# 2025 - Autism Widefield
2+
3+
Widefield data were collected in 5 mice performing the [IBL task](https://pubmed.ncbi.nlm.nih.gov/34011433/).
4+
Animals were either wildtype, or from the autism models TRE-GCaMP6s-CAMKII; NRXN KO.

## Overview of the Data
2020
We have released data from 198 Neuropixel experimental sessions, with single Neuropixel recordings, referred to as probe insertions. Those were obtained with 62 genetically modified subjects performing the IBL task.
21-
As output of spike-sorting, there are XXX units; of which XXX are considered to be of good quality. In total, XXX brain regions were recorded in sufficient numbers for comparison with IBL’s analyses [(IBL et al. 2023)](https://doi.org/10.1101/2023.07.04.547681).
21+
As output of spike-sorting, there are 71,067 units; of which 12,163 are passing IBL automated quality control.

IBL aims to understand the neural basis of decision-making in the mouse by gathering a whole-brain activity map composed of electrophysiological recordings pooled from multiple laboratories.
44
We have systematically recorded from nearly all major brain areas with Neuropixels probes, using a grid system for unbiased sampling and replicating each recording site in at least two laboratories.
55
These data have been used to construct a brain-wide map of activity at single-spike cellular resolution during a [decision-making task]((https://elifesciences.org/articles/63711)).

mouse decisions and response times; and mouse pose information from video recordings and DeepLabCut analysis.
