Neuroscientist challenges decades-old model of how vision and thinking work in the brain
By
Grant Currin
Summary
Neuroscientist Nuttida Rungratsameetaweemana is challenging the long-held conventional view that vision is a passive, feed-forward process where raw visual data travels from the eyes through waystations to the cortex for higher-level thinking. Her team's fMRI research reveals unexpected activity in the earliest visual areas of the brain, suggesting that perception and cognition are more deeply intertwined than previously thought. The work is reshaping the understanding of the brain's circuitry and its remarkable efficiency.

· 4 pulledNuttida Rungratsameetaweemana is challenging a story neuroscience has told for decades.
According to the conventional account, our eyes collect raw information and relay it through a series of nerves and waystations that lead deep into the brain, eventually reaching the cortex.
Her group's work is complicating that account.
Last year, the team published fMRI scans showing unexpected levels of activity in the earliest visual areas of
