The terminal branches of motoneurons can be excited by electrical current pulses delivered via needles inserted intramuscularly. Observations are reported which indicate that tungsten semi-microelectrodes suitably positioned in a muscle belly can excite antidromically a large proportion of the alpha-motoneurons of that muscle, at stimulus strengths weak enough to avoid spread of excitation to motor units of adjacent muscles. Some gamma-motoneurons and afferent axons can also be excited by… CONTINUE READING
