摘要: This report, the second of three, describes treadmill galloping by cats that were trained solely food reward. Four young adult animals provided data at various velocities from 2.3 to 4.1 m/sec. Another cat galloped 2.0 The overall speed range was lower than in first study, probably because not punished for failure run and, also, they slightly smaller and younger cats. At any one velocity, several successive strides available whose footfall pattern steady state, or invariant. same three patterns seen had been found previously an aversive test situation: rotatory galloping, transverse half bound. gallop most frequently used. In general, findings movements a single limb, also interlimb timings (with some exceptions during slow galloping), similar those as such measures stride length percentage zero support. For substantial number runs increments between 3.1 m/sec, it possible show linear trend duration function although total change only approximately 30 msec. low-speed special interest, its showed continuum coordination could occur trotting this type gallop. It concluded similarities food-reinforced under control far outweighed differences, imply economy their neural control.
