In the thalamic degree, pain pathways have two significant web-sites of termination: ventrocaudal and medial. The ventrocaudal thalamus receives nociceptive enter directly from projecting spinal neurons. Neurons during the ventrocaudal thalamus venture directly to the somatosensory cortex (Willis, 1985). The medial thalamus gets some indirect enter from your spinal wire, but On top of that, it gets An important enter from your region of your brain stem reticular formation to which the nociceptive spinoreticular neurons project.

The nociceptor is characterised by its reaction to noxious warmth, force, or chemical stimuli. The ''pain'' information is coded inside the pattern and frequency of impulses inside the axons of the principal afferent nociceptors. You will find a direct relation amongst the intensity on the stimulus plus the frequency of nociceptor discharge (Figure 7-three).
