The septal nuclei are located in this area. The septal nuclei are composed of medium-size neurons which are classified into dorsal, ventral, medial , and caudal groups. [ 1 ] The septal nuclei receive reciprocal connections from the olfactory bulb , hippocampus , amygdala , hypothalamus , midbrain , habenula , cingulate gyrus , and thalamus .
Septum Verum (true septum) is a region in the lower medial part of the telencephalon that separates the two cerebral hemispheres.. The human septum consists of two parts: the septum pellucidum (translucent septum), a thin membrane consisting of white matter and glial cells that separate the lateral ventricles, and the lower, precommisural septum verum, which consists of nuclei and grey matter.
The medial septal nucleus (MS) is one of the septal nuclei. Neurons in this nucleus give rise to the bulk of efferents from the septal nuclei. A major projection from the medial septal nucleus terminates in the hippocampal formation. [1] It plays a role in the generation of theta waves in the hippocampus. [2]
The septum pellucidum is located in the septal area in the midline of the brain between the two cerebral hemispheres. The septal area is also the location of the septal nuclei. It is attached to the lower part of the corpus callosum, the large collection of nerve fibers that connect the two cerebral hemispheres.
Fornix and septal nuclei; Subcortical areas: Septal nuclei; Amygdala; Nucleus accumbens; Diencephalic structures: Hypothalamus; Mammillary bodies; Anterior nuclei of thalamus; Other areas that have been included in the limbic system include the: Stria medullaris; Central gray and dorsal and ventral nuclei of Gudden
Part of the human brain, the basal forebrain structures are located in the forebrain to the front of and below the striatum.They include the ventral basal ganglia (including nucleus accumbens and ventral pallidum), nucleus basalis, diagonal band of Broca, substantia innominata, and the medial septal nucleus.
The medial forebrain bundle (MFB) is the location of the most frequently investigated brain stimulation reward sites, and it is composed of a complex bundle of axons projecting from the basal olfactory regions and the septal nuclei. [3]
While the stria terminalis carries information primarily from the corticomedial nuclei of the amygdala, the ventral amygdalofugal pathway carries output from the central and basolateral nuclei and delivers it to a number of targets; namely, the medial dorsal nucleus of the thalamus, the hypothalamus, the basal forebrain, the brainstem, septal ...
