Why our brains may be 100 times more powerful than believed

• by Michael Franco

The finding implies that our brains are both analog and digital computers and could lead to better ways to treat neurological disorders.

The focus of the study was the dendrites, long branch-like structures that attach to a roundish body called the soma to form neurons. It was previously believed that dendrites were nothing more than conduits that sent spikes of electrical activity generated in the soma to other neurons. But the study has shown that the dendrites themselves are highly active, sending spikes of their own at a rate 10 times that previously believed.

The finding runs counter to the long-held belief that somatic spikes were the main way we learn and form memories and perceptions.
