The rise in transmural pressure results in the activation in the click here trigeminal nerve with consequent antidromic stimulation with the sensory nerves that may be translated into the consequent release of pro-inflammatory peptides (compound P and calcitonin gene-similar peptide) at the level of really hard vessels within the meninges [177,178].
These neurons differentiate involving kinds of stimuli and may react otherwise based upon whether it's heat, cold, tension or electrical stimulation.
