Adaptation and fatigue of a mechanosensory neuron in wild-type Drosophila and in memory mutants.

Abstract excerpt

The mechanosensory neuron that innervates the anteronotopleural bristle of Drosophila melanogaster responds with a burst of action potentials to deflection of the bristle towards the body wall. The decay of the firing rate upon sustained deflection is typical of a slowly adapting mechanosensory neuron. Upon repeated monotonous stimulation, the response decreases and the kinetics of adaptation change; the response...
