abstract：:Rats were systemically pre-treated with capsaicin either on the first day of life or at an age of 1 month. Both treatments were found to deplete substance P levels in the trigeminal nucleus caudalis (55.6% and 57.9% depletions, respectively). Extracellular single neurone recordings in the trigeminal nucleus caudalis r...
