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.

How Exercise Works on the Brain to Reduce Stress & Anxiety

What's the Latest Development?

Princeton scientists have found that mice are less anxious about experiencing stressors, such as entering a pool of cold water, when they are allowed regular exercise. The report, recently published in the Journal of Neuroscience, explains the experiment and how the "[mice's] brains exhibited a spike in the activity of neurons that shut off excitement in the ventral hippocampus, a brain region shown to regulate anxiety." Princeton's Elizabeth Gould said that by helping researchers pinpoint brain cells and regions important to anxiety regulation, the study will work to create a better understanding of human anxiety disorders and help treat them in the future.

What's the Big Idea?

A larger trend demonstrated by the study, according to Gould, is the brain's ability to adapt and tailor its own processes to an organism’s lifestyle or surroundings. "A higher likelihood of anxious behavior may have an adaptive advantage for less physically fit creatures. Anxiety often manifests itself in avoidant behavior and avoiding potentially dangerous situations would increase the likelihood of survival, particularly for those less capable of responding with a 'fight or flight' reaction, she said." Understanding how the brain regulates anxious behavior could yield potential clues about helping people with anxiety disorders.
