The EEG has shaped researchers’ understanding of cognition for everything from perception to memory
From Diagnosing Brain Disorders to Cognitive Enhancement, 100 Years of EEG Have Transformed NeuroscienceSince its first use, the EEG has shaped researchers’ understanding of cognition, from perception to memory. It has also been important for diagnosing and guiding treatment of multiple brain disorders, including epilepsy..

Since the discovery of EEG, researchers have shown that neural activity oscillates at specific frequencies. In his initial EEG recordings in 1924, Berger noted the predominance of oscillatory activity that cycled eight to 12 times per second, or 8 to 12 hertz, namedNeural oscillations are thought to be important for effective communication between specialized brain regions.
Noninvasive brain stimulation methods can target frequencies of interest. For example, my team’s ongoing research found that brain stimulation at theta frequency can, including how people perceive the world around them, how they focus their attention, how they communicate through language and how they process emotions.
