  2. Cerebrum - Wikipedia

    en.wikipedia.org/wiki/Cerebrum

    In humans, the cerebrum is the largest and best-developed of the five major divisions of the brain. The cerebrum is made up of the two cerebral hemispheres and their cerebral cortices (the outer layers of grey matter), and the underlying regions of white matter. [2] Its subcortical structures include the hippocampus, basal ganglia and olfactory ...

    Cerebral peduncle. Crus cerebri; Mesencephalic cranial nerve nuclei. Oculomotor nucleus (III) Edinger-Westphal nucleus; Trochlear nucleus (IV) Mesencephalic duct (cerebral aqueduct, aqueduct of Sylvius)

  4. Midbrain - Wikipedia

    en.wikipedia.org/wiki/Midbrain

    The corpora quadrigemina are four mounds, called colliculi, in two pairs – a superior and an inferior pair, on the surface of the tectum. The superior colliculi process some visual information, aid the decussation of several fibres of the optic nerve (some fibres remain ipsilateral), and are involved with saccadic eye movements .

  5. Outline of the human brain - Wikipedia

    Thalamocortical radiations – fibers between the thalamus and the cerebral cortex, associated with activity which causes symptoms associated with impulse control disorders, Parkinson's disease, attention deficit hyperactivity disorder, and other forms of chronic psychosis

  6. Brain - Wikipedia

    en.wikipedia.org/wiki/Brain

    The cerebral cortex is the part of the brain that most strongly distinguishes mammals. In non-mammalian vertebrates, the surface of the cerebrum is lined with a comparatively simple three-layered structure called the pallium. In mammals, the pallium evolves into a complex six-layered structure called neocortex or isocortex. [62]

    The outermost membrane of the cerebral cortex is the basement membrane of the pia mater called the glia limitans and is an important part of the blood–brain barrier. [12] In 2023 a fourth meningeal membrane has been proposed known as the subarachnoid lymphatic-like membrane .

  8. Cerebellar tentorium - Wikipedia

    en.wikipedia.org/wiki/Cerebellar_tentorium

    The free border of the tentorium is U-shaped; it forms an aperture - the tentorial notch (tentorial incisure) - which gives passage to the midbrain.The free border of each side extends anteriorly beyond the medial end of the superior petrosal sinus (i.e. the apex of the petrous part of the temporal bone [citation needed]) to overlap the attached margin, thenceforth forming a ridge of dura ...

  9. Lobes of the brain - Wikipedia

    en.wikipedia.org/wiki/Lobes_of_the_brain

    The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral sulcus, also called the Sylvian fissure.
