Difficult Decisions Involving Perception Increase Activity in Brain’s Insular Cortex, Study Finds

ATLANTA—As the difficulty of making a decision based on sensory evidence increases, activity in the brain’s insular cortex also increases, according to researchers at Georgia State University.

The findings, reported in the journal Neuroscience, shed light on how the insular cortex is involved in processing sensory information to perceive the environment and… more »

Socially Meaningful Sounds Can Change Ear, Improve Hearing, Georgia State Research Study Finds

ATLANTA—Hearing socially meaningful sounds can change the ear and enable it to better detect those sounds, according to researchers at Georgia State University who studied the phenomenon in green treefrogs.

The findings are published in the Journal of Experimental Biology.

“The ear is modifiable,” said Walter Wilczynski, a professor in the Neuroscience… more »
