myelination ?

Question

is it what connects the 2 halves of the brain? and the rate of myelination is most directly facilitated by genetics? or frontal cortex maturation?

Answer 1

no the two halves of the brain are connected by neuronal fibres which are myelinated and neuroglia in a formation called the corpus callosum.myelination itself is a function of age for as age advances, researches have proved that myelination occurs and the grey matter gets reduced. this happens in adoloscence and is held responsible for the 'risk taking' behaviour of the post-pubescents as radical changes take place in the brain as it get competely 'rewired' and 'insulated'. this process is said to commence at the occipital pole progressing eventually to the pre-frontal cortex which is responsible for the 'judgement' and 'maturity' which explains why it develops so late late. also this myelination process is completed faster in females as compared to males. that explains the conventional theory that girls mature faster than the boys. and a more pronounced wave of myelination suggests a higher intelligence which may have a genetic basis but don't get carried away for research has shown that the childhood schizophrenics show a very high rate of myelination and grey matter thinning.

Answer 2

Myelin doesn't connect the two halves of the brain. That's the corpus collosum.

Myelin is a fatty product that is produced by Schwann cells in the brain, or oligodendrocytes in the spinal cord and peripheral nervous system. This fat creates a sheath around nerve cells so that they can conduct electricity without shorting out - just like how a wire has insulation around it.
