<p>I made contact with the head of the neurology department from my local university 5 days ago, and he told me that he would check to see if he could find me any research opportunities. He has not contacted me since, and I am wondering if I should contact him today about it as a reminder. Any advice?</p>
<p>I would wait a week (so you are almost there) then send a nice email reminder.</p>
<p>Thank you!</p>
