Summary: Stamatakis & Stuber (2012)

Negative reward-related information is carried to the ventral portion of the middle brain (including the rostromedial tegmental nucleus) via projections of the lateral habenula. Stamatakis & Stuber (2012) studied the behavioural complications of selective activation of this particular pathway in the brain in mice. They found that aversive stimuli increased the excitatory drive of the lateral habenula, which resulted in conditioned, passive and active behavioural avoidance of the aversive stimulus. The activity of these projections to the midbrain is thus aversive, and functions to negatively reinforce behavioural response.
