..., anatomical acuity was estimated to be approximately 3 cycles per degree (cpd) in both sexes. However, a behavioural optomotor assay found significantly lower mean acuity in males (0.8 cpd) than females (3.0 cpd), which was not explained by differences in eye size between males and females. An additional...

... and have at least two spectral classes of photoreceptors (λ max =500 and 519 nm). From the results of optomotor behavioral experiments, we estimate the eyes of A. heterochaelis provide spatial vision with an angular resolution of ∼8 deg. We conclude that snapping shrimp have competent visual systems...

... of pattern contrasts. The optomotor response decreased as a function of decreasing luminance, and the lower limit of the moth's contrast sensitivity was found to be between 1 and 5%. The preferred spatial frequency for M. sexta increased from 0.06 to 0.3 cycles deg −1 as the luminance decreased...

... if the odour source is situated close to it. We implement a model of visuomotor control consisting of three parallel subsystems: an optomotor response stabilising the model fly's yaw orientation; a collision avoidance system to saccade away from looming obstacles; and a speed regulation system. This model...

... reflexes do not vary with the simultaneous presentation of odor ( Fig. 2C , compare i and iii). In addition to an expanding/contracting visual stimulus, we examined the influence of odor on a suite of visual reflexes including stripe fixation, optomotor stabilization and object avoidance. Odor did...

Avoidance of a laterally positioned focus of expansion emerges from an inversion of the optomotor response when motion is restricted...

...F. Claire Rind ABSTRACT Completely unrestrained moths show an optomotor turning response to horizontal movement during pre-flight warm up or flight. As the moth warms up there is a sequential recruitment of first neck, then abdominal, leg and finally some wing muscles, into the optomotor turning...
