Golgi cell dendrites are restricted by Purkinje cell stripe boundaries in the adult mouse cerebellar cortex.
Despite the general uniformity in cellular composition of the adult cerebellar cortex, there is a complex underlying pattern of parasagittal stripes of Purkinje cells with characteristic molecular phenotypes and patterns of connectivity. It is not known whether interneuron processes are restricted at stripe boundaries. To begin to address the issue, three strategies were used to explore how cer...
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...
متن کاملPurkinje Cell Collaterals Enable Output Signals from the Cerebellar Cortex to Feed Back to Purkinje Cells and Interneurons
Purkinje cells (PCs) provide the sole output from the cerebellar cortex. Although PCs are well characterized on many levels, surprisingly little is known about their axon collaterals and their target neurons within the cerebellar cortex. It has been proposed that PC collaterals transiently control circuit assembly in early development, but it is thought that PC-to-PC connections are subsequentl...
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 کاملThe community effect and Purkinje cell migration in the cerebellar cortex: analysis of scrambler chimeric mice.
The Disabled-1 protein in mouse is known to be an intercellular signaling component of the Reelin molecular pathway that subserves neuronal migration in several structures in the brain and spinal cord. The scrambler mutant mouse, which is phenotypically identical to the reeler mouse, is due to a mutation in the disabled-1 gene (Howell et al., 1997; Sheldon et al., 1997). The Purkinje cells of t...
