title: [Effect of chronic anosmia on morphofunctional parameters of the gustatory system primary centers of the carp Cyprinus carpio].
abstract: Morphofunctional state of neurons in primary centers of olfactory, external and intraoral gustatory systems in carp yearlings was studied at different time after bilateral anosming, with use of methods of morphometrical, biochemical, and histochemical analyses. The olfactory deafferentation produces centripetal translocation of olfactory bulbs and development of their degenerative changes. Chronic elimination of olfactory reception in carps leads to activation of neurons in the facial lobe of medulla--the primary center of the external gustatory system. The neuronal complexes of the vagus lobe representing the primary center of the intraoral taste did not have a similar reaction to elimination of the olfactory reception. The high level of central interaction of the fish olfactory and gustatory systems and its role in providing reliability of alimentary behavior are discussed.
