A brain chemical that battles despair
...In the new experiments, they sought to explore the role
of ∆FosB in regulating adaptation to stress. Their approach involved first exposing mice to random shocks from which the animals could not escape. Such repeated exposure to inescapable stress tends to increase the lag time for mice to escape su...
