About hc-5

Information about the hc-5 data set.

Summary.

The CRCNS.org hc-5 data set contains recordings made using a silicon probe from three areas from a single rat that was performing different behavioral tasks.  The three regions recorded from are left and right hippocampal CA1 and right entorhinal cortex.  The tasks are a left/right alternate selection task, wheel running, and platform exploration.   The neural data was recorded on 125 channels. Included in the data set are the following items:

  • Weveforms of putative spikes extracted from original raw broadband data
  • LFPs (local field potentials)
  • Results of spike sorting
  • Information about the animal behavior during the experiment

Several publication based on some of the data are:

Internally generated cell assembly sequences in the rat hippocampus. Pastalkova E, Itskov V, Amarasingham A, Buzsáki G. Science. 2008 Sep 5;321(5894):1322-7

Theta oscillations provide temporal windows for local circuit computation in the entorhinal-hippocampal loop. Mizuseki K, Sirota A, Pastalkova E, Buzsáki G., Neuron. 2009 Oct 29;64(2):267-80.

Theta sequences are essential for internally generated hippocampal firing fields. Wang Y, Romani S, Lustig B, Leonardo A, Pastalkova E. Nat Neurosci. 2014 Dec 22. [Epub ahead of print]

Format of the data.

The format of the data is the same as for the hc-2 and hc-3 data sets (see links to documentation files at bottom of page).  In addition, most sessions contain a MATLAB file that has much of the data in a format that is easy to wok with in MATLAB.  Details of the data format are provided in documents listed at the bottom of this page.
