The Brain's Angular Gyrus May Be Key To Metaphor Comprehension

Or it may not. But it kinda seems like it.

(I love this stuff. The sooner we figure out how the brain works, the sooner we can go about creating a computer to house our consciousness, the sooner we can get on with the singularity already.)
(Never mind that it'll never work :-)

Brain Region Linked to Metaphor Comprehension


Vilayanur S. Ramachandran of the University of California at San Diego and his colleagues tested four patients who had experienced damage to the left angular gyrus region of their brains...

The angular gyrus is more developed in humans than in other primates and is located in the brain at the junction of areas specialized for processing touch, hearing and vision. "While it would be premature to conclude that the angular gyrus is the 'metaphor center' of the human brain," Ramachandran says, "we suggest that the evolution of the dominant angular gyrus contributed enormously to the evolution of many quintessentially human abilities, including metaphorical--and other abstract--thinking." He will present the results on Friday at the annual meeting of the American Psychological Society in Los Angeles.

Brain Region Linked to Metaphor Comprehension

Metaphors make for colorful sayings, but can be confusing when taken literally. A study of people who are unable to make sense of figures of speech has helped scientists identify a brain region they believe plays a key role in grasping metaphors.

Vilayanur S. Ramachandran of the University of California at San Diego and his colleagues tested four patients who had experienced damage to the left angular gyrus region of their brains. All of the volunteers were fluent in English and otherwise intelligent, mentally lucid and able to engage in normal conversations. But when the researchers presented them with common proverbs and metaphors such as "the grass is always greener on the other side" and "reaching for the stars," the subjects interpreted the sayings literally almost all of the time. After being pressed by the interviewers to provide deeper meaning, "the patients often came up with elaborate, even ingenious interpretations, that were completely off the mark," Ramachandran remarks. For example, patient SJ expounded on "all that glitters is not gold" by noting that you should be careful when buying jewelry because the sellers could rob you of your money.

The angular gyrus is more developed in humans than in other primates and is located in the brain at the junction of areas specialized for processing touch, hearing and vision. "While it would be premature to conclude that the angular gyrus is the 'metaphor center' of the human brain," Ramachandran says, "we suggest that the evolution of the dominant angular gyrus contributed enormously to the evolution of many quintessentially human abilities, including metaphorical--and other abstract--thinking." He will present the results on Friday at the annual meeting of the American Psychological Society in Los Angeles. --Sarah Graham

Outsmarting "The Man" Feels Better Than Making Money From Ratting On Your Partners

A study conducted by Emory University's Department of Psychiatry and Behavioral Sciences suggests that we may be "hard-wired" to cooperate with each other -- in the sense that we get a shot of seratonin satisfaction upon working with an accomplice to keep your respective mouths shut during an infamous episode of the "prisoners dilemma."

I never understood what the big dilemma was. It seems easy enough to remember to not squeal on your partner and you both can only do better in the long run.

Mind Mapping For The Masses

The BBC has a great story on how the visual memory technique of mind mapping is now being used as a treatment for dyslexics.
(wow I had to cut and paste that "dyslexics" word to get it right :-)
