The ascending arousal system promotes optimal performance through mesoscale network integration in a visuospatial attentional task

The ascending arousal system promotes optimal performance through mesoscale network integration in a visuospatial attentional task

Previous research has shown that the autonomic nervous system provides essential constraints over ongoing cognitive function. However, there is currently a relative lack of direct empirical evidence for how this interaction manifests in the brain at the macroscale level. Here, we examine the role of...
