A husband's brain is sick, unable to see number 2 and 9

That sounds nice, but that's exactly what happened to a man who was suffering a rare form of neurodegenerative disease called coronary syndrome, and now he can detect issues 2 and 9.

This disease often leads to memory and movement problems but also to the inability to identify numbers.

In a new study published in the magazine PNAS, a team of scientists, has described how the unique inability sheds light on how the brain processes visual awareness.

The inability to identify numbers was an immediate puzzle for researchers. If the man in question could read letters and words but not numbers, it meant that he should identify ʹ numbers and then select them against them.

Inadequacy seems to be a particular type of metamorphopsis, a visual defect that makes linear objects appear curved or circular.

When he sees a number, his brain must be “hoh” which is the number before I see it is a true paradox,” said Michael McCloskey, senior researcher.

In this research, we found out what the processing was going on out of consciousness. ”

The man in question could not see the words or drawings placed in or near the number 2 and 9. For example, it was impossible to see the image of a drawn violin in number 3, but when the violin was drawn further from the number, he could see it.

Research had some interesting implications for conscience theories.

As it says, some theories propose that people are able to perform certain “ipe processes of complex cognitive” because our conscience interacts with deep-level processes in the brain.

But the results suggest the conscience could play less role, because the man in question “was making complex and sensitive reactions in the absence of conscience. ”
