How motivation triggers speedy decisions

The rats almost always moved toward the reward location following white noise or a clicking sound but rarely did so when neither of these sounds was broadcast. [...]their reaction times were faster when the sound indicated a large reward (white noise) compared with a small reward (clicking). Neural recordings during the task revealed that BF neurons responded more strongly to sounds that signaled a large reward compared with sounds signaling a small reward, confirming that the activity of these neurons is affected by motivational salience. [...]the activity of BF neurons predicted rats' decision-making speed.
