Thoughts on the Meaning of Brain Electrical Activity

Recordings of electrical brain activity have provided a rich field of data. These data are harvested at at least two scales of inquiry: scalp recordings from humans have accessed cognitive aspects of the mind/brain relationship, and microelectrode recordings in animals have delineated circuits involved in sensory and motor processes. As yet, there are few studies that have attempted to reconcile the findings obtained at these different scales. It is such reconciliation that we are attempting in experiments performed in our Center for Brain Research and Informational Sciences. A progress report follows.
