  • Brain is ten times more active than previously measured

Researchers have found the human brain to be tenfold times quicker than it was thought to be in erstwhile times.

A novel study could change the way scientists think about the human brain. Radically different approaches to treating neurochemical diseases could be the wave of the future thanks to this scheme.

Spikes along the dendrites allow connectivity and communication to take place. These somatic spikes are basically responsible for memory traces. These dendrites are not mechanical agents.

They are in fact quite active in their operations. They also form over 90% of the brain tissue. The spikes in dendrites are binary in nature. However now we also know that dendrites can perform both on a digital and an analog basis.

What all this means is that the brain could actually have up to ten times the capacity it is thought to possess right now. The spikes were five times more frequent in the lab rats when they were sleeping. When they were engaged in exploration, their spikes increased upto ten times the usual rate.

Previous models had supposed that learning takes place when the cell bodies of two neurons are in the active phase. The new research shows that learning takes place both when the neurons are active and so are the dendrites.

The learning experience is thus a very flexible phenomenon. It shows the malleability of the mind. From this study, the supercomputers of the future may get built. They will mimic the human mind in its marvelous architectonics.

The research is published in the March 9 issue of the journal Science.
