“A potentiation of the papaverine‐evoked ICP increase was also observed following pretreatment with bilateral hippocampal application of equimolar doses (250 pmol) of either prazosin (α1‐, α2B‐, α2C‐antagonist), naftopidil (α1A/D‐antagonist), yohimbine (α2‐antagonst), or rauwolscine (α2B‐, α2C‐antagonist).”
