The method of electrophysiological unit recording was used to study the interaction of neurons among the following nuclear masses: (1) the nucleus semilunaris accessorius thalami (nSA), which relays gustatory and splanchnic afferents in the thalamus, (2) the nucleus supraopticus hypothalami (nSoH) and the nucleus paraventricularis hypothalami (nPv) which are known to control water retention, and (3) the area lateralis hypothalami (ALH) and the nucleus entopeduncularis (nEp) which are implicated in the control of water intake. Neuronal activity of these nuclei was altered by intracarotid infusions of a 3% NaCl solution or distilled water, or by electrical pulses applied via a concentric stimulating electrode to the nSA or to neurons of the ALH-Ep or the nSoH. It was found (Fig.9) that neurons of the nSoH and nPv function as osmoreceptors (Fig. 9.1, 9.2) whereas those of the ALH-Ep do not. The activity of the latter depends on the interaction of tonic excitatory and inhibitory influences (Fig. 9.3, 9.4) which are relayed to the ALH-Ep neurons via the nSA. Therefore, oropharyngeal stimulation during water intake will gradually alter the activity of the ALH-Ep neurons. This function can serve as a metering device of water consumption. A reverberatory negative feedback circuit (Fig. 9.5, 9.6) provides for interaction between the two hypothalamic control systems suggesting the explanation for many interesting phenomena observed with the regulation of water balance.
