[Functional features of wind-sensitive receptors triggering the wing muscle neurons of the desert locust, Calliptamus barbarus].
At each side of the head of C. barbarus, 5 receptive fields were found triggering  the activity of neurons which directly control the work of wing apparatus. Total number of wind-sensitive receptors (presented by trichoid sensillae) amounts up to 200. Lateral receptive fields 1 and 5 are most developed and contain 24 +/- 5 and 23 +/- 4 sensillae respectively. In the response of a receptor to adequate stimulation, two components may be differentiated--phasic and tonic ones. The discharge frequency of the tonic component is equal to 90--100 impulses per sec. Simultaneous recording of impulse activity in axons of two receptors reveals a possibility of interaction of the receptors. In the experiments performed, this peripheral interaction was of the inhibitory nature. Functional peculiarities of the receptor investigated are discussed.
