In animal anatomy, the rhinencephalon is a part of the brain involved with olfaction.

Components[edit]

The term rhinencephalon has been used to describe different structures at different points in time.^[1]

One definition includes the olfactory bulb, olfactory tract, anterior olfactory nucleus, anterior perforated substance, medial olfactory stria, lateral olfactory stria, parts of the amygdala and prepyriform area.^[2]

Some references classify other areas of the brain related to perception of smell as rhinencephalon, but areas of the human brain that receive fibers strictly from the olfactory bulb are limited to those of the paleopallium. As such, the rhinencephalon includes the olfactory bulb, the olfactory tract, the olfactory tubercle and striae, the anterior olfactory nucleus and parts of the amygdala and the piriform cortex.^{[clarification needed (see talk)]}

In different species[edit]

The development of the rhinencephalon varies among species. In humans it is rudimentary. A small area where the frontal lobe meets the temporal lobe and the area of cortex on the uncus of the parahipocampal gyrus (both belonging to the olfactory cortex) have a different structure (so called "allocortex") than most of the telencephalon and are phylogenetically older (so called paleocortex).^[3]

Although UDP-glucuronosyltransferases (UGTs) are important phase II drug-metabolizing enzymes, they are also involved in the metabolism of endogenous compounds. Certain substrates of UGTs, such as serotonin and estradiol, play important roles in the brain. However, the expression of UGTs in the huma

A prominent feature of the developing mammalian brain is the widespread migration of neural progenitor (NP) cells during embryogenesis. A striking example is provided by NP cells born in the ventral forebrain of mid-gestation stage mice, which subsequently migrate long distances to their final posit
