It has been known for nearly 20 years that slow, synchronous electrical waves in the brain during deep sleep support the formation of memories. Why that is, was previously unknown. How do permanent ...

It has been known for nearly 20 years that slow, synchronous electrical waves in the brain during deep sleep support the formation of memories. Why that is was previously unknown. Now, a team of ...

When electrical activity travels across the brain, it moves like ripples on a pond. The motion of these "brain waves," first observed in the 1920s, can now be seen more clearly than ever before thanks ...

Hans Berger recorded the first human EEG in 1924. EEG records electrical activity via 16–25 scalp electrodes. Focal “slowing” in brain waves can indicate tumors or lesions. Patients must avoid ...
