Shifting to light

The first verse of the beautiful and evocative I Fellowed Sleep by Welsh poet Dylan Thomas: I fellowed sleep who kissed me in the brain, Let fall the tear of time; the sleeper‚Äôs eye, Shifting to light, turned on me like a moon. So, planing-heeled, I flew along my man And dropped on dreaming and […]

Sport psychology

The 76 page publication includes features on aggression in sport (p.35); depression in sport (p.41), including comment on double Olympic gold medallist Dame Kelly Holmes’ admission earlier this year that she deliberately cut […]

Non-invasive neuroprosthetics

Nature reports that by simply recording the brain’s electrical signals from electrodes on the scalp, researchers have enabled trained participants to reliably control computer equipment, a feat normally associated with physical implants in the brain. This is part of the growing science of neuroprosthetics, that aims to create technology that directly interfaces with the brain. […]

Getting to grips with grasping

Reach and grasp a willing colleague by the arm, now let them go, and pick up a pen or pencil instead. The first movement requires a power grip, flexing all the fingers together towards the palm, the second movement uses a precision grip involving the thumb and forefinger. Easy to do? Apparently yes, but the […]

Scott Adams and focal dystonia

It, and his response to it, are discussed in an article in the Washington Post. Focal dystonia, which can affect the hand (where it’s commonly called “writer’s cramp” when it affects […]

Tyrannosaurus reflex

Waving, not designing

I got a wave messaging power-up cover for my Nokia 3220 phone. It’s got a line of LEDs along the back of the phone, and when you wave it, you can spell out messages in the air. Check this out: (That’s me, by the way. I posted more about this to my other weblog, if […]

Sinister Research

A couple of interesting bits of research on handedness in the news today. Chimps brains are asymmetrical in similar ways to human brains, and this is reflected in whether they’re left or right handed too. Why we have a preferred hand is still being debated, but this research shows handedness isn’t a consequence of the […]
