Creativity is one of the most important human qualities. Innovative behaviours have been described in other animals, but they are difficult to compare with the richness and variety of human creativity, so complex that it is difficult to analyse with current neuroscientific methods. The number of studies on this field has increased in the last years, but they are scarce if we compare them to other cognitive domains like language or memory. Current evidence suggests
that creativity is a global brain function, without clear support for hemispheric lateralization or the critical role of any brain area or neuronal network. Like other complex brain functions, creativity seems to require the integration of information from different brains regions, with a consistent involvement of the frontal lobes, parietal and temporal association cortices. We present a short review on the neuroscience of creativity, and explore the possible relationship between creativity and neurological or psychiatric diseases.
