[Reactions of neurons in the dental projection area of the rabbit sensomotor cortex to photic, acoustic and painful stimulation of the dental pulp].
In experiments on unrestrained rabbits interactions of sound (tone, click), light and pain excitation occurring during stimulation of the dental pulp in the neurons of the cortical sensomotor zone, in the area of representation of the dental afferents were studied by the microelectrode method. It was shown that bi- and polysensor convergence of excitation is realized in the cells of this area. It is suggested that convergence of excitation underlies the mechanisms of formation of the integral systemic pain reaction during stimulation of the dental receptors.
