The fine dopamine line between creativity and schizophrenia

The fine dopamine line between creativity and schizophrenia
New research shows a possible explanation for the link between mental health and creativity. By studying receptors in the brain, researchers at the Swedish medical university Karolinska Institutet 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 pr bizarre associations are also shared by schizophrenics and healthy, highly creative people. And now the correlation between creativity and mental health has scientific backing. "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 Ullén.

Serotonin, Social Interaction and Making Decisions The role of specific neurotransmitters and neurotransmitter circuits in decision making is being explored in a variety of ways. Dopamine appears to have significant research support for a key role in making decisions related to reward.The role of serotonin in decision making is less well studied but also appears to be important. Robert Rogers, Ph.D. recently presented some of his lab's research at the Warren Frontiers in Neuroscience lecture in Tulsa, Oklahoma. (Additionally, I have reviewed and placed a link to a recent research manuscript from Dr. Rogers related to topic below.)Dr.

Chocolate - The Best Foods to Boost Your Mood: What to Eat to Fight Depression Get Topic Updates Slideshow Written by Nicole Kinsey and Medically Reviewed by Scott Pearlman, M.D. The cocoa in chocolate contains a source of serotonin, dopamine, and phenethylamine. These neurotransmitters are related to feelings of well-being and help in alleviating depression. (And enjoying a "treat" is a mood-lifter in itself!) Ecology of the Mind For thousands of generations we humans grew up in nature. Our teachers were flora and fauna and our textbooks thunderstorms and stars in the night sky. Our minds were like the forests, oases and deltas around which our cultures germinated: chaotic, wild, fecund. But in the last couple generations, we have largely abandoned the natural world, immersing ourselves in virtual realms. Today the synthetic environment rivals nature as a driving force in our lives, and the mental environment has become the terrain where our fate as humans will be decided. By emigrating from nature we’ve done something more than just move domiciles – we have fundamentally altered the context in which we live our lives.

Neuroscience, free will and determinism: 'I'm just a machine' What does this mean in terms of free will? "We don't have free will, in the spiritual sense. What you're seeing is the last output stage of a machine. There are lots of things that happen before this stage – plans, goals, learning – and those are the reasons we do more interesting things than just waggle fingers. But there's no ghost in the machine." The conclusions are shocking: if we are part of the universe, and obey its laws, it's hard to see where free will comes into it.

Two drugs show best treatment possibility for MS In massive news for neurology, The New England Journal of Medicine has published three important studies reporting that two new drugs for multiple sclerosis are more effective than existing treatments and can be taken in pill form. Multiple sclerosis is a bitch. It’s a neurological disorder where the immune system starts attacking myelin – the protective covering of nerves in the brain and spinal cord – leading to unpredictable attacks that typically leave the person a little more disabled each time. Problems can include movement difficulties, chronic pain, fatigue, cognitive problems, mood instability and impairments to the body’s automatic processes like digestion, bladder and bowel control. One problem with the the current treatments that try and slow down the disease itself, rather than just manage the effects, is that they all require regular injections or infusions via a drip. The studies that investigated these drugs were very impressive.

Losing weight Rosenhan experiment Rosenhan's study was done in two parts. The first part involved the use of healthy associates or "pseudopatients" (three women and five men, including Rosenhan himself) who briefly feigned auditory hallucinations in an attempt to gain admission to 12 different psychiatric hospitals in five different states in various locations in the United States. All were admitted and diagnosed with psychiatric disorders. After admission, the pseudopatients acted normally and told staff that they felt fine and had no longer experienced any additional hallucinations. All were forced to admit to having a mental illness and agree to take antipsychotic drugs as a condition of their release.
