Systemic RNA interference for the study of learning and memory in an insect.

28 Apr 2009 RNA interference (RNAi) is a powerful technique for the study of molecular mechanisms underlying many biological processes, including brain functions. Among methods for RNAi, systemic administration of double-stranded RNA (systemic RNAi) is the most ...

The orbitofrontal cortex and ventral tegmental area are necessary for learning from unexpected outcomes.

28 Apr 2009 Humans and other animals change their behavior in response to unexpected outcomes. The orbitofrontal cortex (OFC) is implicated in such adaptive responding, based on evidence from reversal tasks. Yet these tasks confound using information about ...

Differential roles of the fan-shaped body and the ellipsoid body in Drosophila visual pattern memory.

21 Apr 2009 The central complex is a prominent structure in the Drosophila brain. Visual learning experiments in the flight simulator, with flies with genetically altered brains, revealed that two groups of horizontal neurons in one of its substructures, the ...

Impaired fear response in mice lacking GIT1.

17 Apr 2009 G protein-coupled receptor kinase interacting protein 1 (GIT1) belongs to the family of Arf GAP proteins and has been implicated in the regulation of G protein-coupled receptor (GPCR) sequestration, cell migration, synapse formation and dendritic ...

A neurocomputational model of classical conditioning phenomena: a putative role for the hippocampal region in associative learning.

16 Apr 2009 Some existing models of hippocampal function simulate performance in classical conditioning tasks using the error backpropagation algorithm to guide learning (Gluck, M.A., and Myers, C.E., (1993). Hippocampal mediation of stimulus representation: a ...

Nicotine anxiogenic and rewarding effects are decreased in mice lacking beta-endorphin.

15 Apr 2009 The endogenous opioid system plays an important role in the behavioral effects of nicotine. Thus, micro-opioid receptor and the endogenous opioids derived from proenkephalin are involved in the central effects of nicotine. However, the role played ...

Corticotropin releasing factor (CRF) modulates fear-induced alterations in sleep in mice.

15 Apr 2009 Contextual fear significantly reduces rapid eye movement sleep (REM) during post-exposure sleep in mice and rats. Corticotropin releasing factor (CRF) plays a major role in CNS responses to stressors. We examined the influence of CRF and astressin ...

Approach memory turns to avoidance memory with age.

9 Apr 2009 Ontogenetic modification of an early memory is relatively poorly understood. And an important question is whether the memory output is more determined by the age at acquisition or at retention? Here we explore the expression of odor-shock ...

Region specific gene expression profile in mouse brain after chronic corticotropin releasing factor receptor 1 activation: the novel role for diazepam binding inhibitor in contextual fear conditioning.

7 Apr 2009 We have previously reported that repeated central administration of sub-anxiogenic doses of the corticotropin releasing factor 1 (CRF(1)) agonist Cortagine, termed "priming," elicits a phenotype of increased anxiety-like behaviors in the elevated ...

Effects of rimonabant on the reinstatement of nicotine-conditioned place preference by drug priming in rats.

6 Apr 2009 Drug addiction is a chronic disorder characterized by a relatively high rate of relapse even after long period of abstinence. In the present study, we used the conditioned place preference (CPP) paradigm to investigate the establishment, extinction, ...
