A theory which accounts for both increase of accuracy and decrease of time taken for sensory-motor performance with practice is proposed within the general concept that signals from sense organs and in the central nervous system have to be detected against a background of random neural activity (“neural noise”).

The degree of impairment of a motor performance test under the influence of alcohol (1.4–2.0 g/kg) was increased progressively by increasing doses of pyrazole (0–3.5 mmol/kg), which had no discernible effect of their own. Blood alcohol concentrations were not affected by pyrazole at the times of testing, indicating that the interaction was at the level of the central nervous system.

The introductory tutorial to this special issue was written for readers with engineering background with the aim to provide the basis for comprehending better the natural motor control and the terminology used in description of impairments and disability caused by to CNS injuries and diseases. The tutorial aims to emphasize the differences between natural and artificial control, complexity of sensory-motor systems in humans, the high level of articulation redundancy, and the fact that all of the said systems are modified after the central nervous system lesion. We hope that the tutorial will simplify the following of the subsequent papers in this special issue dedicated to the use of electrical stimulation with surface electrodes for assisting motor functions.
