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.
Fornix transection studies in macaques [1] have shown that the monkeys were strongly impaired on object-in-scene learning, which is a type of recall memory, specifically episodic-like memory (integrating what and where, although not when). Fornix transection in rodents impairs performance on tasks that require the encoding and retrieval of ...

The definition of legal death, and its formal documentation in a death certificate, vary according to the jurisdiction. The certification applies to somatic death, corresponding to death of the person, which has varying definitions but most commonly describes a lack of vital signs and brain function. [9]
Thanatology is the scientific study of death and the losses brought about as a result. It investigates the mechanisms and forensic aspects of death, such as bodily changes that accompany death and the postmortem period, as well as wider psychological and social aspects related to death. It is primarily an interdisciplinary study offered as a ...
These rituals included mummifying the body, casting magic spells, and burials with specific grave goods thought to be needed in the afterlife. [2] [3] Angelica vestis, in English and European antiquity, was a monastic garment that laymen wore a little before their death, that they might have the benefit of the prayers of the monks.
When anatomists refer to the right and left of the body, it is in reference to the right and left of the subject, not the right and left of the observer. When observing a body in the anatomical position, the left of the body is on the observer's right, and vice versa. These standardized terms avoid confusion. Examples of terms include: [2]: 4
