  2. Hippocampus proper - Wikipedia

    en.wikipedia.org/wiki/Hippocampus_proper

    The polymorphic layer is often called the hilus or hilar region. [12] The neurons in the polymorphic layer, including mossy cells and GABAergic interneurons, primarily receive inputs from the granule cells in the dentate gyrus in the form of mossy fibers and project to the inner molecular layer of the dentate gyrus via the associational ...

    Neuroimaging pictures can show a number of different shapes, depending on the angle and location of the cut. Shape of human hippocampus and associated structures Topologically, the surface of a cerebral hemisphere can be regarded as a sphere with an indentation where it attaches to the midbrain.

  4. Periaqueductal gray - Wikipedia

    en.wikipedia.org/wiki/Periaqueductal_gray

    The periaqueductal gray (PAG), also known as the central gray, is a brain region that plays a critical role in autonomic function, motivated behavior and behavioural responses to threatening stimuli. [1] [2] PAG is also the primary control center for descending pain modulation. It has enkephalin-producing cells that suppress pain.

  6. Dentate gyrus - Wikipedia

    en.wikipedia.org/wiki/Dentate_gyrus

    The dentate gyrus (DG) is part of the hippocampal formation in the temporal lobe of the brain, which also includes the hippocampus and the subiculum.The dentate gyrus is part of the hippocampal trisynaptic circuit and is thought to contribute to the formation of new episodic memories, [1] [2] the spontaneous exploration of novel environments [2] and other functions.

    Image 2: Cross-section of cerebral hemisphere showing structure and location of hippocampus Image 3: Coronal section of the brain of a macaque monkey, showing hippocampus (circled) The hippocampus can be seen as a ridge of gray matter tissue, elevating from the floor of each lateral ventricle in the region of the inferior or temporal horn.

  8. Parahippocampal gyrus - Wikipedia

    en.wikipedia.org/wiki/Parahippocampal_gyrus

    The parahippocampal gyrus (or hippocampal gyrus [1]) is a grey matter cortical region of the brain that surrounds the hippocampus and is part of the limbic system. The region plays an important role in memory encoding and retrieval. It has been involved in some cases of hippocampal sclerosis. [2] Asymmetry has been observed in schizophrenia. [3]

  9. Perirhinal cortex - Wikipedia

    en.wikipedia.org/wiki/Perirhinal_cortex

    The perirhinal cortex is involved in both visual perception and memory; [1] it facilitates the recognition and identification of environmental stimuli. Lesions to the perirhinal cortex in both monkeys and rats lead to the impairment of visual recognition memory, disrupting stimulus-stimulus associations and object-recognition abilities.
