Cerebellar secretin modulates eyeblink classical conditioning.
We have previously shown that intracerebellar infusion of the neuropeptide secretin enhances the acquisition phase of eyeblink conditioning (EBC). Here, we sought to test whether endogenous secretin also regulates EBC and to test whether the effect of exogenous and endogenous secretin is specific to acquisition. In Experiment 1, rats received intracerebellar infusions of the secretin receptor a...
متن کاملCerebellar cortical inhibition and classical eyeblink conditioning.
The cerebellum is considered a brain structure in which memories for learned motor responses (e.g., conditioned eyeblink responses) are stored. Within the cerebellum, however, the relative importance of the cortex and the deep nuclei in motor learning/memory is not entirely clear. In this study, we show that the cerebellar cortex exerts both basal and stimulus-activated inhibition to the deep n...
متن کاملCerebellar norepinephrine modulates learning of delay classical eyeblink conditioning: evidence for post-synaptic signaling via PKA.
The neurotransmitter norepinephrine (NE) has been shown to modulate cerebellar-dependent learning and memory. Lesions of the nucleus locus coeruleus or systemic blockade of noradrenergic receptors has been shown to delay the acquisition of several cerebellar-dependent learning tasks. To date, no studies have shown a direct involvement of cerebellar noradrenergic activity nor localized the post-...
متن کاملCerebellar Involvement in Eyeblink Classical Conditioning in Humans
The role of the ipsilateral cerebellum in human eyeblink conditioning was investigated using the 400-ms delay paradigm and testing 14 cerebellar patients (7 with unilateral lesions and 7 with bilateral lesions) and 20 control participants. Patients performed significantly worse with the ipsilesional eye than control participants but showed no difference when tested with (he contralesional eye. ...
متن کاملCerebellar circuits and synaptic mechanisms involved in classical eyeblink conditioning.
There is increasing evidence that, in addition to its major functional role in the regulation of fine motor control, the cerebellum is involved in other important functions, such as sensory-motor learning and memory. Classical conditioning of the eyeblink or nictitating membrane response (and other discrete behavioral responses) is a form of sensory-motor learning that depends crucially upon th...
