Fig. 4From: Identification of environmental stressors and validation of light preference as a measure of anxiety in larval zebrafishComputation of choice index reveals significantly increased dark avoidance in larval zebrafish exposed to heat, cold and UV stressors. a Choice index for the larval zebrafish after the treatment for heat stress. b Choice index for the larval zebrafish after the treatment for cold stress. c Choice index for the larval zebrafish after the treatment for UV light. Data are presented as scatter plots showing individual sample values and error bars representing mean and 95 % CI. **p < 0.01; student t tests compared to control (unstressed) groupBack to article page
