Fig. 7. Instantaneous firing rates of the carbohydrate-sensitive taste cells. (A) Response of the carbohydrate-sensitive taste cell in the medial styloconic sensillum to 1 mmol l^–1 inositol, 200 mmol l^–1 glucose and the mixture of both. (B) Response of one carbohydrate-sensitive taste cell in the lateral styloconic sensillum to 1 mmol l^–1 inositol, 200 mmol l^–1 glucose and the mixture of both. (C) Response of the second carbohydrate-sensitive taste cell in the lateral styloconic sensillum to 200 mmol l^–1 sucrose. We show mean ± s.e.m.; N=8–16 taste cells per panel (each from a different caterpillar).
