Dopamine neurons in the dorsal raphe nucleus, when stimulated, cause animals to move away from the area and exhibit aversion, unlike VTA dopamine neurons.

“these vental tegmental area dopamine midbrain dops like 90% of the time when you you hear people talk about dopam NS they mean these ones and they're the ones where you press the lever stimulate the ner will press the lever thousands of times you know and they love to be stimulated yes if if you're a human and you do cocaine you you most people love cocaine they they want they're very pro-social when they're on cocaine and so that's what dopamine neurons were thought to be doing but these other dopamine neurons in the dorsal rap that I will also say is in the brain stem near to an aqueduct where you could detect signals from the body um but these other dopamine neurons in the raap they when you stimulate them animals don't like it they will not work for reward they actually will move away from a space that's where they're being stimulated you know condition place and real-time Place aversion I don't like the feeling of these neurons being activated please stop it”
