Schultz’s experiments on phasic firing of dopamine neurons revealed that if there is a delay between viewing the CS and receiving the US, the dopamine neurons 2 A N S W E R S

		After the animal receives the US, the firing rate of DA neurons increases in proportion to the CS-US interval duration.
		After the animal sees the CS, the firing rate of DA neurons increases in proportion to the duration of the CS-US interval.
		After the animal sees the CS, the firing rate of DA neurons decreases in proportion to the duration of the CS-US interval.
		The firing rate after both the CS and US decreases in proportion to the duration of the delay.
