Priority coding in the visual system
Although we are continuously bombarded with visual input, only a fraction of incoming visual
events is perceived, remembered or acted on. The neural underpinnings of various forms of …

Locomotion enhances neural encoding of visual stimuli in mouse V1
MC Dadarlat, MP Stryker - Journal of Neuroscience, 2017 - Soc Neuroscience
Neurons in mouse primary visual cortex (V1) are selective for particular properties of visual
stimuli. Locomotion causes a change in cortical state that leaves their selectivity unchanged …
