The human tongue does more than just taste food. Of course, one needs the tongue for better pronunciation of words and effective communication. Surprisingly the tongue is also a valuable channel for communication with one’s brain. An electrolyte-rich saliva and a high density of sensory nerve receptors on the tongue enable this communication. With the nerve-endings of the tongue being superficial, this communication is completely non-invasive.
Albert Einstein, when asked to explain his theories in layman's terms, once famously said, "When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute and it's longer than any hour. That's relativity." That's also how our brains work to "tell time," according to research conducted by Sylvie Droit-Volet from Blaise Pascal University and Sandrine Gil from Poitiers University, France.
You may have perhaps heard of game-theory and behavioral economics, but like many within and outside the field the term neuroeconomics seems to be a revolutionary one. Neuroeconomics is, briefly put, an innovative research program, which combines findings and modeling tools from economics, psychology and neuroscience to account for human choice behavior.
The ability to communicate in multiple languages not only provides doorways to new cultural and social experiences but also apparently promotes brain growth and staves off the onset of dementia and Alzheimer’s disease. Researchers at the University of Kentucky and Kyungpook National University in South Korea studied 110 participants (who were either bilingual or monolingual) while undergoing functional magnetic resonance imaging (fMRI).
