Summing responses of cat soleus muscle spindles to combined static and dynamic fusimotor stimulation(1).
This is a study of the summation of responses of primary endings of muscle spindles to combined static and dynamic fusimotor stimulation in the soleus muscle of the anaesthetised cat. Summation, expressed as a summation coefficient, K, was measured under a variety of conditions including (1) at several, fixed muscle lengths using steady rates of stimulation, (2) using ramp-shaped increases in s...
متن کاملChanneling of responses elicited by hypothalamic stimulation.
SCIENTIFIC discovery, like mining, often progresses on a discontinuous course. Progress in one direction continues until a point of diminishing returns is reached. A new strike may produce a scurry of activity in another direction. The development of different techniques may prompt the reopening of a closed shaft. Only after a period of such exploration may a more complete picture of the field ...
متن کاملA muscle spindle model and study the effects of static and dynamic γ stimulations on primary and secondary ending outputs
A linear lumped-parameter mechanical model of the muscle spindle is presented. It is shown that the model simulation exhibits the spindle behavior in most aspects of transient ramp-stretch performance. The requirements that such a model places on the mechanisms of fusimotor control are discussed. Then the efficacy of static γ and dynamic γ stimulation on primary ending output and secondary endi...
متن کاملEffects upon spindle discharges of electrical stimulation of static fusimotor fibers with concomitant application of muscle vibration.
Discharges of single afferent fibers from the primary endings of the soleus muscle spindles were recorded from thin dorsal root filaments in cats anesthetized with urethane and chloralose. The distal cut end of the ventral root was split into fine filaments to obtain functionally single fusimotor fibers. The fusimotor fibers obtained in this study were of the static type. The soleus muscle was ...
متن کاملNeural responses elicited by electrical stimulation of the retina.
PURPOSE To study electrically elicited responses (EERs) that are produced by epiretinal stimulation of normal and degenerated retina. METHODS Three biological models of retinal degeneration are compared: normal and rd1 mouse, normal and RCD1 dog, and human with retinitis pigmentosa. In mouse, epiretinal stimulation was accomplished by means of a wire inserted in the vitreous cavity, and singl...
