The Neurology of Reading

Question: What is happening in the brain when we read?

Margaret Atwood: The neurology of reading is another thing that people are writing about and investigating a lot.  That is, what is happening in your brain when you read?  It turns out because I know a friend who had this kind of stroke that you can have a kind of stroke that makes it possible for you to write, you can still write, but you can’t read what you’ve just written.  So reading and writing you would think would be in the same little box in the brain, but they’re not.  

Anything that we do is built on a pre-existing brain platform or program which is then adapted for other uses.  So language is pretty old and it’s also built-in.  So children arrive in the world and then they pick up language just by being around other people who are talking.  Nobody sits down and teaches them.  

Reading, on the other hand, you will not pick up unless somebody spend some time with you, and writing is even – writing by hand is apparently even harder.  So what are the platforms that these things are built on, and it has been proposed that reading is built on very ancient program that had to do with reading animal tracks.  So what you’re doing is you’re looking for visual signs made by somebody else and you are interpreting those back into a story that originally, of course, allowed you to track the animal or to figure out if the animal was tracking you.  Equally important.  You were able to tell what was around in your vicinity by reading those tracks.  

So what are those marks we make?  What are those marks on a sheet of paper, piece of stone, clay tablet?  They’re like animal tracks in that we look at them; we translate them back into something which is language.  And that language can be put together in our brains to tell a story, create a poem, whatever the writing may have been.  

As for the writing, those are the tracks we make.  So that’s probably based on some sort of display or marking program.  And that too is pretty old.  And if you go back to cave paintings, those – the hand prints on the cave, drawings on the cave, the markings, the pieces of stone or bone that they’ve now found with rhythmic scratches on them.  They’re all forms of signaling, so it took awhile for that to become what we now know as alphabets or language systems, but it probably all had its origins in that form of marking.  And somebody has a theory that all of the alphabets are taken from natural – that they had their origins in natural signs, pictographs depicting natural things.

Reading may have evolved from early hunters’ skills of interpreting animal tracks, which allowed them to find food and determine whether they themselves were being hunted.

Self-driving cars to race for $1.5 million at Indianapolis Motor Speedway ​

So far, 30 student teams have entered the Indy Autonomous Challenge, scheduled for October 2021.

Indy Autonomous Challenge
Technology & Innovation
  • The Indy Autonomous Challenge will task student teams with developing self-driving software for race cars.
  • The competition requires cars to complete 20 laps within 25 minutes, meaning cars would need to average about 110 mph.
  • The organizers say they hope to advance the field of driverless cars and "inspire the next generation of STEM talent."

Mind & Brain
  • A study at Harvard's McLean Hospital claims that using the language of chemical imbalances worsens patient outcomes.
  • Though psychiatry has largely abandoned DSM categories, professor Joseph E Davis writes that the field continues to strive for a "brain-based diagnostic system."
  • Chemical explanations of mental health appear to benefit pharmaceutical companies far more than patients.

  • The company's protein powder, "Solein," is similar in form and taste to wheat flour.
  • Based on a concept developed by NASA, the product has wide potential as a carbon-neutral source of protein.
  • The man-made "meat" industry just got even more interesting.

Navy SEALs: How to build a warrior mindset

SEAL training is the ultimate test of both mental and physical strength.

Videos
  • The fact that U.S. Navy SEALs endure very rigorous training before entering the field is common knowledge, but just what happens at those facilities is less often discussed. In this video, former SEALs Brent Gleeson, David Goggins, and Eric Greitens (as well as authors Jesse Itzler and Jamie Wheal) talk about how the 18-month program is designed to build elite, disciplined operatives with immense mental toughness and resilience.
  • Wheal dives into the cutting-edge technology and science that the navy uses to prepare these individuals. Itzler shares his experience meeting and briefly living with Goggins (who was also an Army Ranger) and the things he learned about pushing past perceived limits.
  • Goggins dives into why you should leave your comfort zone, introduces the 40 percent rule, and explains why the biggest battle we all face is the one in our own minds. "Usually whatever's in front of you isn't as big as you make it out to be," says the SEAL turned motivational speaker. "We start to make these very small things enormous because we allow our minds to take control and go away from us. We have to regain control of our mind."
