Abstract

Neural adaptation, a change in the response of a neuron to repetitive stimulation, is a widespread property of neurons in many networks, including those controlling local reflex limb movements. The majority of previous studies have investigated the steady state properties of neurons rather than considering those of their adapting (transient) response. Bandlimited Gaussian White Noise, sinusoidal and walking stimulation signals have therefore, for the first time, been used to investigate neural adaptation in flexor and extensor motor neurons in the locusts local hind limb control system. Our results show that the adaptation rate of the response of two extensor and one flexor motor neuron are the same. We also show that the adaptation rate of the Fast Extensor Tibia motor neuron is affected by the properties of the stimulation signal.
