"Modeling vision based on a linear receptive field poses several inherent problems: it changes with each input, it presupposes a set of basis functions for the visual system, and it conflicts with ...

One theory about why the visual system is arranged hierarchically is that it helps with object recognition. If receptive fields were tiny, the brain would need to integrate more information to ...

Albright, director of the Vision Center Laboratory at of the Salk Institute and an expert on how the visual system works ... characteristics, called receptive fields, have different sizes ...

How that visual 'clutter' affects visual processing ... while visual stimuli were presented in and outside of their receptive fields. During this task, researchers recorded neural activity in ...

To do so, they trained macaque monkeys — a species whose visual systems and abilities are most similar to humans — to fixate on the center of a screen while visual stimuli were presented in and ...
