Metabotropic group II glutamate receptors in the basolateral amygdala mediate cue-triggered increases in incentive motivation.

Rationale: Reward-associated cues can trigger incentive motivation for reward and invigorate reward-seeking behaviour via Pavlovian-to-instrumental transfer (PIT). Glutamate signaling within the basolateral amygdala (BLA) modulates cue-triggered increases in incentive motivation. However, the role of BLA metabotropic group II glutamate (mGlu) receptors is largely unknown.
