Effect of laminarin injection on chemosensory and motor function. A. Examples of extracellular recording of afferents in the superior lip nerve before and after application of n-amyl acetate (4 ppm) of animals injected one hour prior with vehicle only (top trace) or laminarin (bottom trace). B. Average action potential frequency (bin size 30 sec) of afferents in superior lip nerve 3 minutes before and 2 minutes during amyl acetate application. There is no difference in response upon n-amyl acetate application between the two different treatment groups C. Average change in the number of rasps evoked by application of pond water (DS) or sucrose (0.4%). Only sucrose induced a robust but similar response in animals injected with vehicle or laminarin.
