Summary of the data

This dataset contains the data that accompanies Peron et al., 2020, Nature,

"Recurrent interactions in local cortical circuits".

It consists of two-photon imaging data, recorded at 7 Hz in 600 x 600 um planes, of which 3 are imaged simultaneously (this is a subvolume).  There are typically 4-6 such subvolumes per animal.  Data for a given subvolume typically was collected for 2-4 days prior to, and another 2-4 days after multiphoton ablation was performed.  Ablation was targeted to specific neurons (typically 10-20).  Whisker videography and behavioral data is also represented.

You are strongly advised to download the accompanying code, which will reproduce the majority of the figures from the aforementioned manuscript, from the github repository available at:

This code will provide a good guide for loading data.

Format of the data

The data is stored in MATLAB structures. Details about the data are in the document linked-to at the end of this page. Total data size is about 113 GB.
