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?
The two main parts of the midbrain are the tectum, which includes the superior and inferior colliculi involved in sensory processing, and the tegmentum, which includes nuclei involved in motor control and arousal.
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?
The tectum is the dorsal part of the midbrain and is involved in sensory processing and visual reflexes. The tegmentum is the ventral part of the midbrain and is involved in motor function, arousal, and attention.

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 forms the anterior portion of the midbrain?
The cerebral peduncles and the optic tract form the anterior portion of the midbrain.
