<P> According to Vandervert, the details of creative adaptation begin in "forward" cerebellar models which are anticipatory / exploratory controls for movement and thought . These cerebellar processing and control architectures have been termed Hierarchical Modular Selection and Identification for Control (HMOSAIC). New, hierarchically arranged levels of the cerebellar control architecture (HMOSAIC) develop as mental mulling in working memory is extended over time . These new levels of the control architecture are fed forward to the frontal lobes . Since the cerebellum adaptively models all movement and all levels of thought and emotion, Vandervert's approach helps explain creativity and innovation in sports, art, music, the design of video games, technology, mathematics, the child prodigy, and thought in general . </P> <P> Essentially, Vandervert has argued that when a person is confronted with a challenging new situation, visual - spatial working memory and speech - related working memory are decomposed and re-composed (fractionated) by the cerebellum and then blended in the cerebral cortex in an attempt to deal with the new situation . With repeated attempts to deal with challenging situations, the cerebro - cerebellar blending process continues to optimize the efficiency of how working memory deals with the situation or problem . Most recently, he has argued that this is the same process (only involving visual - spatial working memory and pre-language vocalization) that led to the evolution of language in humans . Vandervert and Vandervert - Weathers have pointed out that this blending process, because it continuously optimizes efficiencies, constantly improves prototyping attempts toward the invention or innovation of new ideas, music, art, or technology . Prototyping, they argue, not only produces new products, it trains the cerebro - cerebellar pathways involved to become more efficient at prototyping itself . Further, Vandervert and Vandervert - Weathers believe that this repetitive "mental prototyping" or mental rehearsal involving the cerebellum and the cerebral cortex explains the success of the self - driven, individualized patterning of repetitions initiated by the teaching methods of the Khan Academy . The model proposed by Vandervert has, however, received incisive critique from several authors . </P> <P> Creativity involves the forming of associative elements into new combinations that are useful or meet some requirement . Sleep aids this process . REM rather than NREM sleep appears to be responsible . This has been suggested to be due to changes in cholinergic and noradrenergic neuromodulation that occurs during REM sleep . During this period of sleep, high levels of acetylcholine in the hippocampus suppress feedback from the hippocampus to the neocortex, and lower levels of acetylcholine and norepinephrine in the neocortex encourage the spread of associational activity within neocortical areas without control from the hippocampus . This is in contrast to waking consciousness, where higher levels of norepinephrine and acetylcholine inhibit recurrent connections in the neocortex . It is proposed that REM sleep adds creativity by allowing "neocortical structures to reorganize associative hierarchies, in which information from the hippocampus would be reinterpreted in relation to previous semantic representations or nodes ." </P> <P> Some theories suggest that creativity may be particularly susceptible to affective influence . As noted in voting behavior, the term "affect" in this context can refer to liking or disliking key aspects of the subject in question . This work largely follows from findings in psychology regarding the ways in which affective states are involved in human judgment and decision - making . </P>
