Projet: Brain-heart coupling in emotional regulation

Présentation

Emotions have a profound impact on heart function, mediated by complex interactions between the brain and autonomic nervous system. Emotional states such as anxiety, fear, and anger can rapidly activate the sympathetic nervous system, increasing heart rate, blood pressure, and cardiac output. Key brain regions, including the prefrontal cortex, amygdala, and insula, regulate these emotional responses and their cardiovascular effects. Dysregulation of these circuits, particularly under chronic stress conditions, can lead to persistent sympathetic dominance, contributing to hypertension, arrhythmias, and increased cardiovascular disease risk.
