1024-channel electrophysiological recordings during resting state in V1 and V4 of macaque visual cortex
This respository contains the data associated to the publication "1024-channel electrophysiological recordings during resting state in V1 and V4 of macaque visual cortex" by Chen*, Morales-Gregorio* et al. Future updates of the dataset will be uploaded here.
Summary
Electrophysiological activity data was recorded from the visual cortex (V1, V4) of two rhesus macaques using 16 utah arrays, for a total of 1024 recording sites. The monkeys were instructed to perform several tasks:
- Resting state (RS),
- Receptive field mapping (RF) with sweeping bars,
- Signal to noise ratio (SNR) estimation from visual stimulation with a checkerboard.
All data was recorded at the Netherlands Institute of Neuroscience and processed jointly with the INM-6 at Juelich research center.
The raw data constist on the continuous measure of extracellular potentials at a sampling frequency of 30 kHz The raw data was processed into two widely used analog signals, the local field potential (LFP) and the multiunit activity envelope (MUAe), with sampling rates of 500 Hz and 1 kHz respectively. Metadata about the recording system, animal behaviour during the recordings, data quality and receptive field locations was collected and compiled into a single .odml file per session, provided under the \data directory of this repository.

Downloading the data
Using gin
Create an account on gin and download the gin client as described here. On your computer, log in using:
gin login
Clone the repository using:
gin get NIN/V1_V4_1024_electrode_resting_state_data
The cloning step can take a long time, due to the large amount of individual files. Please be patient.
Large data files will not be downloaded automatically, they will appear as git-annex links instead. We recommend downloading only the files you need, since the entire dataset is large. To get the contents of a certain file:
gin get-content <filename>
Downloaded large files will be locked (read-only). You must unlock the files using:
gin unlock <filename>
To remove the contents of a large file again, use:
gin lock <filename>
gin remove-content <filename>
Detailed description of the gin client can be found at the gin wiki. See the gin usage tutorial for advanced features.
Using the web browser
Download the files you want by clicking download in the gin web interface. Convenience summary tables of the data and sessions can be found in the summary above.
