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.

Green Apple Flavor in Vapes Enhances Nicotine Reward

Common green apple flavorant farnesene enhances nicotine reward in mouse models. The flavorant is also rewarding on its own. Researchers say with or without nicotine, flavored vapes, especially those containing farnesene, pose potential neurological risks, including addiction.

Exercise boosts motor skill learning via changes in brain’s transmitters

Neurons in the caudal pedunculopontine nucleus, an area of the brain that regulates motor coordination, switch neurotransmitters from acetylcholine to GABA as a result of exercise. The switch appears to provide feedback control that regulates motor coordination and skill learning.
