PGO spikes travel which of the following pathways?
A) from the pons to the hypothalamus to the occipital cortex

Question

Quizplus · Accepted Answer

PGO (Pons-Geniculate-Occipital) spikes are a neural activity pattern that occurs during rapid eye movement (REM) sleep. The spikes originate in the pons and travel to the thalamus, which then projects to the occipital cortex to produce visual imagery during dreams. Therefore, the correct pathway is from the pons to the thalamus to the occipital cortex, as described in option B.
