Limbic system

The epithalamus is a (dorsal) posterior segment of the diencephalon.

The amygdalae (singular: amygdala; /əˈmɪɡdələ/; also corpus amygdaloideum; Latin, from Greek ἀμυγδαλή, amygdalē, 'almond', 'tonsil') are two almond-shaped groups of nuclei located deep and medially within the temporal lobes of the brain in complex vertebrates, including humans.

The hypothalamus (from Greek ὑπό, "under" and θάλαμος, thalamus) is a portion of the brain that contains a number of small nuclei with a variety of functions.

The hippocampal formation is a compound structure in the medial temporal lobe of the brain.

The nucleus accumbens (NAc or NAcc), also known as the accumbens nucleus or as the nucleus accumbens septi (Latin for nucleus adjacent to the septum) is a region in the basal forebrain rostral to the preoptic area of the hypothalamus.

The entorhinal cortex (EC) (ento = interior, rhino = nose, entorhinal = interior to the rhinal sulcus) is an area of the brain located in the medial temporal lobe and functioning as a hub in a widespread network for memory and navigation.

The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes in the brain which is involved in the cognitive processing of decision-making.

Hunger and satiety are sensations.

The mammillary bodies are a pair of small round bodies, located on the undersurface of the brain that, as part of the diencephalon, form part of the limbic system.

The islands of Calleja (IC, ISC, or IClj) are a group of neural granule cells located within the ventral striatum in the brains of most animals.

The central nucleus of the amygdala (CeA or aCeN) is a nucleus within the amygdala.

The hippocampus (named after its resemblance to the seahorse, from the Greek ἱππόκαμπος, "seahorse" from ἵππος hippos, "horse" and κάμπος kampos, "sea monster") is a major component of the brains of humans and other vertebrates.

The olfactory bulb (bulbus olfactorius) is a neural structure of the vertebrate forebrain involved in olfaction, or the sense of smell.

The sexually dimorphic nucleus (SDN) is an ovoid, densely packed cluster of large cells located in the medial preoptic area (POA) of the hypothalamus which is believed to be related to sexual behavior in animals.

In neuroanatomy, the cingulum is a collection of white matter fibers projecting from the cingulate gyrus to the entorhinal cortex in the brain, allowing for communication between components of the limbic system.

The septal nuclei (medial olfactory area) are a set of structures that lie below the rostrum of the corpus callosum, anterior to the lamina terminalis (the layer of gray matter in the brain connecting the optic chiasma and the anterior commissure where the latter becomes continuous with the rostral lamina).

The ventral striatum receives direct input from multiple regions in the cerebral cortex and limbic structures such as the amygdala, thalamus, and hippocampus, as well as the entorhinal cortex and the inferior temporal gyrus.

The Papez circuit (or medial limbic circuit), is a neural circuit for the control of emotional expression.

The Perirhinal cortex is a cortical region in the medial temporal lobe that is made up of Brodmann areas 35 and 36.

The lateral hypothalamus, also called the lateral hypothalamic area, contains the primary orexinergic nucleus within the hypothalamus that widely projects throughout the nervous system; this system of neurons mediates an array of cognitive and physical processes, such as promoting feeding behavior and arousal, reducing pain perception, and regulating body temperature, digestive functions, and blood pressure, among many others.

The mammillothalamic fasciculus (mammillothalamic tract, thalamomammillary fasciculus, bundle of Vicq d’Azyr) arises from cells in both the medial and lateral nuclei of the mammillary body and by fibers that are directly continued from the fornix.

Sommer's Sector is region CA1 of the hippocampus, a part of the human brain.
