Differential Purkinje cell simple spike activity and pausing behavior related to cerebellar modules.
The massive computational capacity of the cerebellar cortex is conveyed by Purkinje cells onto cerebellar and vestibular nuclei neurons through their GABAergic, inhibitory output. This implies that pauses in Purkinje cell simple spike activity are potentially instrumental in cerebellar information processing, but their occurrence and extent are still heavily debated. The cerebellar cortex, alth...
متن کاملOptogenetic Manipulation of Cerebellar Purkinje Cell Activity In Vivo
Purkinje cells (PCs) are the sole output neurons of the cerebellar cortex. Although their anatomical connections and physiological response properties have been extensively studied, the causal role of their activity in behavioral, cognitive and autonomic functions is still unclear because PC activity cannot be selectively controlled. Here we developed a novel technique using optogenetics for se...
متن کاملFGF14 modulates resurgent sodium current in mouse cerebellar Purkinje neurons
Rapid firing of cerebellar Purkinje neurons is facilitated in part by a voltage-gated Na(+) (NaV) 'resurgent' current, which allows renewed Na(+) influx during membrane repolarization. Resurgent current results from unbinding of a blocking particle that competes with normal channel inactivation. The underlying molecular components contributing to resurgent current have not been fully identified...
متن کاملOleuropein Attenuates Deltamethrin-induced Apoptosis in Rat Cerebellar Purkinje Neurons
Background: Deltamethrin (DM) is a synthetic pyrethroid insecticide that can elicit neurotoxicity, and lead to apoptosis. There is accumulating evidence that oleuropein (OE) has anti-apoptotic effect. This study aimed at determining the DM toxicity and anti-apoptotic effect of OE pretreatment in cerebellar Purkinje neurons. Materials and Methods: Rats were randomly divided into four groups a...
متن کاملFeedforward inhibition controls the spread of granule cell-induced Purkinje cell activity in the cerebellar cortex.
Synapses associated with the parallel fiber (pf) axons of cerebellar granule cells constitute the largest excitatory input onto Purkinje cells (PCs). Although most theories of cerebellar function assume these synapses produce an excitatory sequential "beamlike" activation of PCs, numerous physiological studies have failed to find such beams. Using a computer model of the cerebellar cortex we pr...
