שאלה | A tone (CS) is presented to an animal, followed by a shock to its feet (US) in a cage with transparent walls. After several trials, the animal will freeze (CR) when the CS is presented, even before the US is given. Then the animal is placed in a cage with smooth black walls and presented with the CS without a shock (US). After several trials, the animal will not freeze if the CS is presented in the black cage. An experimenter records the activity of neurons in the amygdala in the cage with black walls and in a cage with white walls. How will the neurons react in each cage?

		The neurons will fire more to the CS in the white cage compared to the black cage
		The neurons will fire at the same rate in both cages as long as the CS is presented
		The neurons will fire at a higher rate when the animal is in the black cage on condition that the CS is NOT presented.
		The neurons will fire more to the CS in the black cage compared to the white cage
