Neurobiology of Pavlovian fear conditioning.

- Biology, PsychologyAnnual review of neuroscience
Advances in neural circuits underlying fear conditioning have been mapped, synaptic plasticity in these circuits has been identified, and biochemical and genetic manipulations are beginning to unravel the molecular machinery responsible for the storage of fear memories.
The contextual brain: implications for fear conditioning, extinction and psychopathology
Studies of Pavlovian fear conditioning and extinction in rodents and humans suggest that a neural circuit including the hippocampus, amygdala and medial prefrontal cortex is involved in the learning and memory processes that enable context-dependent behaviour.
Neurotoxic lesions of the dorsal hippocampus and Pavlovian fear conditioning in rats
Neuronal signalling of fear memory
Recent electrophysiological studies indicating that neurons in the lateral amygdala encode aversive memories during the acquisition and extinction of Pavlovian fear conditioning provide evidence that theateral amygdala is a crucial locus of fear memory.

We have shown previously that electrolytic lesions of the dorsal hippocampus (DH) produce a severe deficit in contextual fear if made 1 d, but not 28 d, after fear conditioning (Kim and Fanselow,…
Contextual and auditory fear conditioning are mediated by the lateral, basal, and central amygdaloid nuclei in rats.
There is significant overlap within the amygdala in the neural pathways mediating fear conditioning to contextual and acoustic CS, and that these forms of learning are not anatomically dissociable at the level of amygdaloid nuclei.

Electrophysiological techniques are used to characterize neuronal transmission in axonal projections from the hippocampal formation to the basolateral amygdala in urethane-anesthetized rats, finding that the critical role of both structures in context conditioning implicates plasticity at HF-BLA synapses in this form of learning.
