New scientific research suggests that blood not only delivers oxygen and other supplies to our brain but is actually involved in neuronal activity. According to MIT neuroscientist Christopher Moore, the localized flow of blood can actually affect individual neurons that relay signals in our brains. Someday, his theory, called the Hemo-Neural Hypothesis, could possibly lead to better treatments for diseases like Alzheimer's, schizophrenia, and epilepsy. From the McGovern Institute for Brain Research:
How could blood flow affect brain activity? Blood contains diffusible factors that could leak out of vessels to affect neural activity, and changes to blood volume could affect the concentration of these factors. Also, neurons and support cells called glia may react to the mechanical forces of blood vessels expanding and contracting. In addition, blood influences the temperature of brain tissue, which affects neural activity.
To Moore's knowledge, the Hemo-Neural Hypothesis offers an entirely new way of looking at the brain. "No one ever includes blood flow in models of information processing in the brain," he said. One historical exception is the philosopher Aristotle, who thought the circulatory system was responsible for thoughts and emotions. Perhaps the ancient Greeks were on to something.
Alex Wood is an addict but won’t give up his smartphone. But he has five strategies for limiting its control over him: “I used to wake up tired. My body would ache and my head felt sore, like waking up with a hangover. Finally, I took control, like attending an AA class for addicts, I […]
We just got the Sport model of the EPIKGO hoverboard at my office. Besides being terribly chic, it’s apparently bulletproof.
Ok, it’s not just solar powered. It’s also an anti-theft, waterproof marvel that keeps my phone’s power bar from ever getting into the red.Sure the idea seems obvious now – tuck a gigantic solar powered battery pack into an exposed slot and turn the wearer into a walking energy harvester. Simple maybe, but I didn’t […]
All the filters in the world won’t save your smartphone pics from a shaky hand. To really step up your mobile photography game, you’ll need some kind of mount to hold it steady. You could buy a smartphone attachment for a conventional camera tripod, but who wants to carry that kind of gear everywhere they […]
The forced transition from analog to digital TV signals was probably met with relative indifference from people with Netflix subscriptions and the “I don’t even own a TV” snoots. But anyone living in the vast swaths of the country that don’t have guaranteed high-speed internet, broadcast TV is a perfectly valid (and 100% free) way […]
When Apple revealed the new MacBook in 2016, one of the biggest issues raised with the notebook’s new design (aside from ire over the slew of new adapters you’d inevitably have to buy) was the removal of one of its most beloved proprietary features, the magnetic charging cable. Thankfully, third-party peripheral makers have taken up […]
