VUMC scientists record powerful signal in the brain’s white matter

Vanderbilt researchers report that when people who are having their brains scanned by fMRI perform a task, like wiggling their fingers, certain signals increase in white matter throughout the brain, which has long been thought to play a lesser role the more the brain’s more energetic gray matter.

Study suggests way to relieve cognitive deficits caused by Parkinson’s disease

Vanderbilt research raises the possibility of using DBS to slow the decline of cognitive function, a major source of disability, diminished quality of life, and death in more than three-quarters of patients with Parkinson’s disease.

Images predict functional decline

MRI brain scans at baseline for study participants 60 and older — who were free of clinical dementia at study entry — predicted a decline in independent function five years later.

Study examines impulsiveness in Parkinson’s disease

Vanderbilt researchers are studying aspects of dopamine release and its regulation in Parkinson’s patients with and without impulsive-compulsive behaviors.

Social behavior brain circuitry

Vanderbilt researchers have identified a novel mechanism regulating social behavior: Neuropeptide Y signaling in the nucleus accumbens brain region.

White matter and psychosis

The microstructure of white matter in the brain could be an important risk marker for psychosis, Vanderbilt researchers have discovered.
