Abstract
We use molecular genetic approaches to map the functional connectivity of a subpopulation of GABA-containing neurons, located in the lateral subdivision of the central amygdala (CEl), which express protein kinase C-δ (PKC-δ). Channelrhodopsin-2-assisted circuit mapping in amygdala slices and cell-...

Abstract
We show that neuronal activity in the lateral subdivision of the central amygdala (CEl) is required for fear acquisition, whereas conditioned fear responses are driven by output neurons in the medial subdivision (CEm). Functional circuit analysis revealed that inhibitory CEA microcircuits are highly...

Behavioural Processes (85)1 2010
Abstract
We have used two genetic lines of quail divergently selected on tonic immobility duration, a behavioural index of fear. These two lines differ in their behavioural response to some, but not all, fear-inducing situations. In the present study, we investigated the contribution of human intervention in...

Developmental Psychology (46)4 2010
Abstract
We tested 2 main hypotheses: first, that an early self-concept along with self-other differentiation is a universal precursor of prosocial behavior in 19-month-olds, and second, that the importance attached to relational socialization goals (SGs) concerning interpersonal responsiveness (obedience, p...

Abstract
These results show that the size of recovery is proportional to the size of the depression produced by CS-alone exposures regardless of whether they occurred before, after, or both before and after conditioning. The results are discussed in terms of some contemporary models of recovery and of the in...

Abstract
We studied the learning produced by simple exposures to a stimulus. Exposures depressed orienting and subsequent conditioned freezing in rats. A remotely preexposed conditioned stimulus (CS) conditioned better and overshadowed a novel CS more than a recently preexposed CS. Additional preexposures re...

Abstract
I compared intra-individual variation in an immobile aposematic behavior of the newt Cynops pyrrhogaster under different thermal gradients, using 40 animals from four populations. I found a negative relationship between ambient temperature and the frequency of performing this behavior, independent o...

Behavioral Neuroscience (124)3 2010
Abstract
We examined whether rat strain influences the effects of IL lesions on extinction. In Experiment 1, Sprague-Dawley (SD) or Long-Evans (LE) rats received a standard auditory fear conditioning procedure, which was followed by an extinction session; freezing served as the index of conditional fear. Our...

Abstract
We found that OFC lesions concomitantly alter BI and metabolism in the bed nucleus of stria terminalis (BNST) region and that individual differences in BNST activity predict BI. Thus it appears that an important function of the OFC in response to threat is to modulate the BNST, which may more direct...

Abstract
We then showed that the reduction in freezing resulting from either US habituation or CS extinction was context-specific (i.e., a change in context led to a renewal of the learned fear response; Experiment 2) and, furthermore, was attenuated when a pre-test shock was given (i.e., reinstatement of fe...

Abstract
We show that short-term memory is, unlike long-term memory, not context specific. During this short period after learning, behavioral memory can be updated in order to incorporate new contextual information. We found that, during this period, the cycloheximide retrograde amnesic effect can be revert...

We investigated the role of these thalamic targets in both unconditioned (i.e., fear responses to predatory threat) and conditioned (i.e., contextual responses to predator-related cues) defensive behaviors. During cat exposure, all experimental groups exhibited intense defensive responses with the a...

Abstract
We investigated whether spermidine and polyamine antagonists that selectively block the NR2B subunit at the NMDAr alter the extinction of contextual conditioned fear in male Wistar rats. The bilateral intra-hippocampal administration of exogenous spermidine (2 nmol/site) immediately after, but not 6...

In adulthood, isolation-reared mice exhibited significant reductions in context-specific, but not cue-spe...
