(Medical Xpress) — Researchers at the Institut Pasteur and the CNRS have recently identified in mice the role played by neo-neurons formed in the adult brain. By using selective stimulation the researchers were able to show that these neo-neurons increase the ability to learn and memorize difficult cognitive tasks. This newly discovered characteristic of neo-neurons to assimilate complex information could open up new avenues in the treatment of some neurodegenerative diseases.
