After You Die, Some Cells in Your Brain Become More Active – Futurism

Some, according to a brand-new study, will end up being incredibly active, growing to brand-new sizes for several hours after death.Its morbid to believe about your brain becoming more active after youre gone, but the University of Illinois at Chicago (UIC) scientists behind the discovery stressed in a press release that it does not indicate people are mindful or that the so-called “zombie genes” that activate this neural activity might do anything as significant as reawakening the dead.Instead, the study, which was released Tuesday in the journal Nature Scientific Reports, has major implications for the way neuroscientists study the brain– specifically when those studies rely on human tissue samples.Specifically, the group discovered that glial cells– which arent straight linked to neural activity however supply an assistance system for the brain– activated, swelled up, and even grew new appendages right as the other cells around them passed away off.”That glial cells increase the size of after death isnt too unexpected given that they are inflammatory and their job is to tidy things up after brain injuries like oxygen deprivation or stroke,” research study coauthor Dr. Jeffrey Loeb, head of neurology and rehabilitation at the UIC College of Medicine, said in the press release.That postures a bit of an issue for the field, because much of the research study that researchers have actually done on neurological conditions like brain injuries or Alzheimers Disease is conducted on brain tissue collected after death or surgical treatment, and runs under the assumption that brain cells simply pass away off like any other, Loeb added. “The great news from our findings is that we now know which genes and cell types are stable, which degrade, and which increase over time so that results from postmortem brain research studies can be better understood.
