The APP-interacting protein FE65 is required for hippocampus-dependent learning and long-term potentiation.

25 Aug 2009 FE65 is expressed predominantly in the brain and interacts with the C-terminal domain of beta-amyloid precursor protein (APP). We examined hippocampus-dependent memory and in vivo long-term potentiation (LTP) at the CA1 synapses with ...

Inactivation of the infralimbic but not the prelimbic cortex impairs consolidation and retrieval of fear extinction.

23 Aug 2009 Rats were subjected to one or two cycles of context fear conditioning and extinction to study the roles of the prelimbic cortex (PL) and infralimbic cortex (IL) in learning and relearning to inhibit fear responses. Inactivation of the PL depressed ...

Simultaneous but not independent anisomycin infusions in insular cortex and amygdala hinder stabilization of taste memory when updated.

23 Aug 2009 Reconsolidation has been described as a process where a consolidated memory returns to a labile state when retrieved. Growing evidence suggests that reconsolidation is, in fact, a destabilization/stabilization process that incorporates updated ...

4'-Demethylnobiletin, a bioactive metabolite of nobiletin enhancing PKA/ERK/CREB signaling, rescues learning impairment associated with NMDA receptor antagonism via stimulation of the ERK cascade.

16 Aug 2009 The biochemical and pharmacological activities of nobiletin, including neurotrophic and memory-enhancing action, in both in vitro and in vivo systems are well established. However, whether its metabolites do have such beneficial effects like ...

Stress, genotype and norepinephrine in the prediction of mouse behavior using reinforcement learning.

14 Aug 2009 Individual behavioral performance during learning is known to be affected by modulatory factors, such as stress and motivation, and by genetic predispositions that influence sensitivity to these factors. Despite numerous studies, no integrative ...

TrkB modulates fear learning and amygdalar synaptic plasticity by specific docking sites.

10 Aug 2009 Understanding the modulation of the neural circuitry of fear is clearly one of the most important aims in neurobiology. Protein phosphorylation in response to external stimuli is considered a major mechanism underlying dynamic changes in neural ...

Involvement of nitric oxide synthesis in sensitization to the rewarding effects of morphine.

9 Aug 2009 Knowledge about the specific brain changes and neural plasticity processes produced by repeated exposure to a drug is essential to progress in the field of neurobiology of addiction and the development of effective medication. In the present study, ...

M1 receptors mediate cholinergic modulation of excitability in neocortical pyramidal neurons.

3 Aug 2009 ACh release into the rodent prefrontal cortex is predictive of successful performance of cue detection tasks, yet the cellular mechanisms underlying cholinergic modulation of cortical function are not fully understood. Prolonged ("tonic") muscarinic ...

Cornering the fear engram: long-term synaptic changes in the lateral nucleus of the amygdala after fear conditioning.

3 Aug 2009 Use-dependent synaptic modifications in the lateral nucleus of the amygdala (LA) have been suggested to be the cellular analog of memory trace after pavlovian fear conditioning. However, whether neurophysiological changes in the LA are produced as a ...

Roles of octopaminergic and dopaminergic neurons in appetitive and aversive memory recall in an insect.

2 Aug 2009 BACKGROUND: In insect classical conditioning, octopamine (the invertebrate counterpart of noradrenaline) or dopamine has been suggested to mediate reinforcing properties of appetitive or aversive unconditioned stimulus, respectively. However, the ...
