Creativity is a cornerstone of what makes us human, yet the neural mechanisms underlying creative thinking are poorly understood. A recent surge of interest into the neural underpinnings of creative behavior has produced a banquet of data that is tantalizing but, considered as a whole, deeply self-contradictory. We review the emerging literature and take stock of several long-standing theories and widely held beliefs about creativity. A total of 72 experiments, reported in 63 articles, make up the core of the review. They broadly fall into 3 categories: divergent thinking, artistic creativity, and insight. Electroencephalographic studies of divergent thinking yield highly variegated results. Neuroimaging studies of this paradigm also indicate no reliable changes above and beyond diffuse prefrontal activation. These findings call into question the usefulness of the divergent thinking construct in the search for the neural basis of creativity. A similarly inconclusive picture emerges for studies of artistic performance, except that this paradigm also often yields activation of motor and temporoparietal regions. Neuroelectric and imaging studies of insight are more consistent, reflecting changes in anterior cingulate cortex and prefrontal areas. Taken together, creative thinking does not appear to critically depend on any single mental process or brain region, and it is not especially associated with right brains, defocused attention, low arousal, or alpha synchronization, as sometimes hypothesized. To make creativity tractable in the brain, it must be further subdivided into different types that can be meaningfully associated with specific neurocognitive processes.

“…Such a mechanism might also explain the finding of a positive association between alpha brain waves and verbal creativity (Fink, Grabner, Benedek, & Neubauer, 2006;Jausovec, 2000;Martindale & Hasenfus, 1978;Martindale & Hines, 1975). However, not all EEG studies find such an association (Danko, Shemyakina, Nagornova, & Starchenko, 2009;Molle, Marshall, Wolf, Fehm, & Born, 1999;Shemyakina & Danko, 2007) and the conditions under which it appears remain to be elucidated (Dietrich & Kanso, 2010).…”

Abstract:Previous studies found that performance on the remote associates test (RAT) improves after a period of incubation and that increased alpha brain waves over the right posterior brain predict the emergence of RAT insight solutions. We report an experiment that tested whether increased alpha brain waves during incubation improve RAT performance. Participants received two blocks of RAT items (RAT1 and RAT2), with the second block consisting of items that were not solved during the first block. Participants were randomly assigned to three groups, which were matched for their number of RAT1 solutions. Participants in an alpha-up neurofeedback group aimed to increase their alpha brain waves over the right posterior brain in between the two blocks, whereas participants in an alpha-down neurofeedback group aimed to decrease these same brain waves. A third group of participants did not perform neurofeedback and proceeded immediately from the first to the second block of RAT items. We found evidence for more RAT2 solutions in participants who interrupted their RAT performance with neurofeedback, especially in ones who showed high alpha brain waves during neurofeedback. These results are consistent with the notion that an alert but relaxed mental state, indexed by alpha brain waves, may aid the read out of an implicitly activated memory network of weak associates.

“…The time limits (short trials of only several seconds for each decision) led to the necessity for focused attention, high-speed processes and higher working memory load that could be accompanied by increases in beta activity [58][59][60]. In the condition of the absence of a long-term memory stereotypes during the creation of original definitions of words from different semantic fields, decreases in EEG spectral power in the beta-2 frequency band were observed in frontal areas, and an external induction of positive emotions led to generalized increases in the power of the beta-2 band [61]. These findings demonstrated the sensitivity of the high-frequency EEG bands to conditions of creative thinking and flexible changes in states depending on the task demands.…”

The study aimed to reveal task-related differences in story creation with and without the mental effort of overcoming self-induced stereotypes. Eighteen right-handed subjects (19.3 ± 1.1 years old) created stories. The subjects reported the formation of story plot stereotypes (as we call them: self-induced) during self-regulated creative production, which had to be overcome with the instruction to continue the story. Creative task fulfillment (without formed stereotypes-first stage of creation) was characterized by a decrease in the wave percentages of 9-10 Hz, 10-11 Hz and 11-12 Hz frequencies and EEG desynchronization (decreases in EEG spectral power) in the theta (4-8 Hz), alpha1 (8-10 Hz) and alpha2 (10-13 Hz) frequency bands in comparison with the REST (random episodic silent thought) state. The effortful creation task (with overcoming of self-induced stereotypes-second stage of creation) was characterized by increases in waves with frequencies of 9-10 Hz, 10-11 Hz, 11-12 Hz in temporal, occipital areas and pronounced EEG synchronization in alpha1,2 frequency bands in comparison with the free creation condition. It was also found, that the participants with the higher originality scores in psychological tests demonstrated increased percentage of high frequencies (11-12 Hz in comparison with those who had lower originality scores. Obtained results support the role of alpha and theta frequency bands dynamics in creative cognition.
