Bad news: Human brain may have reached full capacity

Simon Laughlin, professor of neurobiology, said: ‘We have demonstrated that brains must consume energy to function and that these requirements are sufficiently demanding to limit our performance and determine design.

‘Far-reaching powers of deduction demand a lot of energy because for the brain to search out new relationships it must constantly correlate information from different sources.

‘Such energy demands mean there is a limit to the information we can process.’
