STUDIES have shown that many of us are so preoccupied with future expectations, we fail to see what’s right in front of us.
A well known attention experiment at Harvard showed that many people missed seeing a 200-pound gorilla walking through a small group of basketball players.
Not so for a clinically blind man, who clearly saw what he should not have seen. A surprised science writer, Andrea Gawrylewski, reporting in The Scientist, described the experiment and wondered:
“How much can you see with a non-functioning visual cortex?”
“With lesions on both sides of his visual cortex,” reports a paper published in Current Biology, “he was able to flawlessly navigate an obstacle course.”
Biologists and neurologists are still searching for the hardware (neurons) responsible for this seeming impossibility.
