Left-brained or Right-brained
#1
Hi,
Is anyone into documentaries? Just saw a really interesting one from Nat Geo, The Brilliant Brain. Which talks about talented, right-brain individuals who have amazing but obsessive gifts in painting, math, memory and really meticulous on details of what they see. Some are born with this gift, whereas others acquire in by accident(illness, hormones changes etc).

Another part of this documentary performs a experiment, to see if it is possible to manually trigger and improve the memory and visual senses of a person. The experiment requires a test subject to read lines from a computer screen, draw a horse and finally guess the number of dots at a glance on 20 instances. The individual has to perform the tasks one time before any simulation. And then again after a simulation(magnetic pulses) to temporary quiet down the left brain, so the the right brain takes over and thus becomes more active.

Amazingly, results shows that the test subject is able to perform the task better after the simulation.

Can vision be improve in the same manner, since 'seeing' is primary a right-brained function? It seems that Dr Bates' method (relaxation, palming, memory etc) indirectly improving the eyesight by improving the functions of the right-brain. Dr Bates' was way ahead of his time in this aspect, as it seems scientists are only just discovering manual ways to control behavior using left/right brain isolation techniques. But is really balancing the left/right brain inclination as easy as Dr Bates' implies?

Just some thoughts.

Petal

Vision is not a right brain function. Visual neural pathways are spread thoughout the brain both hemispheres, with neurons containing information from the visual field left of centre travelling primarily in the right brain and those from the visual field right of centre primarily in the left brain. The information from both fields is processed in occipital cortex which spreads over the rear of the brain and is both left and right of centre.

Drawing, reading, estimating numbers of dots etc are not solely visual functions. They involve motor actions, memory, spatial understanding, language, number awareness etc etc and some of those higher functions may be located more in one hemisphere than the other.

Judyb,
I can't question the science of what your saying. Sight being such a complex process uses many parts of the brain. I think when Petal refers to vision being right brained, she is addressing the portion of vision that we are exploring through Bates. If the term "right-brained" represents the creative/non analytical function of the mind then I know from experience that vision, as we are looking at it, is a "right-brained" endeavor, although we might not want to word it as such to avoid correction from left-brained scientists.

Thanks for the correction. Your information is quite insightful.
