Fig. 7.

Spontaneous changes of motor and EMG responses to tilts in a premammillary rabbit. Sequential recordings of responses in (A-D) were separated by several minutes. Designations as in Fig. 2 and 5. In (A-D), amplification in EMG channels was the same. Note the gradual decrease of postural corrections (S) and EMG responses, reflecting a spontaneous decrease of excitability of the animal. Also note that body displacements (S) were in anti-phase with tilts in (A,B) and in-phase in (D).
