  2. Mammillary body - Wikipedia

    en.wikipedia.org/wiki/Mammillary_body

    Mammillary body atrophy is present in several other conditions, such as colloid cysts in the third ventricle, Alzheimer's disease, schizophrenia, heart failure, and sleep apnea. In spite of this the exact function of the mammillary bodies is still not clear. [7]

  3. Wernicke–Korsakoff syndrome - Wikipedia

    en.wikipedia.org/wiki/Wernicke–Korsakoff_syndrome

    Wernicke-Korsakoff syndrome in people with chronic alcohol use particularly is associated with atrophy/infarction of specific regions of the brain, especially the mammillary bodies. Other regions include the anterior region of the thalamus (accounting for amnesic symptoms), the medial dorsal thalamus, the basal forebrain , the median and dorsal ...

  4. Wernicke encephalopathy - Wikipedia

    en.wikipedia.org/wiki/Wernicke_encephalopathy

    Chronic cases can present the atrophy of the mammillary bodies. [55] In 1949, the idea that WE lesions are a result of a disruption to the blood-brain barrier was introduced. [53] Large proteins passing into the brain can put neurological tissue at risk of toxic effects.

  5. Korsakoff syndrome - Wikipedia

    en.wikipedia.org/wiki/Korsakoff_syndrome

    Korsakoff syndrome (KS) [1] is a disorder of the central nervous system characterized by amnesia, deficits in explicit memory, and confabulation.This neurological disorder is caused by a deficiency of thiamine (vitamin B 1) in the brain, and it is typically associated with and exacerbated by the prolonged, excessive ingestion of alcohol. [2]

  6. Colloid cyst - Wikipedia

    en.wikipedia.org/wiki/Colloid_cyst

    CT scan of a 1 cm colloid cyst. A colloid cyst is a non-malignant tumor in the brain. It consists of a gelatinous material contained within a membrane of epithelial tissue. It is almost always found just posterior to the foramen of Monro in the anterior aspect of the third ventricle, originating from the roof of the ventricle.

  7. Mammillothalamic tract - Wikipedia

    en.wikipedia.org/wiki/Mammillothalamic_tract

    The mammillary bodies directly or indirectly connect to the amygdala, hippocampus, and thalami as major structures in the limbic system. [6] The mammillothalamic tract carries signals from the mammillary bodies via the anterior thalamus to support spatial memory .

  8. Tuber cinereum - Wikipedia

    en.wikipedia.org/wiki/Tuber_cinereum

    The tuber cinereum is a convex mass of grey matter, [3]: 495 a ventral/inferior distention of the hypothalamus forming the floor of the third ventricle. [citation needed] The portion of the tuber cinerum at the base of the infundibulum (pituitary stalk) is the median eminence; [2] the infundibulum extends ventrally/inferiorly from the median eminence to become continuous with the infundibulum.

  9. Hippocampus - Wikipedia

    en.wikipedia.org/wiki/Hippocampus

    A major output goes via the fornix to the lateral septal area and to the mammillary body of the hypothalamus (which the fornix interconnects with the hippocampus). [21] The hippocampus receives modulatory input from the serotonin , norepinephrine , and dopamine systems, and from the nucleus reuniens of the thalamus to field CA1.
