Functional characteristics of the interneurons of wind-sensitive hair-receptors on the head in Locusta migratoria L.—I. Interneurons with excitatory responses

Neural correlates to flight‐related density‐dependent phase characteristics in locusts

“…Camhi (1969) had demonstrated that the sensory cells innervating each locust wind-receptor hair respond to a persistent wind stimulus with a slowly adapting train of impulses. The sensory cells are excited when the sensillae are inclined, and the frequency of their slowly and incompletely adapting responses is proportional to loss of incline by the hair (Varanka and Svidersky, 1974). The rate of adaptation reported by Camhi (a decrease of 37.5% from the initial rate within 250 m, followed by a plateau) was quite similar to the adaptation exhibited by the TCG responses of crowded locusts in our study.…”

Control of the horizontal flight‐course by air‐current sense organs in Locusta migratoria

“…If this were the case, they would presumably act directly on the flight motor, and the cervical hair plates, which control the head movements, could not take part in course stabilizing torque reaction as they do in the optical stabilization of rolling (Goodman, 1965). The tonic component of the torque reaction, which continued for a t least 10 s, may be mediated by slowadapting (up t o 1 min) interneurones (Varanka & Svidersky, 1974).…”
