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.
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]
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.
Besides memory, the amygdala also seems to be an important brain region involved in attentional and emotional processes. First, to define attention in cognitive terms, attention is the ability to focus on some stimuli while ignoring others. Thus, the amygdala seems to be an important structure in this ability.

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 ...
Body memory (BM) is a hypothesis that the body itself is capable of storing memories, as opposed to only the brain. While experiments have demonstrated the possibility of cellular memory [ 1 ] there are currently no known means by which tissues other than the brain would be capable of storing memories.
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]
