What is the cingulate gyrus?
The cingulate gyrus is best appreciated while visualizing the medial aspect of either hemisphere of the cerebrum. It is a “C” shaped structure that is divided into a prelimbic and an infralimbic cortex, an anterior cingulate and a retrosplenial cortex. The cingulate cortex commences ventral to the rostrum of the corpus callosum, curves rostrally then follows the genu of the corpus callosum to progress posteriorly to blend with the precuneus of the parietal lobe. The cingulate gyrus is separated from the corpus callosum by the callosal sulcus (inferiorly) and from the medial frontal gyrus and paracentral lobule by the cingulate sulcus superiorly. The cingulate sulcus is continuous with the marginal sulcus, which separates the paracentral lobule from the precuneus. It is believed that the cingulate gyrus is strongly associated with the perception of neuropathic pain and nociception.
Where is the parahippocampal gyrus located?
The parahippocampal gyrus is more readily appreciated on the inferior surface of the temporal lobe of the cerebrum. It is located medial to the rhinal sulcus (an anterior continuation of the collateral sulcus) and the lateral occipitotemporal gyrus, lateral to the uncus, geniculate bodies and pulvinar of the thalamus, and anterior to the medial occipitotemporal gyrus. The area corresponds with several Brodmann areas such as the entorhinal cortex (area 27, 28), and areas 35, 36, 48 and 49. The parahippocampal gyrus provides a path of communication between the hippocampus and all cortical association areas through which afferent impulses enter the hippocampus.
How do the crura of the fornix communicate with each other?
It should be noted at this point where the crura of the fornix ascend posterior to the thalamus, they communicate with each other via the commissure of the fornix. The decussating fibers permit communication between the hippocampi of each side.

What Does the Limbic System Do?
The limbic system serves a variety of fundamental cognitive and emotional functions. The hippocampi, which lay on the inside edge of the temporal lobes, is essential to memory formation. The amygdalae sit on top of the front portion of each hippocampus. Each amygdala is thought to be important in processing emotion. The amygdala communicates closely with the hippocampus, which helps explain why we remember things that are more emotionally important. The amygdala also communicates closely with the hypothalamus, the area of the brain that is responsible for regulating temperature, appetite, and several other basic processes required for life. The hypothalamus itself is sometimes, but not always, included as part of the limbic system. Through the hypothalamus, as well as some key areas in the brainstem, the limbic system communicates with our autonomic nervous system (which regulates things like heartbeat and blood pressure), endocrine system, and the viscera (or “gut”).

What is paralimbic in psychology?
From there, however, opinions diverge as to what is considered part of the limbic system, and what is paralimbic, meaning a structure that interacts closely with the limbic system but is not truly part of it.
Which part of the brain is responsible for communicating with the hippocampus?
The hippocampus largely communicates through a large white matter pathway called the fornix , which curves around the ventricles of the brain towards the mammillary bodies, sending out branches to the mammillary bodies, thalamus, and cingulate along the way. The limbic system is a heterogeneous group of structures and serves many different functions.
Which part of the brain is considered paralimbic?
The basal forebrain, nucleus accumbens, mammillary bodies and parts of the thalamus (the anterior and mediodorsal nuclei) are also often considered paralimbic structures due to their close interaction with the limbic system. Each of these paralimbic structures has been connected with emotion or basic cognitive processes.

The limbic system is one hard-working region of the brain, as you can tell. Some specific limbic system functions include: Controlling emotions like anger and fear. Regulating eating, hunger and thirst. Responding to pain and pleasure.
Why is the limbic system important?
Because subparts of the limbic system ultimately regulate important aspects of our conscious and unconscious patterns — including our emotions, perceptions, relationships, behaviors and motor control — it’s easy to see why damage to this region can cause serious problems. Disorders or behaviors that are related to limbic system dysfunction, or sometimes limbic system damage due to things like traumatic injuries or aging, include: ( 4)
How does the limbic system affect the body?
One important way that the limbic system impacts emotional health is through carrying sensory input from the environment to the hypothalamus and then from the hypothalamus to other parts of the body. The hypothalamus acts like the “regulator” of hormone control, helps the body maintain homeostasis and send signals to the pituitary/thyroid/adrenal glands. It receives information from many body parts, including the heart, vagus nerve, gut/digestive system and skin.
How to maintain homeostasis in the limbic system?
In order to maintain homeostasis and feel your best, the goal is to balance activities of the parasympathetic and sympathetic nervous systems. Too much activation of one causes high amounts of anxiety, but too much of the other causes low motivation and symptoms like fatigue.
How does essential oil affect limbic function?
This is true because the strong fragrances they hold, which are found inside volatile molecules that can make their way into your bloodstream, travel directly through the blood/brain barrier very quickly.

The structures and interacting areas of the limbic system are involved in motivation, emotion, learning, and memory. The limbic system is where the subcortical structures meet the cerebral cortex. The limbic system operates by influencing the endocrine system and the autonomic nervous system. It is highly interconnected with the nucleus accumbens, which plays a role in sexual arousal and the "high" derived from certain recreational drugs. These responses are heavil…
Evolution
Paul D. MacLean, as part of his triune brain theory, hypothesized that the limbic system is older than other parts of the forebrain, and that it developed to manage circuitry attributed to the fight or flight first identified by Hans Selye in his report of the General Adaptation Syndrome in 1936. It may be considered a part of survival adaptation in reptiles as well as mammals (including humans). MacLean postulated that the human brain has evolved three components, that evolve…
