The eggs of sea rabbits are a long rope.
Spring is the breeding season of sea rabbits, and hermaphroditic sea rabbits undergo allogeneic fertilization. Oviposition is carried out in the process of mating or several hours after separation, and the produced eggs, which are mutually secreted by protein glands, stick into a slender rope-like strip.
Researchers at the University of California, Los Angeles 14 published a research report in the online journal eNeuro of the American Society for Neuroscience, saying that they used RNA to successfully transfer the memory of one sea rabbit to another.
However, its cell and molecular operation process is very similar to that of human neurons, so it is considered as an excellent model for studying human brain and memory. In this study, the researchers enhanced the defensive contraction reflex of sea rabbits by slightly shocking them.
A contractile response used to protect oneself from potential harm. After electric shock training, the sea rabbit will contract for a long time after being touched, lasting as long as 50 seconds, while the normal sea rabbit's contraction reaction lasts only 1 second.
Subsequently, the researchers extracted RNA from the nervous system of trained sea rabbits and normal sea rabbits, and injected them into sea rabbits that had not received any electric shock. They found that sea rabbits injected with RNA from trained sea rabbits were touched.
It will show a defensive contraction response of up to 40 seconds, but those sea rabbits injected with RNA without electric shock have no such performance. This shows that.
Through RNA injection, the electric shock memory of the trained sea rabbit was transferred to a new receptor. The researchers pointed out that their research is of great value for developing new therapies to restore human memory.
