Understanding the “It” in “Use It or Lose It”

From Macro to Micro: A Visual Guide to the Brain (IEEE Spectrum)

In the human brain, higher-level information processing occurs in the neocortex, neural tissue that forms the outer layer of the cerebral cortex. In its intricate folds, brain cells work together to interpret sensory information and to form thoughts and plans. The neocortex is divided into regions that take the lead on different types of processing. However, much of today’s neuroscience research focuses on mapping the connectome: the neural connections between regions…Keep Reading Article.

Forget thinking vs. feeling dichotomy. Think/ feel holistic brain functioning

“You often hear the word “calculating” used to describe someone who always seems to act deliberately, guided by reason rather than emotion. The idea behind this characterization is that human nature straddles a deep divide between thinking and feeling, but current research suggests otherwise. Brain-imaging studies, in particular, reveal an overlap between the sites in the brain that make it possible for us to perform mental arithmetic and those that enable us to regulate our emotions. In fact, these two dissimilar-seeming functions are housed in the same neighborhood of the cerebral cortex. But they don’t just reside near each other—they actually work together. “It’s possible that training the brain with mental math strengthens the capacity for emotional reappraisal, or perhaps continually running the process of emotional reappraisal increases the ability for mental calculations of other kinds like mental arithmetic.”

A new era of brain cartography, powered by neuroimaging and machine learning



Human brain mapped in unprecedented detail (Nature):

“Think of a spinning globe and the patchwork of countries it depicts: such maps help us to understand where we are, and that nations differ from one another. Now, neuroscientists have charted an equivalent map of the brain’s outermost layer — the cerebral cortex — subdividing each hemisphere’s mountain- and valley-like folds into Read the rest of this entry »

#13. Brain teaser to exercise your cognitive skills: Where do words go?

Temporal lobe Frontal LobeWords are stored in the tem­po­ral lobe of your brain (in green on the cerebral cortex image  to the left). But on which brain hemisphere, right or left? As you know, your brain has two sides (two hemi­spheres) con­nected by the cor­pus cal­lo­sum. You have one tem­po­ral lobe on each side of the brain.

Master a new language and grow hippocampus and cerebral cortex

Learning New Languages Helps The Brain Grow (Medical News):

“The learning of languages allows the brain to stay “in shape”, by causing certain parts of the brain to grow, including the hippocampus and three areas of the cerebral cortex…This finding came from scientists at Lund University, after examining young recruits with a talent for acquiring languages who were able to speak in Arabic, Russian, or Dari fluently after just 13 months of learning, before which they had no knowledge of the languages Read the rest of this entry »
