What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

The On-Off Memory Switch

June 19, 2011, 9:55 AM

What's the Latest Development?

Scientists have created a device that successfully manipulates mice brains by controlling what they can remember. "The brain prosthesis marks the first time that researchers have been able to duplicate the brain's learning process, restoring memories that test rats were drugged to forget, and could offer hope for people with dementia. 'Flip the switch on, and the rats remember. Flip it off, and the rats forget,' said Theodore Berger of the University of Southern California's Viterbi School of Engineering's Department of Biomedical Engineering."

What's the Big Idea?

What will it take for this research to benefit humans? It is a long road, to be sure, but the ability to augment long-term memory could aid sufferers of memory loss due to dementia, stroke or brain injury. "In normal rats, 'the device could actually strengthen the memory being generated internally in the brain and enhance the memory capability,' said the study published in the Journal of Neural Engineering. The team hopes to test the device in monkeys next, in the hope it could one day help people who suffer from memory loss due to dementia, stroke or brain injury."
