noxious heating of the chloralose-anesthetized cat foot skin to 44-60 degrees c caused a 2-4 fold increase in the amplitude of the primary cortical responses evoked by direct stimulation of the spinocervical tract neurons which receive messages from the heated skin area , but had no influence on the primary responses elicited by stimulation of these neuron axons in the dorsolateral funiculus and even suppressed the primary responses to stimulation of the nerve innervating the heated area .
