Why Do Our Brains Sometimes Fail?
Have you ever made a mistake while trying to execute the most rudimentary of tasks? Scientists have begun to understand why the brain sometimes loses its concentration for no good reason.
What's the Latest Development?
When researchers in Norway examined the brain activity of people doing repetitive tasks, they found that momentary lapses of concentration begin in the body's physiology some 30 seconds before a person actually loses concentration. "So what's causing the brain to wig out? As far as the researchers could tell, the test subjects' brains weren't getting tired, and they certainly weren't falling asleep. 'Autopilot would be a better metaphor,' explains Dr. Stefan Debener, who collaborated on the study."
What's the Big Idea?
Because there are physiological indicators of an approaching loss of concentration, scientists hope technology can be used to keep people from losing focus, especially in crucial fields such air traffic control. "Imagine, for example, a feedback device that could warn air traffic controllers when their attention waned too close a dangerously low threshold, or help keep you alert on the highway. With such a device in every human's pocket, brain farts could one day become a thing of the past."
While short-term results are positive, there is mounting evidence against staying in ketosis for too long.
- Recent studies showed volunteers lost equal or more weight on high-carb, calorie-restricted diets than low-carb, calorie restricted diets.
- There might be positive benefits to short-term usage of a ketogenic diet.
- One dietician warns that the ketogenic diet could put diabetics at risk for diabetic ketoacidosis.
Research shows that the way math is taught in schools and how its conceptualized as a subject is severely impairing American student's ability to learn and understand the material.
- Americans continually score either in the mid- or bottom-tier when it comes to math and science compared to their international peers.
- Students have a fundamental misunderstanding of what math is and what it can do. By viewing it as a language, students and teachers can begin to conceptualize it in easier and more practical ways.
- A lot of mistakes come from worrying too much about rote memorization and speedy problem-solving and from students missing large gaps in a subject that is reliant on learning concepts sequentially.
The surprisingly simple treatment could prove promising for doctors and patients seeking to treat depression without medication.
- A new report shows how cold-water swimming was an effective treatment for a 24-year-old mother.
- The treatment is based on cross-adaptation, a phenomenon where individuals become less sensitive to a stimulus after being exposed to another.
- Getting used to the shock of cold-water swimming could blunt your body's sensitivity to other stressors.
