This repository contains the ephys data related to the article "Resolving and rescuing developmental miswiring in a mouse model of cognitive impairment".
|
|
|
We provide recordings from the prefrontal cortex of 61 not-anesthetized mice of 4 to 10 days of age.
|
|
|
Following the structure of the article, the dataset can be summarized as containing recordings of:
|
|
|
- - 14 P4-6 control mice
|
|
|
+ - 13 P4-6 control mice
|
|
|
- 13 P4-6 dual-hit GE mice
|
|
|
- 16 P8-10 control mice

-All recordings contain 16 channels recorded with a Neuronexus 4x4 4-shank electrode. Neighboring channels on the same shank are 100 micrometers apart. Channels at the same depth and on neighboring shanks are 125 micrometers apart.
|
|
|
-Channels 1 to 4 are the most medial ones and channels 13 to 16 the most lateral.
|
|
|
-The probe spans from layer II to layer V/VI of the prelimbic section of the prefrontal cortex.
|
|
|
-Channels 1-5-9-13 are the most superficial, and 4-8-12-16 the deepest.
|
|
|
-The position of every electrode has been post-mortem histologycally reconstructed and the column "shift" in Recording Metadata.xlsx indicates the optimal shift (in shanks) to realign the channels. A positive shift indicates that the channel was too inserted too medially (e.g. shift = 1 -> channels 5:8 correspond to channels 1:4 of an optimally inserted electrode), whereas a negative shift indicates a lateral insertion (e.g. shift = -2 -> channels 1:4 correspond to channels 9:12 of an optimally inserted electrode).

+ Signal as been common average rereferenced (the mean of all channels has been subtracted).
|
|
|
+ Most recordings are ~ 1h 30' of uniterrupted recording. All recordings are at least 50' long.
|
|
|
+ Data is in a single vector form. The first sixteen data points correspond to the first millisecond of recording for the sixtenn channels (from channel 1 to 16). The second sixteen data points to the second millisecond and so on.
