An Evaluation of the Left-Brain vs. Right-Brain Hypothesis with Resting State Functional Connectivity Magnetic Resonance Imaging

There is a lot of statistics thrown in here, but the only significant one I can find is this. The right brain is not a copy of the left brain. Beyond this it's a bunch of fillers. Now if we look at the raw data, there is the delight in this study. Pay close attention to figure 1. http://www.plosone.org/ar...

Note the differences between the top row, middle row and bottom row, the focus your eyes on the 2nd row, middle image. Do you see it? There! Look at the red first. Study it. Then look at the blue. What do you see? I see the answer.

The right brain is signaling the left, at the same time the left is answering the right. They are not working together as these researchers report, they are talking to each other. It's amazing. Notice the rhythm. Granted there are limited images to relate to, but the pattern is there and it's distinct. R, L, R, R, L, L, R, R, L.

My hypothesis from this raw data is this. The right brain is capable of answering the left. The left is awaiting a SINGLE signal from the right, and IF the right is listening to that exact signal, then the left can reply back.

My thoughts. There is a strong and unique association between the right and the left brain that must be acknowledged by the left. If it is missed by the left then the signal is dropped by both the right and the left, and the connection is lost. We call this being absent minded. Later if a similar signal is again sent from the right, and this time the left brain picks it up then what was thought of as absent minded result in knowing, but in reality they are different signals.

Example: Martha forgot where she put her keys. She tries to remember. Her left brain sends a signal to her right. Hey right. Where are my keys? Her right brain is busy trying to gather her bag, check her makeup and so on, and it drops the signal. After she is done with everything else and now her focus is just on finding her keys, her left brain again sends a signal to the right and this time it's picked up and she easily finds her keys IF that knowledge is there.
