  2. 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]

  3. Forebrain - Wikipedia

    en.wikipedia.org/wiki/Forebrain

    In humans, by 5 weeks in utero it is visible as a single portion toward the front of the fetus. At 8 weeks in utero, the forebrain splits into the left and right cerebral hemispheres. When the embryonic forebrain fails to divide the brain into two lobes, it results in a condition known as holoprosencephaly. The main structures of the forebrain ...

    Olfactory nerve (cranial nerve 1) – smell; Optic nerve (cranial nerve 2) – sight; Oculomotor nerve (cranial nerve 3) – eye movement (except rotation) Trochlear nerve (cranial nerve 4) – eye rotation; Trigeminal nerve (cranial nerve 5) – sensation from the face and certain motor functions such as biting and chewing

    [1] It contains both ascending and descending fibers. The mesolimbic pathway, which is a collection of dopaminergic neurons that projects from the ventral tegmental area to the nucleus accumbens, is a component pathway of the MFB. [2] The MFB is one of the two major pathways connecting the limbic forebrain, midbrain, and hindbrain.

  7. Fornix (neuroanatomy) - Wikipedia

    en.wikipedia.org/wiki/Fornix_(neuroanatomy)

    The fornix also carries some afferent fibers to the hippocampus from structures in the diencephalon and basal forebrain. The fornix is part of the limbic system . While its exact function and importance in the physiology of the brain are still not entirely clear, it has been demonstrated in humans that surgical transection—the cutting of the ...

  8. Brodmann area - Wikipedia

    en.wikipedia.org/wiki/Brodmann_area

    Many of the areas Brodmann defined based solely on their neuronal organization have since been correlated closely to diverse cortical functions. For example, Brodmann areas 1, 2 and 3 are the primary somatosensory cortex; area 4 is the primary motor cortex; area 17 is the primary visual cortex; and areas 41 and 42 correspond closely to primary ...

  9. Basal forebrain - Wikipedia

    en.wikipedia.org/wiki/Basal_forebrain

    The importance of non-cholinergic neurons in the basal forebrain structures has been shown in working together with the cholinergic neurons in a dynamically modulatory way. This is seen to play a significant role in cognitive functions. [2] Nitric oxide production in the basal forebrain is both necessary and sufficient to produce sleep. [5]
