An international team from the Champalimaud Centre for the Unknown (CCU), in Portugal, and the University College London (UCL), in the UK, has uncovered a previously unknown effect of serotonin on learning. Their results are published in the June 26 2018 edition of the journal Nature Communications.
Serotonin is one of the main chemicals that nerve cells use to communicate with each other, and its effects on behavior are still unclear. For a long time, neuroscientists have been set on constructing an integrated theory of what serotonin actually does in the normal brain. But it’s been challenging to pin down serotonin’s function, especially for learning. Using a new mathematical model, now the authors found out why.
