Figure 8

Decreased excitability of the motor cortex contralaterally to the ablation of the left hemicerebellum in a rat, as revealed by the study of recruitment curves of corticomotor responses in the gastrocnemius muscle. Recordings in the gastrocnemius muscle following incremental electrical stimulation of the motor cortex. Plots correspond to the amplitude of motor evoked potentials as a function of stimulus intensity. Filled triangles: stimulation of left motor cortex, open triangles: stimulation of right motor cortex. Fitting with a sigmoidal curve (3 parameters). 95% prediction band and 95% confidence band are illustrated. Amplitudes of recorded motor evoked potentials (MEPs) are expressed in mV.
