Over time, its damage can accumulate to create many issues, including neurodegenerative diseases like Alzheimer’s disease and mental health conditions like anxiety.
Hippocampal sclerosis occurs with severe CA1 and less severe CA3 and CA4 neuronal loss. [27] Experimental research has shown that N-methyl-d-aspartate (NMDA) receptor activation causes neuronal cell loss, and electrical stimulation-induced animal models of temporal lobe epilepsy duplicate the cell loss pattern of temporal lobe epilepsy in ...
