In the year 2047, the rescue ship "Lewis and Clark" is sent to investigate the mysterious reappearance in the orbit of Neptune of an experimental ship, the "Final Horizon", disappeared years before with all its crew. Once there, the astronauts will lose their sanity ... and we cannot count more to avoid incurring spoilers of the film Event Horizon (Final Horizon).
The brains of astronauts can also be affected if they travel to deep space, but not for the causes of the film, but for others that have been reflected in a recent study published in the magazine eNeuro.
Exposure to chronic low dose radiation (conditions present in deep space) cause neuronal and behavioral deficiencies. At least, it is what is reflected in mice.
Charles Limoli and his colleagues at the University of California Irvine, Stanford University, Colorado State University and the Eastern Virginia School of Medicine exposed the mice to low-dose chronic radiation for six months.
After exposure, radiation impaired cellular signaling in the hippocampus and prefrontal cortex, resulting in learning and memory problems. It also affected the tonsil, porque observed an increase in anxiety behaviors.
If these risks are confirmed in astronauts (ae knows that radiation interrupts signaling among other processes in the brain), it will be imperative to develop safety measures to protect the human brain from radiation during deep space missions while astronauts are They prepare to travel to Mars.
