Gustatory receptor neurons (GRN) responses of Bombyx mori styloconic sensilla to individual compounds and binary mixtures. a Representative traces, with spike shape superimposition, from lateral styloconic sensillum during the first second of stimulation with sugars. b Magnification of the above traces showing the types of spikes during the first 300 ms (box in a). c Representative traces, with spike shape superimposition, from medial styloconic sensillum during the first second of stimulation with bitter compounds. d Magnification of the above traces showing the types of spikes during the first 300 ms (box in c). Distinct spike types are indicated by empty and filled circles, crosses and filled triangles. Double labelling indicates the simultaneous occurrence of two spikes. The concentration of KCl was 50 mM and the concentrations of all other compounds were 10 mM. Mixtures consisted of 10 mM of each component
