Figure 5.

Individual examples of conditioned eyeblink responses in a control subject (A), a PICA patient (cer-09; B), an SCA patient with involvement of cerebellar nuclei (cer-20; C), and with a pure cortical lesion (cer-18; D). Rectified and filtered (45 Hz) EMG recordings are shown of the affected (top) and unaffected (bottom) sides in patients and the first and second tested sides in the control. Dotted vertical lines indicate onset of the CS (tone) and the US (air puff, 0 ms). Mean values of conditioned eyeblink responses in paired trials are shown. Amplitudes are normalized to the unaffected side (controls, second tested side) set as 100%.
