age is directly related to how many dendrites and axon form. The more a child does something (talks, for instance), the more mylinated, or cemented, the pathways in the brain get. When a pathway is mylinated, the easier it is to access that part of the brain and further expand the connections into that part. A six year old has seven times as many connections formed in their brain as compared to an adult. This is taking into consideration that a six year olds brain is only two thirds the size of an adults.When a human reaches the age of 10 or so, an enzyme is released into the brain, which dissolves any dendrite connections that are not mylinated very well. It seems that almost eighty percent of all connections that are formed prior are lost at this stage in development. So the term use it or lose is could be extremely appropriate in this case.A child who has been brought up watching TV all of the time while neurons are trying to make connections is going to have some serious problems. When the brain is taking in everything that it can get is senses on and all that a child is doing is watching television, there is going to be some serious damage. The telie is only working two senses, visual and auditory, and both not develop right because of a televisions physical setup.A speaker on the television has an extremely limited range that it can duplicate. So, when a child is growing up and the brain is expecting to be experiencing the sounds of the real world and all that it is getting is a 50hz (fidelity of a clock radio) range of sound coming from a box in the living room, full development of that part of the brain will not occur. Also, background music and sound effects in shows trick the mind and will have it expecting those types of things in regular situations, making socializing somewhat difficult without the things that kids are used to. Constantly updating is what a television screen does. A cathode ray shoots across a phosphorus pai...
