Sex counts in the brain as seasons change
Mar. 2, 2023—Photoperiod, or length of day, has sex-specific impacts on dopamine dynamics in the brain, offering insights into sex differences in neuropsychiatric disorders, Vanderbilt researchers report.
Social behavior brain circuitry
Nov. 3, 2022—Vanderbilt researchers have identified a novel mechanism regulating social behavior: Neuropeptide Y signaling in the nucleus accumbens brain region.
Histamine circuits in brain reward center
Oct. 29, 2020—Histamine — commonly associated with allergies — also has a signaling role in the brain’s reward center and may offer a novel target for treating addiction.
Shaping reward circuits
May. 18, 2018—Using techniques to control and monitor the activities of individual neurons, Vanderbilt investigators are probing the brain’s reward circuitry.
An immune regulator of addiction
Aug. 4, 2017—Although drug addiction is classically studied in a neuron-centric way, Vanderbilt researchers have discovered that the immune system also plays a critical role.
Probing drug abuse circuitry
Nov. 4, 2016—Vanderbilt researchers have identified cocaine-induced modifications at specific neuronal connections, which could aid the development of new therapies for substance abuse disorders.
Optogenetics sheds new light on brain’s behavior modulators
Nov. 6, 2014—A new light-based technology is allowing scientists to peer deep into the brain and alter animal behavior with the “flip of a switch.”
