Selective serotonin receptor stimulation of the medial nucleus accumbens causes differential effects on food intake and locomotion.

29 Sep 2009 Substantial evidence suggests that pharmacological manipulations of neural serotonin pathways influence ingestive behaviors. Despite the known role of the nucleus accumbens in directing appetitive and consummatory behavior, there has been little ... Read more...

Similar neurons, opposite adaptations: psychostimulant experience differentially alters firing properties in accumbens core versus shell.

28 Sep 2009 The principal components of neuronal excitability include synaptic and intrinsic membrane parameters. While recent studies indicate that cocaine exposure can induce widespread changes in synaptic function in the neural circuits for reward, intrinsic ... Read more...

Cooperative activity of neurons in the nucleus accumbens and frontal cortex in cats trained to select reinforcements of different value.

21 Sep 2009 Results obtained at the level of the organization of interneuronal interactions of cells in the nucleus accumbens and frontal cortex revealed the features of the involvement of this component in "impulsive" and "self-controlled" behavior, consisting ... Read more...

Technical information about 'Nucleus Accumbens'

Definition: Collection of pleomorphic cells in the caudal part of the anterior horn of the lateral ventricle, in the region of the olfactory tubercle, lying between the head of the caudate nucleus and the anterior perforated substance. It is part of the so-called ventral striatum, a composite structure considered part of the basal ganglia.
