Brain Myth – Computer-Head

Brains are like computers . . . not
We speak of the brain’s processing speed, its storage capacity, its parallel circuits, inputs and outputs. The metaphor fails at pretty much every level:

1.  The brain doesn’t have a set memory capacity that is waiting to be filled up

2.  It doesn’t perform computations in the way a computer does

3.  Basic visual perception isn’t a passive receiving of inputs – we actively interpret, anticipate and pay attention to different elements of the visual world.

“There’s a long history of likening the brain to whatever technology is the most advanced, impressive and vaguely mysterious. Descartes compared the brain to a hydraulic machine. Freud likened emotions to pressure building up in a steam engine. The brain later resembled a telephone switchboard and then an electrical circuit before evolving into a computer; lately it’s turning into a Web browser or the Internet. These metaphors linger in clichés: emotions put the brain “under pressure” and some behaviors are thought to be “hard-wired.”

March 12-18, 2018 is Brain Awareness Week (BAW) is a nationwide effort organized by the Dana Alliance for Brain Initiatives and the Society for Neuroscience to promote the public and personal benefits of brain research.
