Task: Answer Verification
Input (English): Question: Does transcranial magnetic stimulation reveal cortical hyperexcitability in episodic cluster headache?
Answer: We investigated cortical excitability in episodic cluster headache by using transcranial magnetic stimulation, providing evidence of cortical hyperexcitability in patients both inside and outside bout. We suggest that an abnormal state of cortical excitability could be involved in the pathophysiology of the disease.
Output (English): yes
