You know, its studies like this that make me a little weary of becoming a success through my creative ventures… I’m just sayin’ *pouts* New research shows a possible explanation for the link between mental health and creativity. By studying receptors in the brain, researchers at Karolinska Institute have managed to show that the dopamine system in healthy, highly creative people is similar in some respects to that seen in people with schizophrenia. High creative skills have been shown to be somewhat more common in people who have mental illness in the family. Creativity is also linked to a slightly higher risk of schizophrenia and bipolar disorder. Certain psychological traits, such as the ability to make unusual or bizarre associations are also shared by schizophrenics and healthy, highly creative people. And now the correlation between creativity and mental health has scientific backing. “We have studied the brain and the dopamine D2 receptors, and have shown that the dopamine system of healthy, highly creative people is similar to that found in people with schizophrenia,” says associate professor Fredrik Ullen from Karolinska Institutet’s Department of Women’s and Children’s Health, co-author of the study that appears in the journal PLoS ONE. Just which brain mechanisms are responsible for this correlation is still something of a mystery, but Dr Ullen conjectures that the function of systems in the brain that use dopamine is significant; for example, studies have shown that dopamine receptor genes are linked to ability for divergent thought. Dr Ullen’s study measured the creativity of healthy individuals using divergent psychological tests, in which the task was to find many different solutions to a problem. “The study shows that highly creative people who did well on the divergent tests had a lower density of D2 receptors in the thalamus than less creative people,” says Dr Ullen. “Schizophrenics are also known to have low D2 density in this part of the brain, suggesting a cause of the link between mental illness and creativity.” The thalamus serves as a kind of relay centre, filtering information before it reaches areas of the cortex, which is responsible, amongst other things, for cognition and reasoning. “Fewer D2 receptors in the thalamus probably means a lower degree of signal filtering, and thus a higher flow of information from the thalamus,” says Dr Ullen, and explains that this could a possible mechanism behind the ability of healthy highly creative people to see numerous uncommon connections in a problem-solving situation and the bizarre associations found in the mentally ill. “Thinking outside the box might be facilitated by having a somewhat less intact box,” says Dr Ullen about his new findings.

Tanka je granica između genijalnosti i shizofrenije Kreativnost je bliska ludilu, tvrde znanstvenici koji su proučavali kako funkcionira ljudski mozak Skeniranje mozga otkrilo je zapanjujuću sličnost u putevima misli kod visoko kreativnih ljudi kao i kod onih koji imaju shizofreniju. U obje grupe nedostajao je važan receptor koji filtrira i usmjerava misli. Moguće je kako ovaj proces omogućuje kreativnim ljudima da "razmišljaju izvan granica", tvrde stručnjaci sa švedskog Karolinska instituta. Kod nekih ljudi to pak vodi do bolesti. Neki od vodećih svjetskih umjetnika, pisaca i teoretičara imali su mentalne bolesti - nizozemski slikar Vincet van Gogh i američki matematičar Josh Nash samo su neki. Kreativnost se povezuje s povećanim rizikom od depresije, shizofrenije i bipolarnog poremećaja. Slično tome, ljudi koji imaju povijest mentalne bolesti u obitelji, također imaju veće šanse da budu kreativni. Profesor Fredrik Ullen vjeruje da njegova otkrića mogu objasniti zašto se to događa. Naime, proučavao je receptore dopamina u mozgu za koje stručnjaci vjeruju kako kontroliraju različite misli. Otkrio je da visoko kreativni ljudu koji su bili uspješni na testovima divergentnih misli, imaju manju gustoću dopaminskih receptora u talamusu, baš kao i oni koji pate od shizofrenije. "Manje ovih receptora u talamusu znači i manji stupanj filtriranja signala, te veći tok informacija iz talamusa", objašnjava profesor Ullen. On vjeruje kako ovaj tok necenzuriranih informacija potiče kreativnu iskru. Ovo bi moglo objasniti zašto kreativni ljudi uspijevaju vidjeti neobične veze u problematičnim situacijama, koje drugim ljudima promiču. Shizofreničari dijele istu sposobnost kako bi stvarali nove asocijacije, no kod njih to rezultira bizarnim i uznemirujućim mislima.
