cerebellar nuclei การใช้

• The fibers arise from the deep cerebellar nuclei.
• In deep cerebellar nuclei, calcium currents are not uniformly distributed along a dendrite.
• The cerebellar cortex projects to the deep cerebellar nuclei ( the corticonuclear microcomplex ).
• Neurons in the cerebellar nuclei generate spontaneous action potentials despite ongoing inhibition from Purkinje cells.
• Climbing fibers ultimately project to both the deep cerebellar nuclei and Purkinje cells ( PCs ) in the cerebellar cortex.
• The deep cerebellar nuclei receive the final output from the cerebellar cortex via Purkinje cells in the form of inhibition.
• The SCA supplies blood to most of the cerebellar cortex, the cerebellar nuclei, and the superior cerebellar peduncles.
• Most of the output from the cerebellum initially synapses onto the deep cerebellar nuclei before exiting via the three peduncles.
• Together, the deep cerebellar nuclei form a functional unit that provides feedback control of the cerebellar cortex by cerebellar output.
• One main objective of the treatment is to re-establish the physiological inhibition exerted by the cerebellar cortex over cerebellar nuclei.
• Also, the Purkinje cells belonging to a microzone all send their axons to the same small cluster of output cells within the deep cerebellar nuclei.
• The cerebellar nuclei receive afferent projections from the inferior olive, lateral reticular nucleus, upper cervical and lumbar spinal segments, and the Pontine nuclei.
• Other systems that may be involved in pattern generation and regulation are the pontine respiratory group, the lateral tegmental field and the deep cerebellar nuclei.
• These axons pass through the pons and enter the cerebellum via the inferior cerebellar peduncle where they form synapses with the deep cerebellar nuclei and Purkinje cells.
• It sends fibers to deep cerebellar nuclei that, in turn, project to both the cerebral cortex and the brain stem, thus providing modulation of descending motor systems.
• In addition to receiving converging CS and US input via the PN and IO, respectively, cells of the cerebellar nuclei receive GABA-ergic inhibitory input from PCs of the cerebellar cortex.
• It is one of the four deep cerebellar nuclei ( the others being the nucleus dentatus, nucleus emboliformis and nucleus globosus ), and is grey matter embedded in the white matter of the cerebellum.
• Embedded within the white matter which is sometimes called the " arbor vitae " ( Tree of Life ) in the cerebellum because of its branched, tree-like appearance are four deep cerebellar nuclei.
• The human spinal cord, visual pathway, cerebellar nuclei and the autonomic innervation of human urinary bladder have been studied to highlight the critical time periods during which these regions are susceptible to alterations in the micro-environment of the fetus that could result in related developmental abnormalities.
• The unusual surface appearance of the cerebellum conceals the fact that most of its volume is made up of a very tightly folded layer of arbor vitae " ( tree of life ) because of its branched, tree-like appearance in cross-section are four deep cerebellar nuclei, composed of gray matter.
