Most of us have experienced writer’s block at some point, sitting down to write, paint or compose only to find we can’t get the creative juices flowing. Most frustrating of all, the more effort and thought we put into it, the harder it may become. Now, at least, neuroscientists might have found a clue about why it is so hard to force that creative spark. Researchers at Stanford University recently set out to explore the neural basis of creativity and came up with surprising findings. Their study, published May 28 in Scientific Reports, suggests the cerebellum, the brain region typically associated with movement, is involved in creativity. If so, the discovery could change our understanding of the neurological mechanisms behind some thought processes.
There is a scientific belief that the cerebral cortex is the part of the brain that “makes us human,” and that the two hemispheres of the cortex differentiate the creative thinkers from the logical thinkers (the “right-brained” from the “left-brained”). This has fostered the view that “neurological processes can be divided into “higher” cognitive functions and “lower” basic sensory-motor, functions,” says Robert Barton, an evolutionary biologist at Durham University in England who was not involved in this study—but the latest research calls that understanding into question.
