About pfc-2

Information about pfc-2 (prefrontal cortex, number 2).


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.

More information is given in document linked to at the end of this webpage.

Format of the data.

The format of the data is the same as the hc-1, hc-2, hc-3, hc-4 and th-1 data sets.   The data for each session is stored in a tar.gz file. The total size of the data is about 308 GB compressed. Not all of the data needs to be downloaded to use the data set.  Session EE0708/EE.188 includes a MATLAB file giving information about neurons detected in the session that were used to produce figures 2A and 3D in the paper mentioned above.
