The brain’s state of arousal is the key to many stress- and anxiety-related disorders. Researchers at ETH Zurich have now found a way to influence it with a new biofeedback method.
In brief
Researchers at ETH Zurich demonstrate that the arousal centres in the brainstem can be influenced when we receive feedback about pupil size.
This biofeedback helps us learn effective relaxation or activation techniques.
In the future, this means stress- and anxiety-related disorders could be treated in a playful way using a VR headset.
