A neurocomputational model for cocaine addiction.

29 Sep 2009 Based on the dopamine hypotheses of cocaine addiction and the assumption of decrement of brain reward system sensitivity after long-term drug exposure, we propose a computational model for cocaine addiction. Utilizing average reward temporal ... Read more...

NCS-1 in the dentate gyrus promotes exploration, synaptic plasticity, and rapid acquisition of spatial memory.

8 Sep 2009 The molecular underpinnings of exploration and its link to learning and memory remain poorly understood. Here we show that inducible, modest overexpression of neuronal calcium sensor 1 (Ncs1) selectively in the adult murine dentate gyrus (DG) ... Read more...

Biochemical, behavioural and quantitative alterations in cerebellum of Swiss albino mice following irradiation and its modulation by Grewia asiatica.

30 Aug 2009 PURPOSE: To study the biochemical, quantitative histopathological and behavioural changes after 5 Gy whole body irradiation and its modulation by supplementation of Grewia asiatica extract (GAE) on male Swiss albino mice up to 30 days. MATERIALS AND ... Read more...
