Extra forces evoked by other methods and their length-dependent modulation in an adult decerebrate cat. Force produced by stimulating the LGS nerve at 40 Hz for 20 s at muscle lengths of −2.5 mm (A) and +10 mm (B) from neutral. Force produced by stimulating the LGS nerve with a triangular frequency ramp from 4 to 60 Hz and back down to 4 Hz in a 6 s period at muscle lengths of −2.5 mm (C) and +10 mm (D) from neutral. The dotted vertical line represent the point of stimulation at 60 Hz and the curved dotted line represents a smoothed hypothetical symmetric force profile on the descending slope of the frequency ramp. The gray area illustrates the extra force, which is expressed as a percentage of the total force.
