of the hippocampus during a working memory task. Recorded by Shigeyoshi Fujisawa. [about]

This dataset of multi single neuron recording was acquired from three rats (EE, FF, GG) while performing a working memory task. Neuronal activity was monitored simultaneously in the PFC (64 channels) and the intermediate CA1 (32 channels) of the hippocampus. In one rat (EE), sleep was also recorded before and after the task. Details of the task were described in:

Fujisawa S, Amarasingham A, Harrison MT, Buzsáki G; “Behavior-dependent short-term assembly dynamics in the medial prefrontal cortex” Nature Neuroscience 2008 Jul;11(7):823-33.; doi:10.1038/nn.2134

The data was obtained during 52 main recording sessions and nine short test sessions.  The total duration of all the sessions is about 23.37 hours.  The raw (broadband) data was recorded at 20KHz.  The raw data was processed to extract the LFPs and detect spikes. Included in the data set are:

  • Raw data
  • Times and waveforms of detected potential spikes
  • Results of spike sorting
  • LFPs
  • The coordinate and direction of the mice head and video files from which the positions were extracted
  • Metadata tables giving properties of the neurons and characteristics of the recording sessions.
