  2. Fornix (neuroanatomy) - Wikipedia

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

    The bundles of fibers come together in the midline of the brain, forming the body of the fornix. The lower edge of the septum pellucidum (the membrane that separates the lateral ventricles) is attached to the upper face of the fornix body. The body of the fornix travels anteriorly and divides again near the anterior commissure. The left and ...

  3. Corpus callosum - Wikipedia

    en.wikipedia.org/wiki/Corpus_callosum

    The corpus callosum (Latin for "tough body"), also callosal commissure, is a wide, thick nerve tract, consisting of a flat bundle of commissural fibers, beneath the cerebral cortex in the brain. The corpus callosum is only found in placental mammals . [ 1 ]

  4. Commissural fiber - Wikipedia

    en.wikipedia.org/wiki/Commissural_fiber

    The corpus callosum is essential to the communication between the two hemispheres. [2] A recent study of individuals with agenesis of the corpus callosum suggests that the corpus callosum plays a vital role in problem solving strategies, verbal processing speed, and executive performance. Specifically, the absence of a fully developed corpus ...

  5. Commissure - Wikipedia

    en.wikipedia.org/wiki/Commissure

    A commissure (/ ˈ k ɒ m ə ʃ ər /) is the location at which two objects abut or are joined. The term is used especially in the fields of anatomy and biology. The most common usage of the term refers to the brain's commissures, of which there are at least nine. Such a commissure is a bundle of commissural fibers as a tract that crosses the midline at i

  6. Septum pellucidum - Wikipedia

    en.wikipedia.org/wiki/Septum_pellucidum

    The septal area is also the location of the septal nuclei. It is attached to the lower part of the corpus callosum, the large collection of nerve fibers that connect the two cerebral hemispheres. It is attached to the front forward part of the fornix. The lateral ventricles sit on either side of the septum.

  7. Cave of septum pellucidum - Wikipedia

    en.wikipedia.org/wiki/Cave_of_septum_pellucidum

    The cave of septum pellucidum is bounded anteriorly by the genu of the corpus callosum, superiorly by the body of the corpus callosum, posteriorly by the anterior limb and pillars of the fornix, inferiorly by the anterior commissure and the rostrum of the corpus callosum, and laterally by the leaflets of the septum pellucidum. [6]

  8. Anterior commissure - Wikipedia

    en.wikipedia.org/wiki/Anterior_commissure

    In 1992, Laura Allen and Roger Gorski of UCLA measured the anterior commissures of 30 homosexual men, 30 heterosexual men, and 30 heterosexual women.They found that all three groups' commissures were significantly different from one another, with homosexual males having the largest anterior commissure, followed by heterosexual women, and then heterosexual men, who had the smallest anterior ...

  9. Hippocampus anatomy - Wikipedia

    en.wikipedia.org/wiki/Hippocampus_anatomy

    In the midline and under the corpus callosum, these fibers form the fornix. At the circuit level, the alveus contains axonal fibers from the DG and from Pyramidal neurons of CA3, CA2, CA1 and subiculum ( CA1 subiculum and CA1 entorhinal projections) that collect in the temporal hippocampus to form the fimbria/fornix, one of the major outputs of ...
