Hygroreceptor mechanism in the antenna of the cockroachPeriplaneta


Antennal hygroreceptors of the cockroach,Periplaneta americana L., have been investigated electrophysiologically. Two antagonistic types are present. One responds to moisture, the other to dryness. 1. The moist receptor responds to liquid water with an output pattern almost identical to that evoked by 100% r.h. stimulation (Figs. 2, 3). However, it is not… (More)
