  • Study Advances New Theory of How the Brain Is Wired
    For decades, scientists thought they had a pretty clear understanding of how signals move through the cerebral cortex.  Now a study by Columbia neuroscientist Dr. Randy Bruno indicates this longstanding view is incorrect. Looking at how sensory information is processed in rats, Bruno found that signals are processed in two parts of the cortex simultaneously rather than in series—almost as if ...

  • How visual attention affects the brain
    New research shows for the first time how visual attention affects activity in specific brain cells. The study shows that attention increases the efficiency of signaling into the brain's cerebral cortex and boosts the ratio of signal over noise.

  • Problem-solving governs how we process sensory stimuli
    Various areas of the brain process our sensory experiences. How the areas of the cerebral cortex communicate with each other and process sensory information has long puzzled neuroscientists. Exploring the sense of touch in mice, brain researchers now demonstrate that the transmission of sensory information from one cortical area to connected areas depends on the specific task to solve and the ...
