Cellular and network mechanisms of operant learning-induced compulsive behavior in Aplysia.
2 Jun 2009 
BACKGROUND: Learning in exploratory and goal-directed behaviors can modify decision-making processes in the initiation of appropriate action and thereby transform the irregular and infrequent expression of such behaviors into inflexible, ...

Jun 2009 The negative motivational aspects of withdrawal include symptoms of both anxiety and depression, and emerge after termination of chronic drug use as well as after acute drug exposure. States of acute withdrawal are an inherent part of intermittent ...

Rat prefrontal cortical neurons selectively code strategy switches.
Jun 2009 Multiple memory systems are distinguished by different sets of neuronal circuits and operating principles optimized to solve different problems across mammalian species (Tulving and Schacter, 1994). When a rat selects an arm in a plus maze, for ...

Stress prompts habit behavior in humans.
Jun 2009 Instrumental behavior can be controlled by goal-directed action-outcome and habitual stimulus-response processes that are supported by anatomically distinct brain systems. Based on previous findings showing that stress modulates the interaction of ...

30 May 2009 Alterations in nutritional factors during early development can exert long-term effects on growth, neural function, and associated behaviors. The lipid component of milk provides a critical nutritional source for generating both energy and essential ...

30 May 2009 The melanocortin (MC) system is composed of peptides that are cleaved from the polypeptide precursor proopiomelanocortin (POMC). Recent pharmacological and genetic evidence suggests that melanocortin receptor (MCR) signaling modulates ...

Delta FosB overexpression in the nucleus accumbens enhances sexual reward in female Syrian hamsters.
30 May 2009 Repeated activation of the mesolimbic dopamine system results in persistent behavioral alterations accompanied by a pattern of neural plasticity in the nucleus accumbens (NAc). As the accumulation of the transcription factor Delta FosB may be an ...

Effects of skilled training on sleep slow wave activity and cortical gene expression in the rat.
30 May 2009 STUDY OBJECTIVE: The best characterized marker of sleep homeostasis is the amount of slow wave activity (SWA, 0.5-4 Hz) during NREM sleep. SWA increases as a function of previous waking time and declines during sleep, but the underlying mechanisms ...

30 May 2009 Developmental studies of pre- to postnatal continuities in rhesus monkeys sometimes require infants be reared with their mothers. However, complications during pregnancy or experimental designs may require cesarean delivery. Owing to lack of ...
