About hc-9

Information about the hc-9 data set.


This data set includes the raw data files from some experimental O-LM cells featured in Quattrocolo and Maccaferri (2013) that were later used to constrain the model cells of the model CA1 neural network published in: Marianne J. Bezaire, Ivan Raikov, Kelly Burk, Dhrumil Vyas, and Ivan Soltesz. Interneuronal mechanisms of hippocampal theta oscillations in full-scale models of the CA1 circuit. Under Review, 2016.

Results from the experiments are described in:

Giulia Quattrocolo and Gianmaria Maccaferri. Novel GABAergic circuits mediating excitation/inhibition of Cajal-Retzius cells in the developing hippocampus. The Journal of Neuroscience, 33(13):5486–5498, 2013. doi: 10.1523/JNEUROSCI.5680-12.2013

Format of the data

The data consists of the full current injection sweep for three different cells. The files are in a custom format (ATF; AxoClamp text file) but are tab-delimited ASCII text files so they can be read by almost any software application. Information about the format and freely available software to read it (SimTracker) are described in the data description document linked to at the bottom of this page. Total size of the data is about 5 MB.
