“…From these myriad perspectives have emerged several attempts designed to capture the neuroscience of creativity, based largely on data gleaned from neurological and psychiatric patients and largely confined to artistic expression (Pollack et al, 2007). Indeed, de novo artistic expression have been associated with left fronto-temporal (Finkelstein et al, 1991) and right temporal lobe epilepsy (Mendez, 2005), several case studies of fronto-temporal lobe dementia (FTLD) (Miller et al, 1998, 2000; Thomas Anterion et al, 2002), a case of Parkinson's disease treated with dopaminergic agonists (Schrag and Trimble, 2001), and a single case of subarachnoid hemorrhage (Lythgoe et al, 2005). Miller postulates that the selective atrophy of the anterior temporal and basal frontal lobes that accompanies FTD may reduce inhibition of the more posteriorly located visual systems, resulting in the patients' heightened interest in artistic works (Miller et al, 1998).…”

Creativity is a vast construct, seemingly intractable to scientific inquiry—perhaps due to the vague concepts applied to the field of research. One attempt to limit the purview of creative cognition formulates the construct in terms of evolutionary constraints, namely that of blind variation and selective retention (BVSR). Behaviorally, one can limit the “blind variation” component to idea generation tests as manifested by measures of divergent thinking. The “selective retention” component can be represented by measures of convergent thinking, as represented by measures of remote associates. We summarize results from measures of creative cognition, correlated with structural neuroimaging measures including structural magnetic resonance imaging (sMRI), diffusion tensor imaging (DTI), and proton magnetic resonance spectroscopy (1H-MRS). We also review lesion studies, considered to be the “gold standard” of brain-behavioral studies. What emerges is a picture consistent with theories of disinhibitory brain features subserving creative cognition, as described previously (Martindale, 1981). We provide a perspective, involving aspects of the default mode network (DMN), which might provide a “first approximation” regarding how creative cognition might map on to the human brain.

“…We found 35 relevant papers reporting the degradation, emergence, preservation or improvement of creative expression in 53 patients after the onset of different neurological diseases (see Table 1): 19 patients with temporal variant FTD (semantic dementia), 10 patients with behavioral variant FTD, eight patients with Alzheimer's disease, four patients with primary progressive non-fluent aphasia, and 12 patients with various neurological diseases (Espinel, 1996; Miller et al, 1998, 2000; Crutch et al, 2001; Thomas-Anterion et al, 2002, 2010; Kleiner-Fisman et al, 2003; Mell et al, 2003; Mendez and Perryman, 2003; Annoni et al, 2005; Fornazzari, 2005; Lythgoe et al, 2005; Serrano et al, 2005; Chatterjee et al, 2006; Drago et al, 2006a,b; Budrys et al, 2007; Finney and Heilman, 2007; Midorikawa et al, 2008; Seeley et al, 2008; Liu et al, 2009; Thomas-Anterion, 2009; Chakravarty, 2011; Chatterjee et al, 2011; van Buren et al, 2013; Galarza et al, 2014; Takahata et al, 2014). All reported patients with temporal FTD ( n = 19) presented the emergence ( n = 11), increase ( n = 2), or preservation ( n = 6) of creative production but no degradation of artistic abilities (Miller et al, 1996, 1998; Edwards-Lee et al, 1997; Drago et al, 2006b; Wu et al, 2013).…”

The effects of Alzheimer's disease on artistic production were more heterogeneous, with observations of both increase (Fornazzari, 2005; Chakravarty, 2011) and degradation (Cummings and Zarit, 1987; Crutch et al, 2001; Serrano et al, 2005; van Buren et al, 2013).…”

Concepts from cognitive neuroscience strongly suggest that the prefrontal cortex (PFC) plays a crucial role in the cognitive functions necessary for creative thinking. Functional imaging studies have repeatedly demonstrated the involvement of PFC in creativity tasks. Patient studies have demonstrated that frontal damage due to focal lesions or neurodegenerative diseases are associated with impairments in various creativity tasks. However, against all odds, a series of clinical observations has reported the facilitation of artistic production in patients with neurodegenerative diseases affecting PFC, such as frontotemporal dementia (FTD). An exacerbation of creativity in frontal diseases would challenge neuroimaging findings in controls and patients, as well as the theoretical role of prefrontal functions in creativity processes. To explore this paradox, we reported the history of a FTD patient who exhibited the emergence of visual artistic productions during the course of the disease. The patient produced a large amount of drawings, which have been evaluated by a group of professional artists who were blind to the diagnosis. We also reviewed the published clinical cases reporting a change in the artistic abilities in patients with neurological diseases. We attempted to reconcile these clinical observations to previous experimental findings by addressing several questions raised by our review. For instance, to what extent can the cognitive, conative, and affective changes following frontal damage explain changes in artistic abilities? Does artistic exacerbation truly reflect increased creative capacities? These considerations could help to clarify the place of creativity—as it has been defined and explored by cognitive neuroscience—in artistic creation and may provide leads for future lesion studies.

Subsequent systematic study of artistic ability associated with the various dementias found no general increase in creativity to be linked with FTD, with the authors noting that “despite the existence of these isolated patients with increased artistic production, however, apathy leading to diminished creativity is more clinically typical of patients with FTD, suggesting that these case studies may be the exception rather than the rule” (Rankin et al,2007).…”

Creativity has long been a construct of interest to philosophers, psychologists and, more recently, neuroscientists. Recent efforts have focused on cognitive processes likely to be important to the manifestation of novelty and usefulness within a given social context. One such cognitive processdivergent thinking -is the process by which one extrapolates many possible answers to an initial stimulus or target data set. We sought to link well established measures of divergent thinking and creative achievement (Creative Achievement Questionnaire -CAQ) to cortical thickness in a cohort of young (23.7 ± 4.2 years), healthy subjects. Three independent judges ranked the creative products of each subject using the consensual assessment technique (Amabile, 1982) from which a "composite creativity index" (CCI) was derived. Structural magnetic resonance imaging was obtained at 1.5 Tesla Siemens scanner. Cortical reconstruction and volumetric segmentation were performed with the FreeSurfer image analysis suite. A region within the lingual gyrus was negatively correlated with CCI; the right posterior cingulate correlated positively with the CCI. For the CAQ, lower left lateral orbitofrontal volume correlated with higher creative achievement; higher cortical thickness was related to higher scores on the CAQ in the right angular gyrus. This is the first study to link cortical thickness measures to psychometric measures of creativity. The distribution of brain regions, associated with both divergent thinking and creative achievement, suggests that cognitive control of information flow among brain areas may be critical to understanding creative cognition.
