The nervous system can transmit information across multiple generations - life short science news

Researchers have found that brain cells of nematodes (worms) communicate with germ cells through the release of small pieces of RNA. In this way, the information stored in the brain can be transmitted to the offspring and their descendants.

This stunning observation was made in nematodes in which the small RNAs could not be produced anymore. These animals showed limited capacity to find food. Reintroduction of the small RNA in the nervous system of the worms not only restored the proper food seeking behavior in these nematodes, but also in that of their offspring that could not synthesize the small RNA themselves.

It is currently not known whether the nervous system transmits information across generations in humans.
