Conjunctive representations, the hippocampus, and contextual fear conditioning.
The context in which events occur can be represented as both (1) a set of independent features, the feature representation view, and (2) a set of features bound into a unitary representation, the conjunction representation view. It is assumed that extrahippocampal (e.g., neocortical) areas provide a basis for feature representations, but the hippocampal formation makes an essential contribution...
متن کاملHippocampus and contextual fear conditioning: recent controversies and advances.
Dorsal hippocampal (DH) lesions produce a severe deficit in recently, but not remotely, acquired contextual fear without impairing memory of discrete training stimuli, i.e., DH lesions produce an anterograde and time-limited retrograde amnesia specific to contextual memory. These data are consistent with the standard model which posits temporary involvement of the hippocampus in recent memory m...
متن کاملThe role of calsenilin/DREAM/KChIP3 in contextual fear conditioning.
Potassium channel interacting proteins (KChIPs) are members of a family of calcium binding proteins that interact with Kv4 potassium (K(+)) channel primary subunits and also act as transcription factors. The Kv4 subunit is a primary K(+) channel pore-forming subunit, which contributes to the somatic and dendritic A-type currents throughout the nervous system. These A-type currents play a key ro...
متن کاملContextual fear conditioning in zebrafish.
Zebrafish are a genetically tractable vertebrate that hold considerable promise for elucidating the molecular basis of behavior. Although numerous recent advances have been made in the ability to precisely manipulate the zebrafish genome, much less is known about many aspects of learning and memory in adult fish. Here, we describe the development of a contextual fear conditioning paradigm using...
متن کاملAmygdala regulation of immediate-early gene expression in the hippocampus induced by contextual fear conditioning.
The basolateral nuclei of the amygdala (BLA) are thought to modulate memory storage in other brain regions (McGaugh, 2004). We reported that BLA modulates the memory for both an explored context and for contextual fear conditioning. Both of these memories depend on the hippocampus. Here, we examined the hypothesis that the BLA exerts its modulatory effect by regulating the expression of immedia...
