In the early 20th century scientists began to record brain activity using electrodes attached to the scalp. To their surprise, they saw that brain activity is characterized by slow and rapid ascending and descending signals which were subsequently called «brain waves».
Study shows how synchronization contributes to transmission, processing of information in the brain
