Vestibular responses in the macaque pedunculopontine nucleus and central mesencephalic reticular formation

Highlights ► The PPN and cMRF respond to vestibular (rotation/translation) stimuli. ► Visual pursuit responses are more frequent in the cMRF than in the PPN. ► Rotation preferences differ for the PPN (nose-down pitch) and cMRF (ipsilateral yaw). ► PPN translation response amplitudes are higher than...

Zusammenfassung:	Highlights ► The PPN and cMRF respond to vestibular (rotation/translation) stimuli. ► Visual pursuit responses are more frequent in the cMRF than in the PPN. ► Rotation preferences differ for the PPN (nose-down pitch) and cMRF (ipsilateral yaw). ► PPN translation response amplitudes are higher than those in the cMRF. ► The PPN and cMRF could initiate responses to vestibular stimuli like falls and turns.
