A Walnut looks like a little brain, a left and right hemisphere, upper cerebrums and lower cerebellums. Even the wrinkles or folds on the nut are similar to those of the neo-cortex. Scientists claim that walnuts help in developing over three dozen neuron-transmitters within the brain enhancing the signaling &amp; encouraging new messaging link between the brain cells. Walnuts help ward off dementia. They may also extract &amp; break down the protein based plaques associated with Alzheimer’s.
