Task: Answer Verification
Input (English): Question: Is cardiovascular reactivity to mental stress affected by alpha2-adrenoreceptor activation or inhibition?
Answer: Cardiovascular reactivity to mental stress is not related to pharmacologically manipulated tonic central sympathetic nervous system activity by alpha2-adrenergic agonists and antagonists. These results do not support the assumption that cardiovascular reactivity is an index of tonic central sympathetic nervous system activity.
Output (English): no
