Most scientists accept that it involves activation and sensitization of the trigeminovascular system, which includes the sensory peripheral projections to the pain-producing dura mater, and a central projection to the trigeminal nucleus caudalis and its cervical extension, the trigeminocervical complex (TCC). (medscape.com)
In animal models, it has been demonstrated that the central afferent projection to the trigeminal nucleus, using stimulation of the dura mater, also extends to the C2 and C3 regions of the cervical spinal cord, [ 9-13 ] which have been collectively described as the trigeminocervical complex (TCC). (medscape.com)
[ 14 , 15 ] It is thought that the anatomical transition from the trigeminal nucleus to the cervical spinal cord represents a functional continuum and it is likely that inputs to the TCC can explain the common distribution of pain in migraine in frontal, temporal, parietal, occipital and higher cervical regions. (medscape.com)
