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.

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. The original page that I began building this compiled information from is (*archived copy*) The information in green is from this original page. If you want to redistribute this, please include the Bibliography page as well -- the original sources deserve their reference.

Sculpture - News January 30 A new multi-part, multi-material thing: And the pieces are like this: Like the Tetrabox piece last month, which went well and is now in stock, this one is held together with rare-earth magnets and improved with glow-in-the-dark glass. December 24 Thanks again for a great holiday season! And since I just realized I didn't announce it here, for completeness: Behold the Glow Cuttlefish Bottle Opener. December 10 This year's factory seconds sale is on. Update: Well, that lasted about two days. December 2 Why so serious? WhaleSnail In other news, I set up gift certificates through Paypal: December 2 Christmas Shipping When to order to be reasonably sure your package will arrive on time. Our last shipping day before Christmas is Monday the 23rd (cutoff at noon Eastern time!) Best wishes for a great holiday season! October 22 I made a sculpture that comes in four pieces and assembles to make sort of a box. I don't have stock of this yet – just my proof – but I've ordered parts for more. August 26

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.

Security Cameras, Surveillance Cameras, Outdoor Wireless Camera Colour my world Colour does not exist. Not out in the world at any rate. All that exists in the world is a smooth continuum of light of different wavelengths. Colour is a construction of our brains. Colour discrimination begins with the absorption of light of different wavelengths. Colour information only arises by comparing the responses of multiple cone cells. The L/M system evolved much more recently, due to a gene duplication that occurred in the lineage of Old World primates, probably around 40 million years ago. All of this raises an important question – how are the inputs to these different cone cells compared? This has been known for quite a long time now. The new study by Field and colleagues worked out in breathtaking detail the circuitry of the retina at a cellular level. Their results reveal exactly such a bias and further show that it cannot be explained simply by random clumping of L or M cones in the photoreceptor array. Amazingly, this may extend to humans as well.

The Thirteen Heavens The Thirteen Tones of Evolution The levels of consciousness developed by each Underworld are developed according to a common pattern. The Maya used to describe this by the notion that a special deity or divine force ruled each of the Thirteen Heavens of the various Underworlds and from the Aztecs we have information about what these deities were: General scheme of the divine forces ruling the Thirteen Heavens or the Seven days and Six nights of divine creation The interesting thing about these thirteen deities ruling the thirteen heavens is that if we look at every other deity, the seven with odd-numbers above, we find that they are forces that nurture the development of a seed. The History of the Telecommunications The Development of the Telecommunications Since the strongest creative pulses, displaying the most important steps forward in consciousness, appear during the Seven odd-numbered Heavens we may safely assume that this is what has given rise to the holiness of the number Seven.

Grammatika by Troy A Peterson We're making an app, 3 videos and a poster that will help you turn your guitar, bass, piano or ukelele into a musical light saber by connecting it to the Force. Well, the Circle of Fifths and Nashville #'s. You'll still need a music teacher to become a Jedi but the app, vids and poster are guaranteed to raise your musiclorean levels. By backing this Kickstarter you'll help cover the costs for: Video 1 How to Play the Grammatika/Music Theory in Plain English 1. Video 2 Turn plain English into Musical Nomenclature 1. Video 3 1. The app itself combines the Circle of Fifths and Scale Scale Degrees and creates and a fingering chart that will turn your instrument into a light saber.

Illusions of bodily awareness adapted for the pub : Neurophilosophy DO you think that you perceive your body and the world around you as they really are? If your answer to that question is “yes”, then think again. Our perceptions are little more than the brain’s best guess of the nature of reality, constructed from fragments of information it receives through the senses. This is demonstrated by visual illusions, which produce discrepancies between physical reality and what we see of it, and by illusions of bodily awareness, which distort the way we perceive our bodies. Psychologists and neuroscientists have long used illusions to investigate the mechanisms underlying perception. The first illusion that I have adapted for the pub is the rubber hand illusion. Simply manipulating the sensory information about the hand in this way causes the subject to perceive the felt sensations as originating in the fake hand and not their real one.
