The role of the dorsal raphe nucleus in the development, expression, and treatment of L-dopa-induced dyskinesia in hemiparkinsonian rats.

29 Jun 2009 Convergent evidence indicates that in later stages of Parkinson's disease raphestriatal serotonin neurons compensate for the loss of nigrostriatal dopamine neurons by converting and releasing dopamine derived from exogenous administration of the ... Read more...

Adolescent male rats exposed to social defeat exhibit altered anxiety behavior and limbic monoamines as adults.

30 May 2009 Social stress in adolescence is correlated with emergence of psychopathologies during early adulthood. In this study, the authors investigated the impact of social defeat stress during mid-adolescence on adult male brain and behavior. Adolescent ... Read more...

Learning strategies during fear conditioning.

29 Apr 2009 This paper describes a model of fear learning, in which subjects have an option of behavioral responses to impending social defeat. The model generates two types of learning: social avoidance and classical conditioning, dependent upon (1) escape ... Read more...
