The dissociation of temporal processing behavior in concussion patients: Stable motor and dynamic perceptual timing.

Temporal processing is an integral aspect of human cognition and perception. Recent studies have suggested that patients suffering from concussion exhibit a deficit in temporal processing, characterized by poor performance on a variety of timing tasks. However, the majority of studies focusing on temporal processing deficits in concussion have focused on visual timing mechanisms.

Zinc Exacerbates Tau Pathology in a Tau Mouse Model.

Hyperphosphorylated tau protein is a key pathology in Alzheimer's disease (AD), frontotemporal dementia, chronic traumatic encephalopathy, and Parkinson's disease. The essential trace element zinc exacerbates tauopathy in vitro as well as in a Drosophila model of AD. However, the interaction has never been assessed behaviorally or biochemically in mammals.
