Final answer:
Dopamine response increases with the probability of a reward, due to an increase in stimulatory receptors at synapses with experience. In terms of entropy, it increases with disorder in a system and decreases with increased order, in accordance with the second law of thermodynamics.
Step-by-step explanation:
The student's question relates to dopamine (DA) response in relation to reward probability. Based on the provided information and literature on neurobiology, Dopamine (DA) response increases with higher reward probability. This is because there is an increase in the ratio of stimulatory to inhibitory receptors at the synaptic membrane with experience, which suggests a heightened response towards potential rewards.
Regarding entropy, it relates to the amount of disorder within a system. Typically, when a system becomes more disordered, entropy increases. Conversely, if a system becomes more ordered, entropy decreases. The changes in entropy are governed by the second law of thermodynamics, which states that in an isolated system, entropy will tend to increase over time.
