Creativity and the Brain
Creative thinking involves making new connections between different ideas, which is accomplished by cultivating divergent thinking skills and deliberately exposing yourself to new experiences and to learning. While research psychologists are interested in tapping innovative thinking, clinical psychologists sometimes encourage patients to use artistic expression as a way to confront difficult feelings.
Three key networks operate as a team to spark creativity in the brain, research suggests. The default mode network helps generate ideas, the executive control network evaluates them and propels them forward, and the salience network identifies which ideas are relevant and important. These networks may also influence one another via other feedback loops; for instance, the executive control network might tune the way the salience network scans internally, depending on the task at hand.
What is the default mode network?
The default mode network is the pattern of brain activity that occurs when people are not focused on the outside world. It’s the network that becomes active when the mind turns inward, as people daydream, rest, and reflect on the past or imagine the future. The default mode network can spark connections between different ideas, contributing to creative thought.
What is the salience network?
The salience network is a large system within the brain that helps to detect and filter important information from the environment, and then determine how to respond to that information. It scans for relevant signals, whether they contain sensory, cognitive, or emotional information. The salience network is rooted in the anterior insula and dorsal anterior cingulate cortex, but it contains nodes in other regions as well.
What is the executive control network?
The executive control network, or executive function, refers to the systems and processes that allow people to plan, monitor, and execute their goals. In the context of creativity, executive functioning monitors the observations, connections, and ideas that are generated, directs attention to particular ideas, and oversees decision-making in the context of a larger goal.
What is divergent thinking?
A hallmark of creativity, divergent thinking involves generating multiple ideas or solutions to a problem. It’s original and imaginative, exploring as many different connections as possible. By contrast, convergent thinking is converging onto a single, correct answer or solution, by analyzing the information available and judging which answer is best.
Does creativity arise from the right side of the brain?
The belief that the left hemisphere completely controls logic and the right brain governs creativity is largely a myth. Creativity and imagination involve communication between networks throughout both hemispheres, research shows. Those networks work together and collectively manipulate ideas, images, and symbols.
