  • Title: After-effects of fusimotor stimulation on spindle la afferents' dynamic sensitivity, revealed during slow movements.
    Author: Baumann TK, Emonet-Dénand F, Hulliger M.
    Journal: Brain Res; 1982 Jan 28; 232(2):460-5. PubMed ID: 6231080.
    Abstract:
    After-effects of fusimotor action on dynamic sensitivity of spindle primary afferents from soleus resulted from low rate stimulation of both static and dynamic gamma-axons. Sensitivity to small sinusoidal stretches superimposed on triangles was enhanced during triangular lengthening but not during shortening. These after-effects were elicited by fusimotor stimulation during preceding triangular shortening, but not during lengthening. Given these characteristics, they may be important functionally during alternating rhythmic movements.
