  2. Hippocampus anatomy - Wikipedia

    en.wikipedia.org/wiki/Hippocampus_anatomy

    Hippocampus in the human brain Nissl-stained coronal section of the brain of a macaque monkey, showing hippocampal formation and subfields (circled). Hippocampus anatomy describes the physical aspects and properties of the hippocampus, a neural structure in the medial temporal lobe of each cerebral hemisphere of the brain.

  3. Hippocampus - Wikipedia

    en.wikipedia.org/wiki/Hippocampus

    The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus , and the subiculum are components of the hippocampal formation located in the limbic system .

  4. Dentate gyrus - Wikipedia

    en.wikipedia.org/wiki/Dentate_gyrus

    The dentate gyrus (DG) is one of the subfields of the hippocampus, in the hippocampal formation.The hippocampal formation is located in the temporal lobe of the brain, and includes the hippocampus (including CA1 to CA4) subfields, and other subfields including the dentate gyrus, subiculum, and presubiculum.

  5. Hippocampal subfields - Wikipedia

    en.wikipedia.org/wiki/Hippocampal_subfields

    The hippocampal subfields are four subfields CA1, CA2, CA3, and CA4 that make up the structure of the hippocampus.Regions described in the hippocampus are the head, body, and tail, and other hippocampal subfields include the dentate gyrus, the presubiculum, and the subiculum.

  6. Hippocampal formation - Wikipedia

    en.wikipedia.org/wiki/Hippocampal_formation

    The hippocampal formation is a compound structure in the medial temporal lobe of the brain. It forms a c-shaped bulge on the floor of the inferior horn of the lateral ventricle. [1] Typically, the hippocampal formation is said to included the dentate gyrus, the hippocampus, and the subiculum. [2]

  7. Fornix (neuroanatomy) - Wikipedia

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

    'arch'; pl.: fornices) is a C-shaped bundle of nerve fibers in the brain that acts as the major output tract of the hippocampus. 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 ...

  8. Entorhinal cortex - Wikipedia

    en.wikipedia.org/wiki/Entorhinal_cortex

    View of left entorhinal cortex (red) from beneath the brain, with front of brain at top. Artist's rendering. The superficial layers – layers II and III – of EC project to the dentate gyrus and hippocampus: Layer II projects primarily to dentate gyrus and hippocampal region CA3; layer III projects primarily to hippocampal region CA1 and the subiculum.

  9. Subiculum - Wikipedia

    en.wikipedia.org/wiki/Subiculum

    The subicular complex receives input from CA1 and entorhinal cortical layer III pyramidal neurons and is the main output of the hippocampus proper. The pyramidal neurons send projections to the nucleus accumbens , septal nuclei , prefrontal cortex , lateral hypothalamus , nucleus reuniens , mammillary nuclei , entorhinal cortex and amygdala .
