The division of the brain in front of the prosencephalon, consisting of the two olfactory lobes from which the olfactory nerves arise.
a center in the cerebral hemispheres that governs the sense of smell in lower animals; in humans it seems to mediate complex emotional behavior
Greek rhinion = nostril, and enkephalos = brain; hence, the part of the brain concerned with smell (relatively large in lower animals).
The part of the brain concerned in the sense of smell. It is the part of the brain first to become functional in phylogenetic development.
rhin (nose), enkephalos (brain).
(Gr. rhis, nose; enkephalos, brain): Parts of the brain concerned with olfactory function (reception and integration). In the narrow sense it refers to those parts directly involved with reception of olfactory stimuli only (olfactor y bulbs, tract, striae, anterior olfactory nucleus, part of the amygdala and the pyriform cortex).
the most ancient and primitive part of the brain; it is composed of both cortical and subcortical structures located on the medial, inferior surfaces of the cerebral hemispheres; the limbic system is involved in the processing of olfactory stimuli, emotions, and memory
In animal anatomy, the rhinencephalon is a part of the brain involved with olfaction.
