Ascending Pathways Transmitting Nociceptive Information in Animals

  • William D. WillisJr.


The responses of animals to noxious stimuli are comparable to those of humans and thus include both sensory and motor reactions (37). Furthermore the sensory component of the pain response is divisible into sensory-discriminative and motivational-affective aspects (61). This chapter emphasizes the ascending tracts of the spinal cord that are likely to play an important role in the sensory responses to noxious stimuli in animals, especially in common laboratory animals such as the monkey, cat, and rat.
