- adj.describing impulses travelling ‘the wrong way’ in a nerve fibre. This is rare but may happen in shingles, when the irritation caused by the virus in the spinal canal initiates impulses that travel outwards in normally afferent nerves. The area of skin that the sensory nerves supply (usually a strip on the trunk) becomes painfully blistered. Antidromic impulses cannot pass synapses, which work in one direction only.
