  2. Brain morphometry - Wikipedia

    en.wikipedia.org/wiki/Brain_morphometry

    This allows researchers to quantify anatomical features of the brain in terms of shape, mass, volume (e.g. of the hippocampus, or of the primary versus secondary visual cortex), and to derive more specific information, such as the encephalization quotient, grey matter density and white matter connectivity, gyrification, cortical thickness, or ...

  3. Hippocampal memory encoding and retrieval - Wikipedia

    en.wikipedia.org/wiki/Hippocampal_memory...

    The hippocampus is located in the medial temporal lobe (subcortical), and is an infolding of the medial temporal cortex. [1] The hippocampus plays an important role in the transfer of information from short-term memory to long-term memory during encoding and retrieval stages. These stages do not need to occur successively, but are, as studies ...

  4. Leukocyte esterase - Wikipedia

    en.wikipedia.org/wiki/Leukocyte_esterase

    Leukocyte esterase (LE) is an esterase (a type of enzyme) produced by leukocytes (white blood cells). A leukocyte esterase test (LE test) is a urine test for the presence of white blood cells and other abnormalities associated with infection. White blood cells in the urine can indicate a urinary tract infection (UTI). Positive test results may ...

  5. 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 the components of the hippocampal formation located in the limbic system.

  6. White matter - Wikipedia

    en.wikipedia.org/wiki/White_matter

    White matter is the tissue through which messages pass between different areas of grey matter within the central nervous system. The white matter is white because of the fatty substance (myelin) that surrounds the nerve fibers (axons). This myelin is found in almost all long nerve fibers, and acts as an electrical insulation.

  7. Neuroimaging intelligence testing - Wikipedia

    en.wikipedia.org/wiki/Neuroimaging_intelligence...

    It is thought by some that grey and white matter specifically relate to different IQs (grey matter with Verbal IQ and white matter with Performance IQ), but the results have not been consistent. It has been found that within the cortex, the correlation with IQ was very influenced by the volume of prefrontal grey matter.

  8. 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. [3]

  9. Cingulum (brain) - Wikipedia

    en.wikipedia.org/wiki/Cingulum_(brain)

    Damage to the cingulum also simultaneously damages the hippocampus. This is vital because the hippocampus is pivotal in memory storage. Damage to gray matter, bodies of neurons, or white matter of axons in the cingulum therefore can affect humans cognitively because of this damage. Also variations in microstructure of a group of fibers in the ...
