Researchers find neural activation patterns were predictive of the contents of voluntary visual imagery as far as 11 seconds before the choice of what to imagine. These results suggest that the contents of future visual imagery can be biased by current or prior neural representations.
Study may provide key insights into the visual system and perception.
Visual neurons selectively respond to color and shape along a continuum. While some neurons are only activated by either a specific color or shape, others are responsive to color and shape simultaneously. The findings contradict previous beliefs about how visual processing works.
A new tool is allowing researchers to interactively explore the hierarchical processes that happen in the brain when it is resting or performing tasks.
Researchers report they have identified neurons in the visual cortex that selectively respond to an intermediate color, not just primary colors.
A new study challenges 75 year old dogma of mammalian vision. Researchers have shows the post rhinal cortex obtains visual data from the superior colliculus and is not dependent upon information from primary visual cortex.
