The difference between an expert’s brain and a novice’s

When learning a new task, brain activities alter over time as mice transition to an expert from a novice. The changes are reflected in neural networks and neural activity. As the animal's knowledge grows, neural networks become more focused. Read More

Deciphering how the brain encodes color and shape

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. Read More

New study reshapes understanding of how the brain recovers from injury

Retinal ganglion cell survival following a stroke depends on whether the pathway to the primary visual area remains active. Cells connected to inactive areas of the visual cortex suffer atrophy and degenerate, leading to permanent visual impairment. Read More

Our Brains Reveal Our Choices Before We’re Even Aware of Them

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. Read More
