The study investigated the relationship between cerebral lateralisation and inhibitory control in zebrafish. Lateralisation was assessed using a mirror test. Fish were observed in an apparatus with mirror walls and eye preference for observing the mirror image was recorded. This preference was used to calculate the relative and the absolute lateralisation index. Inhibitory control was assessed using a foraging task. Fish were exposed to live prey enclosed inside a transparent tube. The number of attacks and its reduction over time were used as measures of inhibition.
