There is no defined limit on the capacity of the brain. The brain's capacity cannot be measured as it is not subject to a defined "space" where the memory is kept, and it is not such that each neuron is responsible for a single memory. The brain has complex mechanisms of memory storage, that even improve if trained.
Brain death: is the legal definition of death. It is the complete and irreversible stop of all brain functions. This means that as a result of severe aggression or severe brain injury, the blood that comes from the body and supplies the brain is blocked and the brain dies.
Agonal phase: occurs with the realization of the preceding events when life is about to break free of the protoplasm, because the protoplasm cannot sustain it for long.
Clinical death: is defined by the cessation of electrical activity in the brain, resulting in irreversible and total loss of neurological activity in the brain and brainstem. When doctors officially declare a person's clinical death, it means there is no cure or return to recovery.
Mortality: It is the condition of being mortal, therefore, of being susceptible to death. However, the term mortality is in most cases related to the statistical studies applied on populations. So mortality appears as a number that seeks to establish the number of deaths over a given population.
