Motivation to Achieve Goals May Depend on Anxiety Level

The motivation to exert sustained effort to achieve a goal following stress exposure depends on an individual's level of trait anxiety. The expression of CRHR1 in dopaminergic neurons in the ventral tegmental area connects anxiety to either boosted or diminished motivation levels.

Beyond Dopamine: New Reward Circuitry Discovered

Researchers have identified a new reward system in the brain. The study found long-range GABA neurons from the ventral tegmental area to the ventral nucleus accumbens shell are engaged in reward and reinforcement behaviors. This GABAergic projection inhibits cholinergic interneurons.
