Summary

The stress response is mediated by the activation of the hypothalamo-pituitary-adrenal axis and the sympathetic nervous system, leading to glucocorticoid and catecholamines release respectively. This stress response is regulated by feedback loops, involving cortical and subcortical structures.

Non-invasive brain stimulation applied over the dorsolateral prefrontal cortex modulates the subcortical dopaminergic transmission at rest and can reduce the hormonal and cognitive alterations induced by stress. This study aims to investigate the Non-invasive brain stimulation -induced modulation of dopamine transmission in an acute stress situation.
