It is interesting to note that the drinking threshold of the R< D rat was more than twvice as high as the drinkingtlhresholds of the two D< R rats. It seems likely that its electrode fell close to btut juLst oustide of tissue whose stimulation mediates thirst. Either it was located in tissue whose stimulationnmedi-ates reward, or, in the course of raising the current so that it spread into tissue that medi-ates thirst, it apparently also spread into tissuLe that mediates reward. The electrodes of the D< R rats probably fell in or very close to tissue that mediates thirst, so that, to induce drinking, it was uinnecessary to raise the current to such a high level that it ap-preciably spread into tissuLe that mediates reward. Histological analysis of the rats' brains indicated that all the electrodes used in the experiment fell in the perifornical area of the lateral hypothalamrUs at the level of the anterior part of the ventromedial hypothala-mic ntucleus. The location of the stimuLlating tip of the electrode of rat three did not appear to differ grossly from the location of the electrode tips of the other rats. However, the area of the lateral hypothalamuLs that mediates thirst has not yet been mapped oUt thoroughly enough to enable uis to say whether or not the electrode tip of rat three was in the periphery of thisarea. 3.
