Space Radiation May Alter Astronauts' Neurons

sciencehabit writes: NASA hopes to send the first round-trip, manned spaceflight to Mars by the 2030s. If the mission succeeds, astronauts could spend several years potentially being bombarded with cosmic rays—high-energy particles launched across space by supernovae and other galactic explosions. Now, a study in mice suggests these particles could alter the shape of neurons, impairing astronauts' memories and other cognitive abilities. In the prefrontal cortex, a brain region associated with executive function, a range of high-level cognitive tasks such as reasoning, short-term memory, and problem-solving, neurons had 30% to 40% fewer branches, called dendrites, which receive electrical input from other cells.
