Interaction of hypertonic NaCl solution and neural stimuli on lateral preoptic neurons.

In this paper, the relationship between the septum and the lateral preoptic area (LPO) were demonstrated through an electrophysiological study where the patterns of responses of LPO neurons were classified. It was shown that septal (S) stimulation could induce modifications of LPO neuron responses to hypertonic NaCl, a dipsogenic stimulus. These findings suggest that the septal stimulation may partly alter thirst through a modification of LPO cell responses.
