The lamina terminalis is a thin layer that forms the median portion of the wall of the forebrain.It stretches from the interventricular foramen (foramen of Monro) to the recess at the base of the optic stalk (optic nerve) and contains the vascular organ of the lamina terminalis, which regulates the osmotic concentration of the blood.
The median raphe nucleus (MRN), also known as the superior central nucleus, is a nucleus in the brainstem composed of polygonal, fusiform, and piriform neurons, which exists rostral to the pontine raphe nucleus. The median raphe nucleus is one of several raphe nuclei that lies on the brainstem midline. It is one of two nuclei that are situated ...
The median eminence is rich in fenestrated capillaries, allowing for the passage of proteins and neurohormones. More specifically, the median eminence allows for the transport of neurohormones between the CSF and the peripheral blood supply. [36] The major cell type that makes up the median eminence are specialized ependymal cells known as ...
The median eminence is generally defined as the portion of the ventral hypothalamus from which the portal vessels arise. [1] The median eminence is a small swelling on the tuber cinereum, posterior to and on top of the pituitary stalk; it lies in the area roughly bounded on its posterolateral region by the cerebral peduncles, and on its anterolateral region by the optic chiasm.
Image of the human brain showing sulci, gyri, and fundi shown in a Coronal section. Specific terms are used to represent the gross anatomy of the brain: A gyrus is an outward folding of the brain, for example the precentral gyrus. A sulcus is an inward fold, or valley in the brain's surface - for example the central sulcus. Additional terms ...
These nuclei interact with almost every pertinent portion of the brain, but only a few of them have specifically independent interaction. These select nuclei are discussed as follows. Overall, the caudal raphe nuclei, including the nucleus raphe magnus, nucleus raphe pallidus and nucleus raphe obscurus, all project towards the spinal cord and ...
An example of a skill requiring procedural memory would be playing a musical instrument, or driving a car or riding a bike. Individuals with transient global amnesia that have difficulty forming new memories and/or remembering old events may sometimes retain the ability to perform complex musical pieces, suggesting that procedural memory is ...
The human cerebellum is located at the base of the brain, with the large mass of the cerebrum above it, and the portion of the brainstem called the pons in front of it. It is separated from the overlying cerebrum by a layer of tough dura mater called the cerebellar tentorium; all of its connections with other parts of the brain travel through the pons.
