The Effects of Microgravity on the Ventricular Size of the Brain

The same way you can cuss your the brain becomes concussed. There was significant increase in the lateral ventricles for the first six months of being in microgravity and then a kind of plateaued. Was their intracranial pressure the same? That's a good question. So they specifically studying changes to the ventricular size in astronauts based upon their length of stay, their prior history of missions, and like, so how many prior missions have they had and what time did they have to recover?
