  Rhinencephalon - Wikipedia, the free encyclopedia
In animal anatomy, the rhinencephalon is a part of the brain involved with olfaction.
Some references classify other areas of the brain related to perception of smell as rhinencephalon, but the areas of human brains 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.

The anterior extremity of the hippocampal gyrus is recurved in the form of a hook (uncus), which is separated from the apex of the temporal lobe by a slight fissure, the incisura temporalis.
—The rhinencephalon comprises the olfactory lobe, the uncus, the subcallosal and supracallosal gyri, the fascia dentata hippocampi, the septum pellucidum, the fornix, and the hippocampus.
The Olfactory Lobe (lobus olfactorius) is situated under the inferior or orbital surface of the frontal lobe.

Postsynaptic fibers from the anterior olfactory nucleus project along with the mitral and tufted cell axons to the rhinencephalon or via the anterior commisure to the contralateral anterior olfactory nucleus.

The aim of this study was anatomical and comparative examination of arterial vascularization of the rhinencephalon in man and in macrosmatic mammals.
Contrary to the human rhinencephalon, strongly developed rhinencephalon in cat and sheep possesses its own separate arterial pattern composed of special arteries for each regions of paleocortex, supplying the olfactory bulb and lobe.
In the cat and sheep brains, the region corresponding to the human anterior perforated substance comprises the greater rhinencephalon surface.

They were thus regarded as a part of the rhinencephalon, but it is now recognized that they belong to the neopallium; the cingulate gyrus is therefore sometimes described as a part of the frontal lobe, and the hippocampal as a part of the temporal lobe.
The cingulate gyrus (gyrus cinguli; callosal convolution) is an arch-shaped convolution, lying in close relation to the superficial surface of the corpus callosum, from which it is separated by a slit-like fissure, the callosal fissure.

The anterior part of the gyrus hippocampi and the cygus cinguli and most of the uncinate gyrus seem to be concerned in the senses of taste and smell.
Other parts of the rhinencephalon appear to be more efficient in initiating reflex actions than in arousing sensations in consciousness.
The intimate relationship of the primitive olfactory cortex to the rest of the cerebrum has never been altogether abrogated There are found fibers associating the different parts of the rhinencephalon with almost or quite all of the primary and overflow areas of the cortex.

 Tool Module: Three Major Social Theories
According to MacLean, the rhinencephalon, an older part of the cortex involved in the sense of smell, also played a central role in the emotions.
This theory was supported by the fact that the rhinencephalon had substantial connections with the hypothalamus and was still relatively large in human beings, even though the human sense of smell has largely atrophied compared with that of other species.
Having found that stimulating the rhinencephalon produced visceral responses similar to those caused by emotions, MacLean identified it as the "centre" of the emotions.

 The olfactory bulb, the limbic system and the influence of smell on the physiology of man.
The limbic system represents the hippocampus, fornic, cingulate gyrus, thalamus, mamillary bodies, amygdala and olfactory bulb, and although this might sound far too technical to be interesting, it is fascinating how the sense of smell actually happens and the effect it has on us all.
Before the term "limbic system" was used, the system was referred to as the rhinencephalon or "smell brain" and is considered as one of the oldest systems in the human body.
When a smell enters the nasal cavity, it meets up with over 50,000,000 receptor neurons which are located in the upper part of the nose and nasal septum, and the receptors are specialized in such a way that certain react to certain smells.

 Nat' Academies Press, Discovering the Brain (1992)
This system is a fairly old part of the brain and one that humans share with many other vertebrates; in reptiles, it is known as the rhinencephalon, or “smellbrain,” because it reacts primarily to signals of odor.
The limbic system is responsible for most of the basic drives and emotions and the associated involuntary behavior that are important for an animal's survival: pain and pleasure, fear, anger, sexual feelings, and even docility and affection.
As with the rhinencephalon, the sense of smell is a powerful factor.

 [No title]
Texts on brain evolution (46) and even Freud (cited in 27) have argued that, since humans raised their noses from the ground in the ascent to bipedalism, olfaction has lost its importance in affecting human behavior.
It is little wonder that researchers believe that smell no longer lives in the rhinencephalon or the rest of the human brain.
The hypotheses that suggest the vestigial place of odor and the "untenated rhinencephalon" must be re-evaluated in light of the many odor effects on human behavior and certainly the recent data showing odor effects on conditioning, brain activity, and possibly mate selection.

We investigated the effect of long-term GT-catechin intake on aging and oxidative damage using aged mice with accelerated senescence (SAMP10), a model of brain senescence with cerebral atrophy and cognitive dysfunction.
Major atrophy was observed in the rhinencephalon, hippocampus and striatum of 12-month-old untreated SAMP10 mice.
A preventive effect of GT-catechin intake on oxidative DNA damage was also observed in the rhinencephalon (an area particularly susceptible to atrophy) at 6 months of age, i.e.

The second set of pathways in and out of the cortex pass through two adjacent regions of modified cortical sheet called the archicortex and paleocortex that flank the six-layered neocortex (Sarnat and Netsky 1981).
Paleocortex lies below the necks of the balloons and contains the rhinencephalon (nose brain), where smell information enters; it connects with other regions thought to be concerned with mood and EMOTION.
Archicortex developed into the HIPPOCAMPUS, and is thought to be concerned with the laying down of memories.

The connections among these systems are well preserved among mammals.

Its cerebral structures encircle the upper apart of the brain stem and include parts of the rhinencephalon (the septal nuclei, cingulate gyrus, parahippocampal gyrus, and C-shaped hippocampus), and part of the amygdala.
The observation that odors often evoke emotional reactions and memories reflects the origin of much of this system in the "smell brain" (rhinencephalon).
Extensive connections between the limbic system and lower and higher brain regions allow the system to integrate and respond to a wide variety of environmental stimuli.

The telencephalon in front grows out secondarily to an extent progressively increasing in the higher groups and forms the corpora striata, the cerebral lobes and the rhinencephalon.
