UV-laser ablation of sensory cells in living insects

UV-laser ablation of sensory cells in living insects ). The handling of living insects, the survival, and physiological response after treatment are described. We selectively interrupted the d-receptor of the tympanal organ, which is the receptor system responsible for the locust’s sensitivity in the high-frequency range (>10 kHz). The effects of the laser treatment were tested by determining hearing thresholds in electrophysiological recordings from the tympanal nerves. In agreement with the literature, the interruption of the d-receptors led to a significant shift towards higher values of the thresholds in the high-frequency range. Future perspectives and biological applications of UV-laser ablation are discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Physics A: Materials Science Processing Springer Journals

Abstract

). The handling of living insects, the survival, and physiological response after treatment are described. We selectively interrupted the d-receptor of the tympanal organ, which is the receptor system responsible for the locust’s sensitivity in the high-frequency range (>10 kHz). The effects of the laser treatment were tested by determining hearing thresholds in electrophysiological recordings from the tympanal nerves. In agreement with the literature, the interruption of the d-receptors led to a significant shift towards higher values of the thresholds in the high-frequency range. Future perspectives and biological applications of UV-laser ablation are discussed.
