Researchers at the Beckman Institute for Advanced Science and Technology found that early exposure to an environmental chemical called polychlorinated biphenyls, or PCBs, made it more difficult for mice to recover from sound-related trauma sustained later in life.

A team of University of Illinois neuroscientists led by Baher Ibrahim and Daniel Llano recently published a study in eLife that furthers our understanding of how the brain perceives everyday sensory inputs.
