James olds and peter milner (1954) were trying to implant an electrode in a rat's reticular formation when they mistakenly place
d the electrode incorrectly. curiously, as if seeking more stimulation, the rat kept returning to the location where it had been when it received a stimulus from this misplaced electrode. on discovering that they had actually placed the device in a region of the _____, olds and milner realized they had stumbled upon a _____.
The answer is <span>hypothalamus; reward center When mammals do actions that make them obtain something desirable, the hypothalamus part of the mammals brain will release dopamine that make us feel calm, happy, and satisfied. This will make us more likely to repeat that actions in order to seek this dopamine reward. </span>
<span>The answer is hypothalamus and for second is a brain center that provides pleasurable rewards, "reward centers".
Reward centers are center in brains which release chemical in body to reward the body for its good actions . Like dopamine is released in human body when we eat food,have sex etc.These chemicals make us repeat these actions for our survival. When rats in the experiment were allowed to stimulate themselves through pedal they would do it to the level of exhaustion.</span>
