As the 1a inhibitory interneurone receives both excitatory and inhibitory inputs from the descending pathways, lack of supraspinal control can decrease the level of reciprocal inhibition leading to more co-contraction. This combination of influences is described as reciprocal innervation. Reciprocal ...
