Fig. 7 Motor asymmetry in zebrafish.

a For a right-biased larva, the dominant right PT-habenula pathway imposes right motor bias by modulating symmetric visual drive and suppressing the left PT-habenula pathway. b Competition between PT-habenula units is eliminated after unilateral ablations, strengthening motor bias. c Asymmetric visual input after unilateral enucleation overrides PT-habenula modulation of motor output. d Symmetric visual stimuli, after bilateral ablation of PT-habenula units, eliminate motor bias leading to randomized turn direction.
