Decreased firing of striatal neurons related to licking during acquisition and overtraining of a licking task.

2 Nov 2009 Neurons that fire in relation to licking, in the ventral part of the dorsolateral striatum (DLS), were studied during acquisition and performance of a licking task in rats for 14 sessions (2 h/d). Task learning was indicated by fewer errors of ... Read more...

Corticostriatal Interactions during Learning, Memory Processing, and Decision Making.

12 Oct 2009 This mini-symposium aims to integrate recent insights from anatomy, behavior, and neurophysiology, highlighting the anatomical organization, behavioral significance, and information-processing mechanisms of corticostriatal interactions. In this ... Read more...

Neurosphere cell differentiation to aldynoglia promoted by olfactory ensheathing cell conditioned medium.

29 Sep 2009 Cells from central nervous system with morphology similar to radial glia and properties intermediate between astrocytes and Schwann cells were called growth-promoting glia or aldynoglia. These cells are present in adult brain olfactory bulb, ... Read more...

Technical information about 'Corpus Striatum'

Definition: Striped gray and white matter consisting of the NEOSTRIATUM and paleostriatum (GLOBUS PALLIDUS). It is located in front of and lateral to the thalamus in each cerebral hemisphere. The gray substance is made up of the CAUDATE NUCLEUS and the lentiform nucleus (the latter consisting of the GLOBUS PALLIDUS and PUTAMEN). The white matter is the internal capsule.

Descriptor UI: D003342
