Arkhamhaus Images - Getting by with a little help...

"You show what we regard more as a competition phenomenon than impairment.

Sit down."

"Okay," Fred said stoically, sitting down.
"Competition," the other psychologist said,
"between the left and right hemispheres of your brain.
It's not so much a single signal, defective or contaminated;
it's more like two signals that interfere with each other by carrying conflicting information...
It's as if you have two fuel gauges on your car,
and one says full and the other registers empty.
They can't both be right. They conflict... Here's what I mean...
There should never be two gauges reporting conflicting information,
because as soon as that happens you have no knowledge of the condition being reported on at all.
This is not the same as a gauge and a backup gauge,
where the backup one cuts in when the regular one fouls up."
Fred said, "So what does this mean?"
"I'm sure you know already," the psychologist to the left said.
"You've been experiencing it, without knowing why or what it is."
"The two hemispheres of my brain are competing?" Fred said.
"Yes."

"Why?"
