SINs and SOMs: Neural microcircuits for size tuning in the zebrafish and mouse visual pathway.
In many animals, a fast and reliable circuit for discriminating between predator-sized objects and edible (prey-sized) objects is necessary for survival.How are receptive fields in visual brain areas organized to extract information about size? Recent studies from the zebrafish optic read more tectum and the mouse visual cortex suggest de novo shap
