[Mechanism of the protopathic nature of visceral pains].
Experiments on decerebrated cats and rabbits have shown that local nociceptive stimulation (mechanical pressure and burns) of internal organs causes no reflex responses of the motor system. It is suggested that internal organs are either absolutely devoid of or lack specific nociceptors. Insufficiency of inhibitory mechanisms may account for protopathic nature of visceral pain.
