Mammillary bodies, and their projections to the anterior thalamus via the mammillothalamic tract, are important for recollective memory. [7] According to studies of rats with mammillary body lesions, damage to the medial mammillary nucleus lead to spatial memory deficits.
The mammillothalamic tract is part of the Papez circuit (involved in spatial memory), starting and finishing in the hippocampus. [1] The fibers of the MMT are heavily myelinated. [2] [3] [4] It arises from the medial and lateral nuclei of the mammillary bodies, and from fibers that are directly continued from the fornix of the hippocampus.
The anterior nuclei receive afferents from the hippocampus and subiculum directly via the fornix, and indirectly via the mammillary bodies and mammillothalamic tract (MTT). They send efferent fibers to the cingulate gyrus, limbic, and orbitofrontal cortex. [1] The anterior nuclei of the thalamus display functions pertaining to memory.
Some scientists have narrowed it down to specifically spatial and episodic memory. [9] [10] Damage to the mammillothalamic tract, ventral anterior nucleus, and ventral lateral nucleus can result in memory and language impairment. [11] Amnesia can be a result of disconnection of the mammillary bodies from the Papez circuit. [12]
Memorials is an object which serves as a focus for the memory or the commemoration of something, usually an influential, deceased person or a historical, tragic event. Military funeral is a memorial or burial rite given by a country's military for a soldier , sailor , marine or airman who died in battle, a veteran , or other prominent military ...
The position of the burial looks at the body, the head, and the arms separately. The position could help researchers say something about the populations ideas of death as well as common burial practices. There are two positions the body can be placed in. First is the extended position, where the individual is laid flat.
Body snatching is the secret removal of corpses from burial sites. A common purpose of body snatching, especially in the 19th century, was to sell the corpses for dissection or anatomy lectures in medical schools. [1] Damnatio memoriae Latin phrase meaning "condemnation of memory", indicating that a person is to be excluded from official ...
People with the condition may also exhibit a dislike for sunlight and so may wish to stay indoors with the lights off. The mechanism of this degeneration is unknown, but it supports the current neurological theory that the mammillary bodies play a role in various "memory circuits" within the brain. An example of a memory circuit is the Papez ...
