Explanation:

Research participants were asked to identify a word that would form a compound word or phrase with each of three other words. Solutions that occurred with sudden insight were accompanied by a burst of activity in the brain's right temporal lobe.

The temporal lobe is one of the four brain lobes. Associated with a number of sensory functions, particularly hearing and speech perception, the temporal lobe is located near the base of the brain on either side of the cerebral cortex. The temporal lobe’s primary role is to integrate and interpret sensory input, both audio and visual, though it also plays a significant role in several other functions. Long-term explicit memory is regulated by the hippocampus, which is housed in the temporal lobe and aids in both memory and spatial navigation. Other functions affected by the temporal lobe include language comprehension, personality, and behavior, particularly sexual and social behavior. Libido depends on the temporal lobe, and so do personality traits such as irritability and agitation, which are produced in the temporal lobe.
