Pay Attention: $2.7 Million Grant to Map Brain’s Attention Network

By Becky Oskin

From moment to moment, the brain processes millions of pieces of information. When people need to focus on a critical task, special circuits in the brain’s attention network kick in to filter the information firehose.

A new project with UC Davis neuroscientists and bioengineers from the University of Florida will explore the brain circuits that allow us to focus our attention.

Podcast: Visual Attention and Meaning

In this episode of the Three Minute Egghead podcast, I talk to John Henderson of the UC Davis Center for Mind and Brain about a new paper from his lab that overturns current thinking about visual attention.

It’s usually thought that our eyes are drawn to objects that are salient or “stand out” from the background. But this “magpie theory” of attention is wrong, Henderson says. He and postdoc Taylor Hayes show instead that our eyes are drawn by parts of a scene that have “meaning.”
