When you die, most of the cells in your brain will be slowly blinking. But some, according to a new study, will become extremely active, growing to new sizes for several hours after death.
It’s distorted to think about becoming your brain More Active after you left, but University of Illinois at Chicago (UIC) researchers in Chicago insisted in a press release that it doesn’t mean people are conscious or the so-called “zombie genes” that trigger this neural activity. Can do anything as dramatic as resurrecting the dead.
Instead, the study, which was published Tuesday in the journal Nature Scientific Reports, Has a major influence on the study of neuroscientists’ brains – especially when those studies rely on human tissue samples.
In particular, the team found that globular cells – which are not directly connected to neural activity but provide a support system for the brain – are activated, swallowed, and new cells grow around them as other cells around them die.
UIC’s Head of Neurology and Rehabilitation, Chairman Dr. “It is not surprising that glomerular cells grow larger after death and that their job is to clean things up after injuries such as brain injuries or stroke strokes,” said Jeffrey Loeb. College of Medicine, said in a press release.
It also poses a bit of a problem for the field, as most of the research done by scientists on neurological conditions such as brain injuries or Alzheimer’s disease is done on brain tissue collected after death or surgery, and works under the assumption that brain cells simply die. Is. Close like anyone else, Loeb added.
“Our findings do not mean that we should abandon human tissue research programs, they simply mean that researchers need to consider these genetic and cellular changes, and reduce postmortem intervals as little as possible to reduce the severity of these.” Changes, ”Loeb said in the release. “One of the good news from our findings is that we now know which genes and cell types are stable, which degenerate, and which increase over time so that the results of postmortem brain studies can be better understood.”
