The septal nuclei receive reciprocal connections from the olfactory bulb, hippocampus, amygdala, hypothalamus, midbrain, habenula, cingulate gyrus, and thalamus. The septal nuclei play a role in reward and reinforcement along with the nucleus accumbens
septum pel·lu·ci·dum. n. pl. septa pel·lu·ci·da (-də). A thin membrane of nervous tissue that forms the medial wall of the lateral ventricles in the brain. Also called septum lucidum. atrioventricular septum the part of the membranous portion of the interventricular septum between the left ventricle and the right atrium. deviated septum an injury or malformation of the nasal septum so that one part of the nasal cavity is smaller than the other; this is fairly common and seldom causes complications. It is composed of a dorsal septal nucleus [TA], lateral septal nucleus [TA], medial septal nucleus [TA], septofimbrial nucleus [TA], and triangular nucleus of septum [TA]. The subformical organ [TA] is also found in this area. The definition information for septal area is provided by Stedman's.  The septal nuclei receive reciprocal connections from the olfactory bulb, hippocampus, amygdala, hypothalamus, midbrain, habenula, cingulate gyrus, and thalamus. The septal area (medial olfactory area) has no relation to the sense of smell, but it is considered a pleasure zone in animals. The septal nuclei play a role in reward and reinforcement along with the nucleus accumbens. In the 1950s, Olds & Milner showed that rats with electrodes implanted in this area will self-stimulate repeatedly (i.e. press a bar to receive electrical current that will stimulate the neurons). Cells located in the intermediolateral septum also project through the lateral part of the fimbria to all CA fields of the ventral hippocampus and adjacent subicular and entorhinal cortices. These cells also send fibers through the stria medullaris to the lateral habenular nucleus and mediodorsal thalamic nucleus. The hippocampus receives an extensive cholinergic input from the medial septal nucleus that ramifies throughout all layers and plays a pivotal modulatory role in cognitive function. the medial septal nucleus, nucleus of diagonal band of Broca, magnocellular preoptic nucleus and substantia innominata. We report that cholinergic cell loss in the medial septal nucleus and ventral diagonal band after i.c.v. The present data also demonstrate the presence of a medial septal nucleus that is histochemically comparable to the medial septum of mammals. The brain is the most important organ in your body because it controls everything in your body. It can be seen as supersense or sensory motor. The brain controls the functio … ning of the body electrical impulses. brain sends messages to the organ that wants to work at that time. its function is to control the body. The septum is a partition which divides the heart into left and right. The right side gets all the impure blood from the body and this is pumped out to the lungs where it gets … oxygenated or purified. This blood then returns to the left side of the heart and is then pumped out to supply the tissues Phylogenetically, the limbic system is one of the more primitive parts of the brain. It has a central role in memory, learning, emotion, neuroendocrine function, and autonomic activities. Clinical conditions involving the limbic system include epilepsy, congenital syndromes, dementias, and various psychiatric disorders. Hippocampus. The hippocampus is a part of the middle arc of the limbic sys tem. It is located in the medial temporal lobe inferior to the choroidal fissure and temporal horn. In the sagittal plane the hippocampus is a club-shaped structure divided into three parts: head, body, and tail. It is composed of a dorsal septal nucleus [TA], lateral septal nucleus [TA], medial septal nucleus [TA], septofimbrial nucleus [TA], and triangular nucleus of septum [TA]. The subformical organ [TA] is also found in this area. 1  Facebook.  Structure [edit]. The septum pellucidum is located in the midline of the brain, between the two cerebral hemispheres. It is attached superiorly to the corpus callosum, the large collection of nerve fibers that connect the two cerebral hemispheres.
