Scientists have studied the main source of serotonin in the brain -- the dorsal raphe nucleus (DRN). By studying how activating the brain's 'serotonin center' affects awake animals for the first time, ...

Neurons deep in the brain not only help to initiate movement-they also actively suppress it, and with astonishing precision. This is the conclusion of a new study by researchers at the University of ...

Elevated pallidal beta power may serve as a biomarker for depression in Parkinson’s disease, paving the way for targeted DBS ...

A) Outline of basal ganglia anatomy in a coronal human brain section. B) UMAP clustering of nuclei from 12 brains based on snRNA-seq data. C) Wiring diagram of basal ganglia circuitry. D) Normalized ...

Human immunodeficiency virus (HIV) infections are still fairly common and an estimated 40 million people worldwide are currently living with this condition. The HIV virus attacks the body's immune ...

Using light stimulation and MRI, scientists compared the effects of stimulating the brain’s serotonin center in awake and anesthetized mice, showing a clear difference in activation levels between the ...
