Description:

Focusing on stepwise development of concepts, pattern recognition and integration with clinical practice, Reading EEGs: A Practical Approach, 2nd Edition, is an easy-to-use, readable guide to learning EEG for neurology residents, clinical neurophysiology fellows, and electroneurodiagnostic students and technologists. The emphasis on waveform recognition enables readers to interpret EEG findings accurately and place them in clinical context.  The new landscape format accommodates larger high-quality images for improved study, and the distinctive question-and-answer format is highly effective for review at all levels of training.
