How do blind people solve math problems?
Q. People born without sight use which part of the brain to engage in numerical reasoning?- Published on 21 Sep 16a. Frontal
b. Temporal
c. Visual
d. Cerebral
ANSWER: Visual
For the first time, researchers have found that people born without sight solve math problems using visual areas of the brain.
- Humans and animals have a basic number sense that many believe evolves from seeing the world and trying to quantify all the sights
- Neuroscientists have found that the brain network behind numerical reasoning is identical in blind and sighted people
- Researchers found visual cortex in blind people is highly involved in doing math, indicating that the human brain is more adaptable than previously thought
- Blind people may not see anything in their lives, but they have the same number network as people who can see
- Researchers also found the more complicated the math problem, the greater the activity in the visual cortex
- New finding contradicts recent research
- The visual cortex is now found to respond to everything from spoken language to mathematics problems
