It is a part of nature and common knowledge that when we die, all of the systems of the body are cut off from both air and blood circulation, resulting in all biological processes ceasing to function.
However, scientists have recently discovered that some brain cells, for a reason they are not privy to as of yet, actually increase activity postmortem.
A team of scientists observed what could only be termed as zombie-like cells that sprouted new tentacles, resulting in the processing of biological activity several hours after death.
A study published by the team in the Scientific Reports journal documented hours of observing the zombie-like cells sprouting new tentacles, establishing new biological processed several hours after death.

The study, titled “Selective time-dependent changes in the activity and cell-specific gene expression in human postmortem brain,” set out to explain the increased activity in the brain of the host after death, where the zombie cells appeared to ramp up, rather than slow down, and continue many critical tasks.
Up until now, most studies were run with the assumption that when both the brain and the heart stop, all remaining biological processes cease as well. The team’s most recent findings will prove to be crucial in future research interpretation on tissues of the human brain.
Most of the current medical information on such disorders of the brain, such as Alzheimer’s, autism, and schizophrenia, is derived from various previous tests and experiments performed on those brain samples acquired postmortem.
The team commented that those researchers in the future will need to consider the currently observed changes, both cellular and genetic, to reduce any possible postmortem changes to acquire a more accurate study.
