The only excitatory neurons in cerebellar
cortex are?
a) Purkinje
b) Basket
c) Golgi
d) Granule cells
Correct Answer - D
Ans. is’d’i.e., Granule cells [Ref BDC Vol. 3 p 92)
Purkinje cells are the only output cells from cerebellar cortex.
Purkinje cells send inhibitory efferents to deep cerebellar nuclei.
Basket cells inhibit body of purkinje cells while stellate cells inhibit
dendrites of purkinje cells.
Granule cells send facilitatory efferents to basket, stellate and
purkinje cells through parallel fibers.
Climbing fibers and parallel fibers stimulate purkinje cells.
