The neuroscientific study of hallucinogens

The neuroscientific study of hallucinogens
Recently, an important and landmark paper was published in PLoS ONE (hooray open access!) titled, "Investigating the Mechanisms of Hallucinogen-Induced Visions Using 3,4-Methylenedioxyamphetamine (MDA): A Randomized Controlled Trial in Humans". It sounds daunting, but trust me, it's a very cool, approachable study. Now, in the spirit of full-disclosure, the lead author Dr. Matthew Baggott (hereafter referred to as "Matt"), is a friend of mine from grad school and he's been kind enough to grant me a very thorough interview for this post. At the bottom of this post you will also find an hour-long YouTube interview with Matt about his research as part of "Dr. That said, my real-life association with Matt is not biasing my opening statement; his paper is truly landmark for many reasons. [T]here is a staggering diversity of hallucinogens out there: hundreds of compounds, each affecting different combinations of binding sites in the brain. I think you hit the nail on the head.

The fine dopamine line between creativity and schizophrenia | Sc 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. "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.

Mind-reading light helps you stay in the zone - tech - 17 December 2013 A device that uses light to measure your level of concentration can tell when you’re bored or overworked, and can tweak tasks to keep you focused Editorial: "Leaps of discovery reveal humanity's place in the world" WITH a click of a mouse, I set a path through the mountains for drone #4. It's one of five fliers under my control, all now heading to different destinations. Routes set, their automation takes over and my mind eases, bringing a moment of calm. But the machine watching my brain notices the lull, decides I can handle more, and drops a new drone in the south-east corner of the map. The software is keeping my brain in a state of full focus known as flow, or being "in the zone". The system monitors the workload by pulsing light into my prefrontal cortex 12 times a second. Dan Afergan, who is running the study at Tufts University in Medford, Massachusetts, points to an on-screen readout as I play. Afergan doesn't plan to be confined to the lab for long either.

Stimulating brain with electricity aids learning speed 20 September 2011Last updated at 11:52 By Leila Battison Science reporter The brain can change its structure in response to experience and practice Electrically stimulating the brain can help to speed up the process of learning, scientists have shown. Applying a small current to specific parts of the brain can increase its activity, making learning easier. Researchers from the University of Oxford have studied the changing structure of the brain in stroke patients and in healthy adults. Prof Heidi Johansen-Berg presented their findings at the British Science Festival in Bradford. The team at Oxford has been conducting research into how the structure of the brain changes in adulthood, and in particular what changes occur after a stroke. They have used an approach called functional MRI to monitor activity in the brain as stroke patients re-learn motor skills that were lost as a result of their illness. Increasing activity The studies employ a variant of the same MRI scan used in hospitals

Falling in love is 'more scientific than you think,' according to new study by SU professor Falling in love is 'more scientific than you think,' according to new study by SU professor October 18, 2010 Donna Adamo(315) 443-5172 A new meta-analysis study conducted by Syracuse University Professor Stephanie Ortigue is getting attention around the world. Ortigue is an assistant professor of psychology and an adjunct assistant professor of neurology, both in The College of Arts and Sciences at Syracuse University. Results from Ortigue’s team revealed when a person falls in love, 12 areas of the brain work in tandem to release euphoria-inducing chemicals such as dopamine, oxytocin, adrenaline and vasopression. The findings beg the question, “Does the heart fall in love, or the brain?” “That’s a tricky question always,” says Ortigue. Other researchers also found blood levels of nerve growth factor, or NGF, also increased. The study also shows different parts of the brain fall for love.

Create Digital Motion » Code as Art: Generative Visual Inspirati Generative works from Keith Peters, on his new Art from Code site. As code literacy improves and coding tools like Processing and Flash make it easier to produce stunning visual results, the line between the coder/hacker and digital artist, and more conventional artists, is blurring fast. The next trend: networks and blogs on which people share not just their work, but the code behind it. The Flash Virtuoso, and Galleries vs. Keith Peters, aka BIT-101, has been instrumental in the Flash community in advocating digital art and animation. I owe a huge debt to Keith, as I got into generative coding entirely through his books, before later going on to discover Processing. Interestingly, the relationship between code and art is an imperfect one. Keith writes on his blog: I want this site to be more about the images than an open source code repository. Also, interestingly, Keith notes he often works with code directly on the timeline — something that’s not possible in Processing. OpenCode

Brainwave/Cymatic Frequency Listing This is a listing of frequencies that various parties have claimed can affect the human mind or body in some way. The following sorts of frequencies are included : Brainwave Frequencies - These are frequencies associated with various mental states. Using brainwave entrainment, you can coax your brainwaves to a certain frequency, and in doing so, achieve the mental state associated with that frequency.

Researchers develop ‘camera’ that will show your mind Among the great enigmas of human existence, few have proven so intractable as the human brain. Neuroscientist V.S. Ramachandran says our current understanding of the body's most complex organ approximates what we knew about chemistry in the 19th century: in short, not much. On a scale of 100, estimates Toronto psychiatrist Colin Shapiro, our comprehension of how the brain actually functions ranks at a lowly 2. Now, two Toronto doctors, a general practitioner and a medical biophysicist, are laying claim to a research innovation that could expand our knowledge exponentially. Using one of the earliest imaging technologies, the electroencephalograph (EEG), Mark Doidge and Joseph Mocanu have written software that creates dynamic, real-time, three-dimensional colour movies of the brain. If their research is validated, it could revolutionize neuroscience - and, not incidentally, make them a fortune. "We usually think of cameras as looking out at the world," Dr. Dr. Dr. Dr. That, conceded Dr.

Scientists extract images directly from brain ::: Pink Tentacle Researchers from Japan's ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person's mind and display them on a computer monitor, it was announced on December 11. According to the researchers, further development of the technology may soon make it possible to view other people's dreams while they sleep. The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Then, when the test subjects were shown a completely new set of images, such as the letters N-E-U-R-O-N, the system was able to reconstruct and display what the test subjects were viewing based solely on their brain activity. For now, the system is only able to reproduce simple black-and-white images. "These results are a breakthrough in terms of understanding brain activity," says Dr. The research results appear in the December 11 issue of US science journal Neuron. [Source: Chunichi]

Understanding Why Pornography Addiction is a Brain Disease “One ring to rule them all, One Ring to find them. One Ring to bring them all, and in the darkness bind them. In the Land of Mordor where the shadows lie.” -J.R.R. Until the general public becomes more informed about the reality of how pornography impacts the human brain it will continue to be looked upon as a moral weakness or a form of mere entertainment. Pornography addiction is the most difficult addiction to treat because it hits at the very core of our humanity. Throughout my professional carrier I have spent countless hours treating those with chemical dependency addictions such as with alcohol, heroin/opiates, cocaine, methamphetamine, marijuana etc. Our brains are made up of tiny chemicals called neurotransmitters. The physical/chemical brain has a tremendous capacity to gain control of the mind. In essence, the only difference between a heroin or cocaine addict is the way the drug enters the system. “I am sick to my core by virtue of my indulgence in pornography.

Scientists Can Read Minds with Brain Scans By scanning your brain, scientists can tell what memory you are recalling. Scientists have made impressive gains recently when it comes to reading minds. For instance, through brain scans, researchers can tell what number a person has just seen, figure out what letters a person wants to type, and determine where people were standing within virtual reality environments. To see if they could discern even more complex information during mind-reading, scientists more recently had 10 volunteers watch three films, each seven-seconds long and featuring a different actress in a fairly similar everyday scenario on a typical urban street. For instance, in one movie, a woman rifled through her purse to find an envelope she then dropped into a mailbox, while in another, an actress finished her cup of coffee, which she then dropped into a trashcan. In these experiments, the researchers exposed volunteers to movies roughly an hour before scanning took place.
