Summary

Neurons are the fundamental information-processing cells of the nervous system, transmitting electrical and chemical signals across synapses. The human brain contains approximately 86 billion neurons organized into circuits for perception, cognition, and motor control. Key subtypes include excitatory glutamatergic pyramidal neurons, inhibitory GABAergic interneurons (parvalbumin+, somatostatin+, VIP+), dopaminergic neurons (substantia nigra, VTA), and cholinergic neurons (basal forebrain). Selective neuronal vulnerability is a hallmark of neurodegeneration: entorhinal cortex layer II neurons in AD, dopaminergic neurons in PD, motor neurons in ALS, and medium spiny neurons in HD. Neuronal loss correlates more strongly with cognitive decline than amyloid plaques, driving interest in neuroprotective strategies.
