The largest taste hair type of the 20 distal antennal segments is investigated electrophysiologically. Two chemoreceptors respond to potassium chloride, tripotassium citrate but not to choline salts, another one to sucrose, but not to D-glucose and only slightly to D-fructose. No response was obtained with pure water. Spikes with a leading negative phase indicate that the primary process controls an apical spike generator localized in the membranes of the outer dendritic segment. The succeeding basal spike consists of two positive phases, that are interpreted as the result of two further spike generation zones, one at the dendritic inner segments and the other at the origin of the axon. Spike activity in the mechanoreceptor also starts with negative going spikes, that are followed by a series of solely positively going ones. TTX applied to the hair tip inhibits the apical spike generator of the chemo- and mechanoreceptor cells.
