Changes in water intake following pharyngolaryngeal deafferentation in the rat.
The role of afferent information arising from the pharyngolaryngeal region in the regulation of water intake was evaluated in rats. The animals received picric application to the mucosa of either the pharyngolaryngeal or the hard palate region. Water intake of the pharyngolaryngeal treated animals was reduced significantly, while no reduction in water intake was shown in the control and hard palate treated animals.
