One study found that the human brain can hold up to 10 times more information than previously thought. All that being said, scientists now believe that the power of the human brain is about a petabyte. … Humans are more powerful than computers in such tasks. Brain thinking can be more powerful than computers – microscopic branches of brain cells that were once thought to act as wires can actually act as minicomputers, researchers say. The computer is the brain. The human brain has about 1 quadrillion – 1 million billion – about 100 trillion neurons whose connections make these cells wiring together. Neurons act as relay stations for each electrical signal. The heart of each neuron is called a soma – the only thin wire-like fiber known as an axon that stays away from the soma to carry the nerve signal away from the neuron, while many short branches are called dendrites which carry the nerve signals from the other end of the soma.
Now scientists have discovered that dendrites can be more than passive wiring; In reality, they can actively process information. “Suddenly it seems that the processing power of the brain has increased much more than we initially thought,” said Spencer Smith, a neuroscientist at the University of North Carolina at Chapel Hill, in a statement. Electrical spike action is the neurons that are commonly used to create electrical spikes. However, previous studies have discovered that many of the same molecules that support the same electrical spikes are also present in dendrites, and studies of brain tissue have shown that dendrites can use these molecules themselves to create these spikes.
