In hypoxic damage to the brain, which of the following is damaged most: (A) Claustrum, (B) Mamillary body, (C) Layer of corpus callosum, (D) Purkinje layer of cerebellum
Answer is B. The Cerebellar Cortex. The cerebellar cortex consists of three layers: the molecular layer, the granule cell layer and the Purkinje cell layer in the middle. The input to the cerebellum comes via the mossy fibers and via the climbing fibers.
Both of these are glutamatergic.
