Sperm are smarter than previously thought

Sperm are smarter than previously thoughtSperm are smarter than previously thought Human sperm, it turns out, have the beginnings of memory. Anyway, how did you manage to install Peter Brugger (Peter Brugger, a neuroscientist, medical center of the University of Zurich (Zurich University Hospital), once the sperm is turned in one direction, then the next time they possibly rotated in the opposite direction. This behavior is called spontaneous alternation, and it is observed in many living beings. To check whether this cell human sperm, Brugger was observed behavior 714 healthy sperm in the T-shaped channel. As expected, one half of these sperm turned left, the other right. However, in the labyrinth, where the T-shaped fork was preceded by a turn to the right, 58% of the sperm in the end turned left. According to Brugger, if and so tiny channel was even smaller, to the left would turn much more sperm. Just some of them on the road manages to "forget" where to turn. This "remembering" there are two possible explanations. The first is that each turn causes symmetry breaking mechanism, which controls the flagellum of the sperm. This violation is compensated for by rotation in the other direction at the first opportunity. However, there is an assumption that the sperm are able to somehow communicate with each other. "It seems they are roaming in packs," said Brugger. Source:Рњembrana and Madlena.Ru.
