Resistance to change within heterogeneous response sequences.
29 Jun 2009 
Three experiments investigated how instrumental and Pavlovian contingencies contribute to resistance to change (RTC) in different ordinal response positions within heterogeneous response sequences in pigeons. RTC in the initial and terminal response ...

A developmental dissociation in compound summation following extinction.
29 Jun 2009 Recent studies suggest that extinction may involve different processes across development. The present study attempted to further clarify the nature of the processes involved in extinction of Pavlovian conditioned fear across development by ...

29 Jun 2009 During auditory fear conditioning, it is well established that lateral amygdala (LA) neurons potentiate their response to the tone conditioned stimulus, and that this potentiation is required for conditioned fear behavior. Conditioned tone responses ...

29 Jun 2009 The transcription factor Pax6 has been implicated in neocortical neurogenesis in vertebrates, including humans. Analyses of the role of Pax6 in layer formation and cognitive abilities have been hampered by perinatal lethality of Pax6 mutants. Here, ...

Requirement of central ghrelin signaling for alcohol reward.
27 Jun 2009 
The stomach-derived hormone ghrelin interacts with key CNS circuits regulating energy balance and body weight. Here we provide evidence that the central ghrelin signaling system is required for alcohol reward. Central ghrelin administration (to ...

Hippocampal CA3 output is crucial for ripple-associated reactivation and consolidation of memory.
23 Jun 2009 A widely held memory consolidation theory posits that memory of events and space is initially stored in the hippocampus (HPC) in a time-limited manner and is consolidated in the neocortex for permanent storage. Although posttraining HPC lesions ...

Amygdala inhibitory circuits and the control of fear memory.
23 Jun 2009 Classical fear conditioning is a powerful behavioral paradigm that is widely used to study the neuronal substrates of learning and memory. Previous studies have clearly identified the amygdala as a key brain structure for acquisition and storage of ...

Generalization of conditioned fear along a dimension of increasing fear intensity.
22 Jun 2009 The present study investigated the extent to which fear generalization in humans is determined by the amount of fear intensity in nonconditioned stimuli relative to a perceptually similar conditioned stimulus. Stimuli consisted of graded emotionally ...

22 Jun 2009 The role of adult brain neurogenesis (generating new neurons) in learning and memory appears to be quite firmly established in spite of some criticism and lack of understanding of what the new neurons serve the brain for. Also, the few experiments ...

DHPG activation of group 1 mGluRs in BLA enhances fear conditioning.
22 Jun 2009 Group 1 metabotropic glutamate receptors are known to play an important role in both synaptic plasticity and memory. We show that activating these receptors prior to fear conditioning by infusing the group 1 mGluR agonist, ...
