Anatomy. The brain is divided into supratentorial and infratentorial compartments by the tentorium cerebelli. The supratentorial compartment includes the cerebral hemispheres and the sellar, pineal, and diencephalic regions, whereas the infratentorial compartment includes the midbrain, pons, medulla, and cerebellum.

Answer and Explanation: Yes, the occipital lobe is supratentorial. Supratentorial is an anatomical position that refers to the area of the brain above the cerebellar tentorium.
Can brain lesions disappear?
Conclusions: Brainstem lesions in MS patients can disappear on subsequent imaging. Disappearing MRI lesions may delay the diagnosis. These results suggest that more weight should be given to the reported clinical brainstem events, especially in the initial diagnosis of MS. Disclosure: Dr.
What happens when the pons in the brain is damaged?
Paralysis (affects parts of your head, face, or specific parts of your body; extensive damage to the pons will cause paralysis to your entire body — other than your eye movement — in a condition known as locked-in syndrome).
What are the 3 functions of the pons?
The main functions of the pons include: It is involved in transferring information between the cerebellum and motor cortex. It controls the magnitude and frequency of the respiration. It is also involved in controlling the sleep cycles.
How does the pons affect behavior?
The pons is also involved in the control of sleep cycles and the regulation of deep sleep. The pons activates inhibitory centers in the medulla in order to inhibit movement during sleep. Another primary function of the pons is to connect the forebrain with the hindbrain.
Is the brain stem supratentorial?
The supratentorial area contains the cerebrum, lateral ventricle, third ventricle, choroid plexus, hypothalamus, pineal gland, pituitary gland, and optic nerve. The posterior fossa/infratentorial area contains the cerebellum, tectum, fourth ventricle, and brain stem (pons and medulla).
What is supratentorial craniotomy?
