Speculative questions from research into mental illness

Could depression be an infectious disease? Might hallucinogenic mushrooms be an effective treatment for depression (New York Times link)? Do antipsychotic drugs hinder long-term recovery from episodes of schizophrenia?

hyperconnected: your brain on shrooms

How Tripping On Mushrooms Changes The Brain - "New research [pdf] suggests that psilocybin, the main psychoactive ingredient in magic mushrooms, sprouts new links across previously disconnected brain regions, temporarily altering the brain's entire organizational framework." [more inside]

Migrating cerebral lesions indicate sparganosis

"The patient tested negative for HIV, tuberculosis, lime disease, syphilis, coccidioides, histoplasma and cryptococcus." After four years of MRIs, a person's mysterious headaches, seizures and altered sense of smell and memory are diagnosed as a tapeworm growing throughout his brain.

запомнить практики запоминать практика запоминать практику

Time after time, professors in mathematics and the sciences have told me that building well-ingrained chunks of expertise through practice and repetition was absolutely vital to their succes Understanding doesn’t build fluency; instead, fluency builds understanding. In fact, I believe that true understanding of a complex subject comes only from fluency.

If we're not in pain, we're not alive

You invest so much in it, don't you? It's what elevates you above the beasts of the field, it's what makes you special. Homo sapiens, you call yourself. Wise Man. Do you even know what it is, this consciousness you cite in your own exaltation? Do you even know what it's for?
Dr. Peter Watts is no stranger to MetaFilter. But look past his sardonic nuptials, heartbreaking eulogies, and agonizing run-ins with fascists (and fasciitis) and you'll find one of the most brilliant, compelling, and disquieting science fiction authors at work today. A marine biologist skilled at deep background research, his acclaimed 2006 novel Blindsight [full text] -- a cerebral "first contact" tale led by a diverse crew of bleeding-edge post-humans -- is diamond-hard and deeply horrifying, wringing profound existential dread from such abstruse concepts as the Chinese Room, the Philosophical Zombie, Chernoff faces, and the myriad quirks and blind spots that haunt the human mind. But Blindsight's last, shattering insight is not the end of the story -- along with crew/ship/"Firefall" notes, a blackly funny in-universe lecture on resurrecting sociopathic vampirism (PDF - prev.), and a rigorously-cited (and spoiler-laden) reference section, tomorrow will see the release of Dumbspeech State of Grace Echopraxia [website], the long-delayed "sidequel" depicting parallel events on Earth. Want more? Look inside for a guide to the rest of Watts' award-winning (and provocative) body of work. [more inside]

Surfing Superheroes to the Rescue

AJ Lindner, a 6-year-old fan of Spider Man and other superheroes, recently underwent surgery for brain cancer. Facing the start of chemotherapy, which requires him to keep out of the water, the avid young swimmer had one wish: he wanted to go surfing. But the waters off Long Island were too cold. After a plea for a child-sized wetsuit went out on Facebook, a “Justice League” of surfers went to work to fulfill the boy’s dream.

Control a cockroach from your smartphone? There's an app for that.

After a TED Talk demonstration and a successful Kickstarter, Backyard Brains plans to release a kit instructing kids to strap a miniature backpack to cockroaches and insert electrodes into its brain, allowing the cockroach to be controlled by a smartphone app. Some scientists are less than pleased with the ethics of the project.

Automation turns us from actors into observers

Nicholas Carr's latest article for The Atlantic posits that automation presents risks, specifically of losing skill and talent. "The lack of awareness and the degradation of know-how raise the odds that when something goes wrong, the operator will react ineptly. The assumption that the human will be the weakest link in the system becomes self-fulfilling."

New information from a very old brain

Some sites are calling this the oldest brain found. However, there have been other finds and at least one major site in Florida that holds older remains. The trick now is to extract DNA and information that can aid in medical advances.

Why Sleep Deprivation Can Destroy You

In a nutshell, this new study provides evidence that we need a certain amount of sleep every night, because the brain takes this time to rid itself of toxic metabolic byproducts, which would otherwise accumulate in the brain and impair brain function, destroy neurons — and potentially cause neurodegenerative disorders.

League of Denial: The NFL, Concussions and the Battle for Truth

The New York Times is reporting that pressure from the NFL led ESPN to pull out of an investigative project with FRONTLINE regarding head injuries in American Football. The two-part investigative report and book will reveal how the NFL, over a period of nearly two decades, sought to cover up and deny mounting evidence of the connection between football and brain damage. ESPN has a $15.2 Billion deal with the NFL. (Football concussions previously: 1, 2, and 3)

"a certain... moral flexibility would be the only way to describe it"

Our Inconsistent Ethical Instincts
We like to believe that the principled side of the equation is rooted in deep, reasoned conviction. But a growing wealth of research shows that those values often prove to be finicky, inconsistent intuitions, swayed by ethically irrelevant factors. What you say now you might disagree with in five minutes. And such wavering has implications for both public policy and our personal lives.

Deciphering the Tools of Nature’s Zombies

Deciphering the Tools of Nature’s Zombies: The ability of parasites to alter the behaviour of their hosts fascinates both scientists and non-scientists alike. One reason that this topic resonates with so many is that it touches on core philosophical issues such as the existence of free will. If the mind is merely a machine, then it can be controlled by any entity that understands the code and has access to the machinery. This special issue of The Journal of Experimental Biology highlights some of the best-understood examples of parasite-induced changes in host brain and behaviour, encompassing both invertebrate and vertebrate hosts and micro- and macro-parasites.

DOWNTIME for the BRAIN

"Having felt what it’s like to have all the backlog of experiences cleared out of my head, I’m intolerant of letting it build up a backlog again. It feels too good when it’s all clean and clear. Another way of talking about this is to say that the frantic, amped up feeling of too much seeking clears away. When we are seeking all the time, we are intaking new material constantly without ever actually dealing with it."

CO2 make dumb

Have you ever been in a room with lots of people and not great ventilation. Or even a room with normal ventilation. You may be cognitively impaired due to elevated levels of CO2 once considered safe now thought enough to make you a little dumb. 600ppm is now thought too much, but “there are plenty of buildings where you could easily see 2,500 ppm of CO2 — or close to it — even with ventilation designs that are fully compliant with current standards.. classrooms frequently exceed 1,000ppm."

Always wondered if Tom went on to work in banking.

John D. Fitzgerald had written three fictionalized memoirs of his family's life in the late 19th-century Utah west before the night he happened to regale a group of friends with childhood stories of his money-crazed brother, Tom. At their urging, he crafted a funny and clever series of children's books chronicling the adventures of The Great Brain. Like countless other readers, the blogger and researcher behind Finding Fitzgerald (and its companion blog and Facebook page) has been fascinated with discovering the real settings and stories behind the books. And the truly committed can even watch Jimmy Osmond in the 1978 film adaptation.
