<p>An apparatus (10) for identifying nerve axons (18) comprises a thermal sensor (14) for sensing heat in a nerve axon caused by the passage of a nerve impulse therealong and a monitor (16) for displaying a thermal image. Alternatively an LED arrangement may be used to indicate presence/absence of heat in the nerve axon. A signal processing means (20) is provided for processing the image signal and a stimulation means (22) may be provided for stimulating the passage of a nerve impulse along an axon (18). A timing means may be provided for timing the passage of an output from the thermal imaging device and/or the signal processing means to coincide with the stimulation of an axon (18) thereby to enhance to image quantity. In operation, the thermal sensor (14) is focused on the nerve axons (18) and an operator views monitor (16) in order to identify a nerve axon. <IMAGE></p> |
