  2. Thalamus - Wikipedia

    en.wikipedia.org/wiki/Thalamus

    The thalamus is a paired structure of gray matter about four centimetres long, located in the forebrain which is superior to the midbrain, near the center of the brain with nerve fibers projecting out to the cerebral cortex in all directions.

  3. Midbrain - Wikipedia

    en.wikipedia.org/wiki/Midbrain

    The midbrain or mesencephalon is the uppermost portion of the brainstem connecting the diencephalon and cerebrum with the pons. [2] 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.

  4. Lateral geniculate nucleus - Wikipedia

    en.wikipedia.org/wiki/Lateral_geniculate_nucleus

    In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway. It is a small, ovoid, ventral projection of the thalamus where the thalamus connects with the optic nerve. There are two LGNs, one on the ...

  6. Brainstem - Wikipedia

    en.wikipedia.org/wiki/Brainstem

    In the human brain the brainstem is composed of the midbrain, the pons, and the medulla oblongata. [1] The midbrain is continuous with the thalamus of the diencephalon through the tentorial notch, and sometimes the diencephalon is included in the brainstem. [2] The brainstem is very small, making up around only 2.6 percent of the brain's total ...

  7. Forebrain - Wikipedia

    en.wikipedia.org/wiki/Forebrain

    Vesicles of the forebrain (prosencephalon), the midbrain (mesencephalon), and hindbrain (rhombencephalon) are the three primary brain vesicles during the early development of the nervous system. At the five-vesicle stage, the forebrain separates into the diencephalon ( thalamus , hypothalamus , subthalamus , and epithalamus ) and the ...

  8. Limbic system - Wikipedia

    en.wikipedia.org/wiki/Limbic_system

    The limbic system, also known as the paleomammalian cortex, is a set of brain structures located on both sides of the thalamus, immediately beneath the medial temporal lobe of the cerebrum primarily in the forebrain. [1] Its various components support a variety of functions including emotion, behavior, long-term memory, and olfaction. [2]

  9. Anatomy of the cerebellum - Wikipedia

    en.wikipedia.org/wiki/Anatomy_of_the_cerebellum

    Thus, the superior cerebellar peduncle is the major output pathway of the cerebellum. Most of the efferent fibers originate within the dentate nucleus which in turn project to various midbrain structures including the red nucleus, the ventral lateral/ventral anterior nucleus of the thalamus, and the medulla.
