lateral mammillary nucleus | | Acronym(s) | mmb | | NeuroNames | hier-395 | | MeSH | Mamillary+Bodies | The mammillary bodies (mamillary bodies) are a pair of small round bodies, located on the undersurface of the brain, that form part of the limbic system. They are located at the ends of the anterior arches of the fornix. They consist of two groups of nuclei, the medial mammillary nuclei and the lateral mammillary nuclei.
Neuroanatomists have often categorized the mammillary bodies as part of the hypothalamus.[1] Image File history File links Gray1180. ...

Connections
They are connected to other parts of the brain (as shown in the schematic, below left), and act as a relay for impulses coming from the amygdalae and hippocampi, via the mamillo-thalamic tract to the thalamus. This article is about part of the human brain. ...

Function They are involved with the processing of recognition memory, along with the anterior and dorsomedial nuclei in the thalamus.
Pathology The mammillary bodies are parts of the brain known to be significantly damaged by alcohol intoxication, especially by chronic alcohol abuse and associated deficiency of thiamine. Researchers, in 1998, also noted visible abnormalities in the mammillary bodies of individuals with autism.[2] Ethyl alcohol, also known as ethanol or grain alcohol, is a flammable, colorless chemical compound, one of the alcohols that is most often found in alcoholic beverages. ...

Autism is a brain development disorder characterized by impairments in social interaction and communication, and restricted and repetitive behavior, all exhibited before a child is three years old. ...
Damage to the mammillary bodies due to thiamine deficiency is implied in pathogenesis of Wernicke-Korsakoff syndrome. Symptoms include impaired memory, also called anterograde amnesia, suggesting that the mammillary bodies may be important for memory. Lesions of the medial dorsal and anterior nuclei of the thalami and lesions of the mammillary bodies are commonly involved in amnesic syndromes in humans.[3] For the similarly spelled nucleic acid, see Thymine Thiamine or thiamin, also known as vitamin B1, is one of the B vitamins. ...
Wernicke-Korsakoff syndrome is a combination of Korsakoffs syndrome, which is characterized by confusion, severe anterograde and retrograde amnesia and confabulation; and Wernickes encephalopathy, which is characterized by nystagmus, ophthalmoplegia, coma and, if untreated, death. ...
