Apr 10, 2024 · Hunger increases dopamine release in the nucleus accumbens in response to food or cues predicting food 6-8 highlighting the interaction between homeostatic and motivational systems. Chemogenetic activation of AgRP neurons increases nucleus accumbens dopamine release and VTA dopamine neural activity to food, 8 , 9 demonstrating that AgRP neurons ...
1 day ago · The study identifies specific neurons in the nucleus accumbens that are affected by both natural rewards and drugs, explaining the mechanism behind the powerful grip of addiction. Advanced tools allowed researchers to observe how repeated drug exposure alters neuronal responses, increasing the preference for drugs over natural rewards.

Apr 8, 2024 · 5 Basal forebrain. The basal forebrain (BF) is a heterogenous region composed of multiple areas, including substantia innominate, nucleus accumbens and ventral pallidum of the basal ganglia, bed nucleus of the stria terminalis, the preoptic area, the nucleus basalis of Meynert, the septal nuclei and diagonal band of Broca (Tsanov, 2022).
2 days ago · The autonomic motor system is distinct from the somatic motor system, which controls skeletal muscle. Whereas somatic motor neurons regulate contractions of striated muscles (), autonomic motor neurons regulate blood vessels, the heart, the skin, and visceral organs through synapses upon smooth and cardiac muscle cells, upon glands cells that serve endocrine and exocrine functions, and upon ...
