Fig. 6
Adult morphants show normal locomotor and habituation but impaired freezing behaviour.
Locomotor activity was measured as (A) distance travelled in metres in the open field tank, (B) time spent in the centre of the open field tank, (C) time spent in the dark compartment of the place preference tank, and (D) Percent time fish spent freezing in the open field tank. Habituation within these paradigms was assessed by comparing swimming behaviour in the 1st minute with the 10th minute. Shaded areas represent percentage area of tank defined as centre (open field tank) or dark (place preference tank). Freezing behaviour was abolished in both th1-morphants. (repeated measures ANOVA followed by Bonferroni′s test) *p<0.05, **p<0.01, ***p<0.001.
