Increase the basic cable activity of pallium cell, the inhibition that improves hemishere condition, restore to have stimulative effect to brain function.
Dr Brinkman, a brain researcher at the Australian National University in Canberra, has suggested that evolution of speech went with right-handed preference.
Lashley failed to find the engram—his experimental animals were still able to find their way through the maze, no matter where he put lesions on their brains.
But this may betray a certain psychological naivete, for a growing research base is showing much of our moral thinking is automatic and nonconscious - mindless even.
According to Brinkman, as the brain evolved, one side became specialised for fine control of movement (necessary for producing speech) and along with this evolution came righthand preference.
