Fig. 8. In general, experimental fish displayed C-starts that were more restricted in their extent than those elicited preoperatively or by sham-operated control animals. Each regression line represents 2 ms as described in Fig. 2. Three consecutive startle responses preoperatively (A1-3) of fish 152 are compared with three responses (B1-3) elicited between 95 and 109 days postoperatively. The most obvious difference is the angle achieved 70 ms after the delivery of the stimulus. The mean angle of the trials in A is 134.1° while that in B is 53.8°.
