What is pretectal nuclei?
Pretectal nuclei are a group of interconnected cell clusters in the midbrain that play a role in various visual and pupillary reflexes. They receive input from the retina and project to other brain regions involved in controlling eye movements and pupil size. Dysfunction of the pretectal nuclei can lead to abnormalities in these reflexes.
What are the two main parts of the midbrain?
cerebral aqueduct which traversing the midbrain divides it into two main parts:Tectum (smaller dorsal part), which consists of = 2 superior and 2 inferior colliculi2 cerebral peduncles (larger ventral part), which consist of = crus cerebri + substantia nigra + tegmentum
What forms the anterior portion of the midbrain?
The cerebral peduncles and the optic tract form the anterior portion of the midbrain.
How are midbrain and oblogata connected?
Midbrain and Oblogata are connected at least via the internet. P.S. - The Midbrain serves as the audiovisual highway of the brain connected to the Medulla Oblongata by the Pons. Oblogata is the creative activities on MySpace, Facebook, Oblogata etc.
What are the subsections of the brainstem?
The midbrain, pons, and medulla oblongata.
What are extra-pyramidal centers?
premotor area of cerebral cortex (area 6)corpus striatum (caudate & lentiform nuclei)subthalamic nucleus (in subthalamus)red nucleus (in midbrain)substantia nigra (in midbrain)inferior olivary nucleus (in medulla)nuclei of reticular formation (in brainstem)
What is tectum and tegmentum?
Thetegmentumis the area of the medulla that contains the cranial nerve nuclei, the nuclei of the reticular formation, the ascending tracts, and two special nuclei, the inferior olivary nucleus and the dorsal column nuclei (dorsally)Thetectum:The dorsal part of the midbrain is seen to have four elevations, named the superior and inferior colliculi. The upper ones are the superior colliculi, and they are functionally part of the visual system, a center for visual reflexes. The lower ones are the inferior colliculi, and these are relay nuclei in the auditory pathway. These colliculi form the“tectum”(a less frequently used term for these colliculi is the quadrigeminal plate). The pineal, a glandular structure, hangs down from the back of the diencephalon and sits between the colliculi.

What are the afferent and efferent fibers for Pretectal nucleus of the midbrain?
It receives its afferent light impulses from the retina and occipital cortex.it gives efferents to the Edinger-Westphal nuclei of both sides.
What effect does activity of the nuerons in medial septal nuclei have?
The medial septal nuclei are located in the anteroventral cerebrum. They have reciprocal connections to other parts of the limbic system; the hippocampus, amygdala, hypothalamus, cingulate gyrus, and thalamus. They are also connected to the midbrain. What we know most about the medial septal nuclei is that they play an important role in reward and reinforcement. So, if the medial septal nuclei where stimulated, the brain would perceive a reward, a pleasurable sensation.
What are the three parts of the brainstem?
midbrain, pons, medulla oblongata
What gives rise to the midbrainand aqueduct of the midbrain?
MESENCEPHALON gives rise to the mid brain and aqueduct of the midbrain

What is the Icd-9 code for benign tumor of the midbrain
What forms the anterior portion of the midbrain?
The cerebral peduncles and the optic tract form the anterior portion of the midbrain.
What is the mesencephalon also called?
The midbrain
Does the midbrain include the thalamus and hypothalamus?
No
