11 - Cerebellum and Basal Ganglia Lab Images Flashcards
What are the components of the basal ganglia? What are the structures in order from the insula inwards?
Where is the nucleus accumbens located?
Where is the white matter and grey matter of the cerebellum? How do afferent and efferent fibers pass to and from the brainstem?
The cortex is grey mayyer and the central core is white matter.
Afferent and efferent fibers pass to and from the brainstem via the inferior, middle, and superior cerebellar peduncles, linking the medulla, pons, and midbrain respectively.
What are the three layers of the cerebellar cortex? Which is the outer, middle, and inner most?
Molecular layer is the outermost that consists mainly of dendritic proceses from stellate and basket cells.
Purkinje cell layer is in the middle (large cells, layer one cell thick)
Granule layer is the deepest layer, with small round nuclei of granule cells and larger golgi cells.
Where do purkinje cells project?
They have branches that project into the cortex and terminate on cells within the deep cerebellar nuclei.
They are the only course of output from the cerebellar cortex.
Purkinje cells are inhibitory and project to the deep cerebellar nuclei.
