Socially induced changes in serotonin neurones in desert locusts

What is it about?

Serotonin is a common neurochemical with extensive roles in orchestrating behavioural plasticity, particularly in a social context. A dramatic example is the rapid transformation of desert locusts from cryptic and asocial animals into swarming crop pests, which is triggered by a surge in serotonin within their nervous system when locusts are first forced into a crowd. We have identified the serotonin-producing neurons responsible for this plasticity-inducing surge. Prolonged group living causes
