What is the function of the complex of basal prosencephalic nuclei (medial septal and basal nuclei of Meynert)?
I - It provides Ach to the hippocampus and neocortex.
II - It controls neuronal excitability during alertness, wakefulness, and sleep cycles.

A função do complexo de núcleos prosencefálicos basais (núcleos septal medial e núcleos basais de Meynert) é fornecer acetilcolina (Ach) ao hipocampo e neocórtex, além de controlar a excitabilidade neuronal durante os ciclos de alerta, vigília e sono. A destruição desses núcleos resulta em distúrbios do sono, com despertares noturnos e sonolência diurna. Portanto, a alternativa correta é a letra D) I, II e III estão corretas.
