Space travel expands brain's volume; makes it bigger: Scientists' startling discovery

In a first, researchers revealed in a study published in scientific journal of Riological Society of North America that humans who travelled to space and lived re expanded ir brain volumes, as it apparently got bigger in size. To conduct examination, scientists used MRI brain scans on at least 11 astronauts before y left Intercontinental Area Station, and later, upon return, it was found that images that illustrated before-and-after status of human brain differed exceedingly.

findings were key in answering some important questions about how well-suited humans were for space travel, and long-term effects it can have on human brain. 

le author of study, Larry A. Kramer, MD, from University of Texas Health Science Center at Houston, said, “When you’re in microgravity, fluid such as your venous blood no longer pools toward your lower extremities but redistributes heward, that movement of fluid toward your he may be one of mechanisms causing changes we are observing in eye and intracranial compartment.” Approximately 60% of crew members of International Space Station have reported altered visual acuity after long-duration exposure to microgravity, as per study.

NASA involved in furr research

According to study, as researchers investigated furr, y found that  influence lasted for about a complete year after astronauts returned to Earth. Modifications to flow of cerebrospinal fluid were also pointed out, even though astronauts did not report signs and symptoms of any change in activity, and would look to be healthier. It was, however unclear, what impact alteration in size of brain was felt by astronauts and potential space vacationers after y h returned to earth. 

Furrmore, NASA and or space agencies have been conducting research on ways to mitigate physical consequences of spaceflights on astronauts, according to study. “If we can better understand mechanisms that cause ventricles to enlarge in astronauts, n research could benefit patients with brain-related conditions,” Kramer said.
