Perceptual learning: is V1 up to the task?
Our ability to make fine visual discriminations improves with practice, and so at some level so must our visual system. A new paper reports that the receptive field structure of a neuron can be fine-tuned for different visual tasks. These findings raise important questions about the circuitry and mechanisms that underly perceptual learning.
