Stimulation to the Brain and its Affects
Do the levels of stimulation an individual receives as a child matter? Mark R. Rosenzweig, Edward L. Bennett, and Marian C. Diamond believe that it does. According to them, an adequate amount of stimulation can actually raise the ability to learn and increase the size of certain parts of the brain that are used in the learning process.
In 1785, studies by an Italian, anatomist named Malacarne found more complicated folds and fissures in animals who had received extensive training, than with those who had not. Malacarne would train a group of animals (the variable) and not train another group (the control group), then dissect the animals; brains to see which were more complex. This study by Malacarne was dropped however for unknown reasons.
Rosenzweig, Bennett, and Diamond performed an experiment similar to Malacarne;s in order to test the theory that the more stimuli a brain received the more complex it would become. They used groups of rats with one group not receiving any stimuli, while another group was introduced to new stimuli every day. During a four to ten week period, the rats were dissected and their brains examined. Rosenzweig, Bennett, and Diamond found that the cerebral cortex of the stimulated rats was thicker and heavier than the cortex of the non-stimulated rats.
The findings were important in that the cerebral cortex is the part of the brain that controls movement, learning, and memory. It is also important in that it controls the senses of vision, sight, smell, taste, and touch. The enlarged cortex demonstrates that the stimulated rats had a higher level of brain activity. These findings would seem to support their theory of stimulation to the brain.
My experience with cases of stimulation to the brain would also tend to support that theory. I have been around young children a lot since my best friend;s mother is a baby-sitter and I have noticed a di…
