Fig. 3. Reversible muscarinic blockade of flight initiation. (Ai,Aii,Aiii)
Responses to wind before, during and after (wash) perfusion with atropine (10
mmol l–1) in the same deafferented preparation. (B) Atropine
(10 mmol l–1) and (C) scopolamine (10 mmol
l–1) both block flight initiation by pilocarpine (5 mmol
l–1). Top traces show condensed, and lower traces expanded
excerpts of electromyograms as in Fig.
