Anatomical terms of neuroanatomy. [edit on Wikidata] In neuroanatomy, the optic chiasm, or optic chiasma ( / ɒptɪk kaɪæzəm /; from Greek χίασμα 'crossing', from Ancient Greek χιάζω 'to mark with an X '), is the part of the brain where the optic nerves cross. It is located at the bottom of the brain immediately inferior to the ...
Trochlear nerve (cranial nerve 4) – eye rotation. Trigeminal nerve (cranial nerve 5) – sensation from the face and certain motor functions such as biting and chewing. Abducens nerve (cranial nerve 6) – certain eye rotation. Facial nerve (cranial nerve 7) – facial expression and taste sensations from the tongue.
The brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system.
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.
Interaction between dorsal and ventral attention networks enables dynamic control of attention in relation to top-down goals and bottom-up sensory stimulation. [1]The dorsal attention network (DAN), also known anatomically as the dorsal frontoparietal network (D-FPN), is a large-scale brain network of the human brain that is primarily composed of the intraparietal sulcus (IPS) and frontal eye ...
The cerebral cortex is the outer covering of the surfaces of the cerebral hemispheres and is folded into peaks called gyri, and grooves called sulci. In the human brain, it is between 2 and 3-4 mm. thick, [8] and makes up 40% of the brain's mass. [2] 90% of the cerebral cortex is the six-layered neocortex whilst the other 10% is made up of the ...
Anatomical terms of neuroanatomy. [edit on Wikidata] The longitudinal fissure (or cerebral fissure, great longitudinal fissure, median longitudinal fissure, interhemispheric fissure) is the deep groove that separates the two cerebral hemispheres of the vertebrate brain. Lying within it is a continuation of the dura mater (one of the meninges ...
Hippocampus. The hippocampus. The hippocampus is a structure in the brain that has been associated with various memory functions. It is part of the limbic system, and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn, and the Dentate gyrus, each containing different types of cells.
