Electrophysiological recordings of taste sensilla. (A) Schematic of single-sensillum electrophysiological recording. An electrode containing a tastant solution is placed over the tip of a sensillum. The tastant enters the sensillum via a pore at the tip of the sensillum and activates taste neurons within. (B) Physiological recordings from Aedes albopictus labellar sensilla in response to sucrose (Top), berberine chloride (Middle; bitter compound), or control diluent tricholine citrate (Bottom).
