Recently discovered ‘single-pixel vision’ in fish could help researchers understand how humans are able to spot tiny details in their environment—like stars in the sky.
In a paper published this week, researchers at the University of Sussex found that zebrafish are able to use a single photoreceptor to spot their tiny prey.
This photoreceptor is like an ‘eye pixel’ and seems to provide enough of a signal for the fish to go and investigate the stimulus.
