The midbrain or mesencephalon is the rostral -most portion of the brainstem [ 2] connecting the diencephalon and cerebrum with the pons. [ 3] It consists of the cerebral peduncles, tegmentum, and tectum. It is functionally associated with vision, hearing, motor control, sleep and wakefulness, arousal ( alertness ), and temperature regulation.
The midbrain tegmentum is also an important part of the dopaminergic system which is essential for feelings of reward and pleasure. Two regions in the midbrain tegmentum are of particular interest. The first one is the substantia nigra which is an important part of the nigrostriatal pathway. This pathway serves to coordinate motor movements and ...
The brainstem (or brain stem) is the stalk-like part of the brain that connects the forebrain (the cerebrum and diencephalon) with the spinal cord. [ 1] In the human brain, the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [ 1][ 2] The midbrain is continuous with the thalamus of the diencephalon through the ...
The midbrain tegmentum is the part of the midbrain extending from the substantia nigra to the cerebral aqueduct in a horizontal section of the midbrain. Structures included in the midbrain tegmentum include the red nucleus, reticular formation, and substantia nigra. The red nucleus is responsible for controlling basic body and limb movements.
Anatomical terms of neuroanatomy. [ edit on Wikidata] In neuroanatomy, the superior colliculus (from Latin 'upper hill') is a structure lying on the roof of the mammalian midbrain. [ 1] In non-mammalian vertebrates, the homologous structure is known as the optic tectum or optic lobe. [ 1][ 2][ 3] The adjective form tectal is commonly used for ...
Anatomical terms of neuroanatomy. [ edit on Wikidata] The ventral tegmental area ( VTA) ( tegmentum is Latin for covering ), also known as the ventral tegmental area of Tsai, [ 1] or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain. The VTA is the origin of the dopaminergic cell bodies of ...
The cerebral aqueduct ( aqueduct of the midbrain, aqueduct of Sylvius, [ 1]: 476 sylvian aqueduct, mesencephalic duct[citation needed]) is a narrow [ 2][ 1]: 469 conduit for cerebrospinal fluid (CSF) connecting the third ventricle and fourth ventricle of the ventricular system of the brain. The cerebral aqueduct is a midline structure.
The inferior colliculus ( IC) ( Latin for lower hill) is the principal midbrain nucleus of the auditory pathway and receives input from several peripheral brainstem nuclei in the auditory pathway, as well as inputs from the auditory cortex. [ 1] The inferior colliculus has three subdivisions: the central nucleus, a dorsal cortex by which it is ...
