How silent is the brain: is there a “dark matter” problem in neuroscience?

Whether there is an underlying neural code that can explain information transfer in the brain has yet to be determined. This paper explores the idea that more neurons than we currently appreciate may live near dormancy and how those quasi-quiescent states contribute to computation in the brain.

Optogenetic Stimulation of Frontal D1 Neurons Compensates for Impaired Temporal Control of Action in Dopamine-Depleted Mice

A look at how D1 dopamine receptors might play a role in temporal processing (based on an action performed). Interestingly, a 2 Hz (delta band) stimulation improves performance.

Double dissociation of single-interval and rhythmic temporal prediction in cerebellar degeneration and Parkinson’s disease

This paper is one among many that contrast the presumes (and tested) roles of the basal ganglia and cerebellum in performing actions that are either rhythmic or based on single intervals.
