Transport mechanisms for serotonin

Researchers at The Forsyth Institute have discovered that the transport mechanisms for serotonin - the chemical substance involved in transmitting signals between neurons, and which has a role in anxiety and mood disorders - play a key role in determining where organs are positioned in the body during embryonic development.
