what we saw was that the neurons don't wait until the blood is is rehydrated um they also don't do what the arrp neurons do is meaning they don't look at the water and predict how much water they're going to drink but instead they get a signal from the mouth which every time the mouse takes a lick of water their activity goes down a little bit and basically they track in that way the volume of water that's passed through the mouth um they also get the signal from the blood relaying the osmolarity of the blood and they compare these two and basically when the mouse is drank enough in order for the animal to predict that the blood osmolality is going to return to normal then the animal stops drinking
