A human brain could hold as much information as the entire internet, a new study finds.
Human memory capacity is in the petabyte range, researchers at the Salk Institute have now found.
This is ten times larger than was previously thought.
Professor Terry Sejnowski, the study’s first author, said:
“This is a real bombshell in the field of neuroscience.
We discovered the key to unlocking the design principle for how hippocampal neurons function with low energy but high computation power.
Our new measurements of the brain’s memory capacity increase conservative estimates by a factor of 10 to at least a petabyte, in the same ballpark as the World Wide Web.”
The conclusions come from an analysis of the brain’s synapses.The picture above shows a synapse between an axon (green) and dendrite (yellow).
