TRPA1 and migraine disorder: We report that (i) acute and chronic migraine-like pain induced by systemic NTG in either the light (sleep period) or dark (active period) phase does not affect sleep quantity, depth or architecture of female mice; that (ii) acute migraine-like pain induced by dural IM either in the light or dark phase does not affect total sleep time of male and female mice; and that (iii) acute migraine-like pain induced by UMB, a TRPA1 agonist, in a priming model in the light phase did not affect total sleep time in male or female mice.
