Scientists recently said that human brain can retain 470 million books together.
The study of the capacitance of cells containing brain data has been conducted by some US scientists.
They discovered, on average, a synaptic data retention capacity of 4.7 bytes. This means that human brain data retention capacity is 1 petabyte or 1,000,000,000,000,000 bytes.
One petabite equal to twenty-four drawers is the exclusive steel office cabinet, which is full of books or 13.3 years of HD TV recording or 470 million books or 670 million web pages.
The human brain is able to contain this amount of information at any time, but in reality the brain information is much smaller.
Nevertheless, the head of the researcher Terry Sjensky said, "This is a breakthrough in the neuroscience. Our brain can contain 10 times more information than what was previously said about the capacity of the brain.
