Aspects of Sensory Processing through Convergent Neurons

The spinal mechanisms of nociception are generally interpreted in terms of a single-channel transmission system, the gain of which can be modulated by inhibitory processes from both spinal and supraspinal origins. This interpretation is based on the intuitive supposition that neurons putatively involved in a sensory-discriminative nociceptive system might exhibit, in nonpatho-logical conditions, their highest frequencies of firing when noxious stimuli are applied to their receptive fields.
