Neurons are more susceptible to brain ischemia than the supporting glial cells, because neurons have higher energy demand, conduct an action potential, and produce glutamate, whereas glial cells lack those properties.
While basal ganglia, cerebellar purkinje cells, hippocampal, and neocortical cells are more vulnerable to transient ischemic attack (TIA), brainstem and thalamic reticular neurons are more vulnerable to prolonged ischemic attack (stroke proper) [REF].
