2. Basic Electronics for Neurology Electricity and basic circuit theory Filters and amplifiers Digital signal analysis Displays Electrodes Artifacts and noise Electrical safety

3. Why do I need to know this? Large part of the clinical neurophysiology boards. Might be nice to understand how your equipment works. I make money from the sale of the definitive text… Essentials of Clinical Neurophysiology, www.elsevier.com

4. ABPN: Clinical neurophysiology Board certified in neurology, child neurology, or psychiatry Finished 1 year of ACGME-approved training in CN, not during residency. May be part time (at least 1/2 time) Certification: 5 hours Re-certification: 3 hours

5. ABPN: Clinical neurophysiology Core neurophysiology (18%) Basic and applied neurophysiology EEG (38%) Methods, Basic patterns, variants Clinical correlations EMG (38%) Methods, Basic patterns Clinical correlations Sleep (6%)
