During feelings of anxiety, the brain kicks the heart into overdrive. But as it races, does the heart, in turn, talk to the brain? For centuries, scientists have debated whether the heart holds sway over the mind, and now, research published today (March 1) in Nature suggests that physical states can influence emotional ones. The study found that an elevated heart rate can cause anxious behaviors in mice—but only in risky circumstances. This suggests that interventions that target the heart might be effective treatments for panic disorders, the authors suggest. – Natalia Mesa (March 1, 2023)

We didn’t know that was even controversial. Even a mouse would have to be concerned. What he can do about it is, of course, another matter.

The paper is open access.
