The production of dendritic varicosities (DVs) involves microtubules, and does not alter passive membrane properties of neurokinin-1 receptor (NK-1R) expressing neurons in the RVM. (A) Pretreatment with the microtubule stabilizer taxol (10 μM) prevents the formation of DVs by 30 sec exposure to 1 μM substance P. Data are the mean ± S.E.M of determinations in 3–4 slices. (B) Current-voltage relationship for three NK-1R expressing RVM neurons before (circles) and 15 min after a 30 sec exposure to 1 μM Sub P (squares). (C) Brief exposure to Sub P did not alter passive membrane properties of NK-1R-expressing RVM neurons. Data are mean ± S.E.M. for three neurons.
