What is the impact of sounds on heart rate variability and cardiac autonomic regulation according to the pilot study described in the text?
Sounds have no impact on heart rate variability and cardiac autonomic regulation.
What is the heart rate variability (HRV)?
The perpetual heart rate oscillations around its mean value.
What is the central autonomic network (CAN)?
A network of neural cells in the brain.
What is the Polyvagal Theory?
A theory about the integration of neurocardiac regulation through n. vagus with the neural regulation of the middle ear muscles.
What is the impact of listening to music on the allostatic regulatory mechanisms according to the text?
Listening to music has a positive impact on the allostatic regulatory mechanisms.
