Does Football have a Future?
: Football players are anywhere from five to nineteen times more likely than a member of the general population to suffer from a dementia-like illness. This is likely a result of Chronic Traumatic Encephalopathy
), neurodegeneration caused by receiving multiple concussions or even subconcussions that are not detectable around time of impact. CTE has been linked to other mood and behavior changes, including suicidal depression (a great review of the medical literature generally),
and has been found in football players as young as 21
. And, of course, there is the sometimes debilitating physical disability (either acutely or later in life) from playing a hard-contact sport. The NFL has a long history of adjusting safety standards in bits and pieces (e.g., legalization of the forward pass
) to meet public concern over potential injury and disability from playing the sport, though still to some degree publicly denies a connection between football and brain damage
. New Yorker writer Ben McGrath
talks to football players (past and present), their families (often left behind by untimely death or dementia-twilight), franchise heads, and doctors to explore this history, the crushing legacy of sports injuries, and the question of whether it is possible to reform the rules to minimize the risk of concussion and thus the risk of CTE (if any such risk is acceptable). Would it still be football if such changes were to tone down the violence? (Yes, No [from iconoclast Buzz Bissinger]
) And, uncomfortably: is the sport of football unethical for its players, even if entered into on their own volition? (previously in the New Yorker
; previously on MetaFilter 1, 2, 3
) [more inside]

"Piloting London’s distinctive black cabs (taxis to everyone else) is no easy feat. To earn the privilege, drivers have to pass an intense intellectual ordeal, known charmingly as The Knowledge
. Ever since 1865, they’ve had to memorise the location of every street within six miles of Charing Cross – all 25,000 of the capital’s arteries, veins and capillaries. They also need to know the locations of 20,000 landmarks – museums, police stations, theatres, clubs, and more – and 320 routes that connect everything up." Acquiring The Knowledge changes the brains
of those who acquire it.

Are you tired of reading about how neuroscientists have discovered the area of the brain devoted to a single, oddly-specific function, but lack access to the sophisticated neuroimaging technologies needed to refute them? NeuroSynth
has you covered. [more inside]

modern and contemporary philosophical tradition, which has emphasized the specialness and security of self-knowledge, especially self-knowledge of the stream of conscious experience, and in comparison the relative insecurity or derivativeness of our knowledge of the physical world around us, has the epistemic situation upside-down

The Brain on Trial.
Advances in brain science are calling into question the volition behind many criminal acts. A leading neuroscientist describes how the foundations of our criminal-justice system are beginning to crumble, and proposes a new way forward for law and order.
"We may someday find that many types of bad behavior have a basic biological explanation—as has happened with schizophrenia, epilepsy, depression, and mania." [more inside]

More evidence of brain plasticity:
Some blind people are able to use echolocation to perceive space and objects around them in surprising detail, even though the time differences in echoes necessary to do this are two small to be consciously perceived. An fMRI study by Lore Thaler, Stephen Arnott and Melvyn Goodale revealed that people who are especially adept at this use their calcarine cortex (a.k.a. V1 or primary visual cortex) to process spatial information from the echoes.
The original paper. A shorter discussion.

The International Science & Engineering Visualization Challenge 2010
- "Researchers are generating mind-boggling volumes of data at exponentially increasing rates. The ability to process that information and display it in ways that enhance understanding is an increasingly important aspect of the way scientists communicate with each other and—especially—with students and the general public. That's why, for the past 8 years, Science and the U.S. National Science Foundation (NSF) have co-sponsored annual challenges to promote cutting-edge efforts to visualize scientific data, principles, and ideas. This year's awardees
span scales from nanoparticles to colliding galaxies, and from microseconds to millennia."

Swimming around in a mixture of language and matter, humans occupy a particular evolutionary niche mediated by something we call 'consciousness'. To Professor Nicholas Humphrey we're made up of "soul dust
": "a kind of theatre... an entertainment which we put on for ourselves inside our own heads." But just as that theatre is directed by the relationship between language and matter, it is also undermined by it
. It all depends how you think it.

"This is a subject of but small importance; and I know not whether it will interest any readers, but it has interested me."
Quick... what was Darwin's most popular book? If you answered The Origin of Species, you were wrong. It was his last book, published the year before he died, The Formation of Vegetable Mould Through the Action of Worms With Observation of Their Habits
[first presented 1 Nov. 1837
, as noted in the record of the Royal Geological Society]). Darwin noted when he was beginning his career that worms churned up soil, causing heavier objects to sink slowly in the soil. He noted that all soil had passed through the alimentary duct of worms. It started off a fashion of cultivating worms by gardeners that continues to the present day.
-We recently learned that we owe an element of our unique cerebral cortex, or pallium to our marine worm ancestors.
(In amphibians, the cerebrum includes archipallium, paleopallium and some of the basal nuclei. Reptiles first developed a neopallium, which continued to develop in the brains of more recent species to become the neocortex of mammals." [&, ultimately, you and you and we]) [more inside]

An idle brain may be the self's workshop.
'Recent research suggests that mind-wandering may be important and that knowledge of how it works might help treat such conditions as Alzheimer's disease, autism, depression and schizophrenia.' Once upon a time, scientists didn't regard idle musings of the wandering mind as very important. 'But in the span of a few short years, they have instead come to view mental leisure as important, purposeful work — work that relies on a powerful and far-flung network of brain cells firing in unison. Neuroscientists call it the "default mode network."''Understanding that setting may do more than lend respectability to the universal practice of zoning out: It may one day help diagnose and treat psychiatric conditions as diverse as Alzheimer's
— all of which disrupt operations in the default mode network. Beyond that lies an even loftier promise. As neuroscientists study the idle brain, some believe they are exploring a central mystery in human psychology: where and how our concept of "self" is created, maintained, altered and renewed.'

YOUR BRAIN ON COMPUTERS
“Almost certainly, downtime lets the brain go over experiences it’s had, solidify them and turn them into permanent long-term memories,” said Loren Frank, assistant professor in the department of physiology at the university, where he specializes in learning and memory. He said he believed that when the brain was constantly stimulated, “you prevent this learning process.”

. Banned from advertising in F1 racing, a major tobacco company that sponsors a team came up with a novel design solution
that may play on this visual effect to an opposite, suggestive effect, depending on the observer. European officials were not amused
, going so far as to call the design "subliminal". Ferrari responded by removing
traces of the design from its cars. Judas Priest
