Caudate nucleus in retrieval of trace eyeblink conditioning after consolidation.
Trace eyeblink conditioning (EBC) is an associative learning task in which a stimulus-free trace period separates the presentation of a behaviorally neutral conditioned stimulus (CS; whisker stimulation) from a behaviorally salient unconditioned stimulus (US; air puff to the eye). Repeated pairings of the CS with the US results in the emergence of the conditioned response (CR; eyeblink after CS...
متن کاملCaudate nucleus is critically involved in trace eyeblink conditioning.
The basal ganglia are a collection of brain regions involved with motor planning and initiation. The major site of cortical and thalamic input into the basal ganglia network is the striatum, which includes a differentiated caudate nucleus (CN) and the putamen in rabbits. Trace eyeblink conditioning (EBC) is a forebrain-dependent associative learning task in which a stimulus-free time interval s...
متن کاملFunctional reorganization of a prefrontal cortical network mediating consolidation of trace eyeblink conditioning.
The medial prefrontal cortex (mPFC) has been studied for its role in various cognitive functions, but the roles of its subregions remain unclear. We performed tetrode recordings simultaneously from prelimbic (PL) and rostral (rACC) and caudal (cACC) anterior cingulate subregions of the rabbit mPFC to understand their interactions during learning and tests of remote memory retention for whisker-...
متن کاملOntogeny of delay versus trace eyeblink conditioning in the rat.
The ontogeny of delay versus trace eyeblink conditioning was examined in 19-, 23-, and 30-day-old rat pups. Pairings of a tone conditioned stimulus (CS) and periocular shock unconditioned stimulus (US; 100-ms) were presented in one of three conditioning paradigms: standard delay [380-ms CS, 280-ms interstimulus interval (ISI)], trace (380-ms CS, 500-ms trace interval), or long-delay (980-ms CS,...
متن کاملRole of hippocampal NMDA receptors in trace eyeblink conditioning.
We examined the effects of acute injections of competitive N-methyl-D-aspartate (NMDA) receptor antagonist 2-amino-5-phosphonovaleric acid (APV) into the dorsal hippocampus on contextual fear conditioning and classical eyeblink conditioning in C57BL/6 mice. When injected 10 to 40 min before training, APV severely impaired contextual fear conditioning. Thus, APV injection under these conditions ...
