How the brain decides whether to hold 'em or fold 'em

A Johns Hopkins study found that the brain's push-pull dynamic between hemispheres contributes to risk-taking behavior, with cumulative feelings from past bets influencing decisions. Researchers used stereoelectroencephalography to analyze neural signals and developed a mathematical equation to calculate each patient's bias.

Can you hear me now?

Researchers at Johns Hopkins University found that the Lombard effect, a phenomenon where animals raise their voices to be heard over noise, occurs in just 30 milliseconds, making it a fundamental temporal reflex. This discovery sheds light on human speech control and reveals a shared auditory process among species.
