Boys with good motor skills are better problem-solvers than their less skillful peers, a study shows. In contrast to previous studies, the researchers found no association between aerobic fitness or overweight and obesity with cognitive function in boys. (1)
Go stand in front of a mirror. Hold
still, and look around, moving only your eyes. Look left, right, up, down. Look
at one eye, then the other. Their reflection is right there in front of you,
but no matter how hard you try, you’ll never see your eyes move. That’s because
when your eyes are in motion, you briefly go blind — and you can’t even tell.
This phenomenon is called “saccadic masking”.
Motion and human vision don’t mix so
well. Objects in motion — like trains or the legs of racehorses — look like
blurs. When you’re moving quickly, the world around you starts to blur, too. So
theoretically, the world around you should blur every time your eyes move.
Practically, however, this would be a mess. You’d be dizzy and motion sick all
So the human brain has evolved to
prevent constant blurring. The brain shuts off visual processing while the eyes
are in motion and restarts it once they’re still again. In the
“saccade,” the brief window of eye motion — which each last about 50
milliseconds — we can miss even major visual events, like a flash of light. And
though less than a second of blindness doesn’t sound so serious, keep in mind
that these tiny bursts of blindness happen thousands of times a day.
Cumulatively, saccadic masking means we’re blind for about 40 minutes a day. (1)
We humans walk with our feet. This is true, but not entirely. Walking, as part of locomotion, is a coordinated whole-body movement that involves both the arms and legs. Researchers at the Biozentrum of the University of Basel and the Friedrich Miescher Institute for Biomedical Research have identified different subpopulations of neurons in the spinal cord with long projections. Published in Neuron, the results show that these neurons coordinate movement of arms and legs and ensure a stable body posture during locomotion. (1)
Every move we make is a composite one.
We do not walk just with our feet.
We use our hands, mind, ears, eyes as well…
The same applies for everything else.
Everything is composed of many parts – what part we choose to acknowledge is exactly that: a matter of choice. The act of writing involves thinking, knowing, seeing, moving. The act of speaking involves moving the mouth as well as the hands, the mind, the eyes. The act of living involves dying. Oups! No, I do not want that.
It started as a headache, but soon became much stranger. Simon Baker entered the bathroom to see if a warm shower could ease his pain. “I looked up at the shower head, and it was as if the water droplets had stopped in mid-air”, he says. “They came into hard focus rapidly, over the course of a few seconds”. Where you’d normally perceive the streams as more of a blur of movement, he could see each one hanging in front of him, distorted by the pressure of the air rushing past. The effect, he recalls, was very similar to the way the bullets travelled in the Matrix movies. “It was like a high-speed film, slowed down.”
The next day, Baker went to hospital, where doctors found that he had suffered an aneurysm. The experience was soon overshadowed by the more immediate threat to his health, but in a follow-up appointment, he happened to mention what happened to his neurologist, Fred Ovsiew at Northwestern University in Chicago, who was struck by the vivid descriptions. “He was a very bright guy, and very eloquent” says Ovsiew, who recently wrote about Baker in the journal NeuroCase. (Baker’s identity was anonymised, which is typical for such studies, so this is not his real name).
It’s easy to assume that time flows at the same rate for everybody, but experiences like Baker’s show that our continuous stream of consciousness is a fragile illusion, stitched together by the brain’s clever editing. By studying what happens during such extreme events, researchers are revealing how and why the brain plays these temporal tricks – and in some circumstances, they suggest, all of us can experience time warping.
Although Baker is perhaps the most dramatic case, a smattering of strikingly similar accounts can be found, intermittently, in medical literature. There are reports of time speeding up – so called “zeitraffer” phenomenon – and also more fragmentary experiences called “akinetopsia”, in which motion momentarily stops. (1)
Time is something we believe it flows.
But some others times time stops to a halt.
When can we trust our senses?
When do we WANT to trust our senses?
Think of a world with no time.
And you will have it.
How can things Be if they change?
How can the cosmos Be in time?
How can anything exist in time?
It may sound weird, but the main proypothesis for the existence of anything is that time does not exist…
And there is only a handful of us who can actually feel that Reality.
