Shadlen and colleagues found that when asked to make a challenging decision, the brain does not use all the available information before deciding. In so doing, he hopes to unravel the mechanisms that underlie the brain’s most complex abilities. He has spent his career working to understand how signals sent by the brain’s billions of cells result in such decisions.
#Having an aha moment series
Shadlen, the most complex thoughts that the human brain can experience - such as love, grief, guilt or morality - can be ultimately be boiled down to a series of decisions, made by the brain, to engage with the outside world. But now, we’ve found a way to observe that moment in real time, and then apply those findings to our understanding of consciousness itself.”įor Dr. “How some of that information bubbles to the level of consciousness, however, remains an unsolved mystery. Zuckerman Mind Brain Behavior Institute and the paper’s senior author. “The vast majority of thoughts circling in our brains happen below the radar of conscious awareness, meaning that even though our brain is processing them, we are not aware,” said Michael Shadlen, MD, PhD, a Principal Investigator at Columbia’s Mortimer B. This research was reported today in Current Biology. Importantly, this study offers new hope that the biological foundations of consciousness may well be within our grasp.
The results of this study further suggest that this piercing of consciousness shares the same underlying brain mechanisms known to be involved in making far simpler decisions. Today’s findings in humans, combined with previous research, provide compelling evidence that this moment - this feeling of having decided - pierces consciousness when information being collected by the brain reaches a critical level. Columbia scientists have identified the brain’s ‘aha!’ moment - that flash in time when you suddenly become aware of information, such as knowing the answer to a difficult question.
