4.5 Frontal cortex and development of morals
The temporal cortex is related to the development of language and the occipital lobe is related to the development of eyesight. What is the frontal cortex related to? It is the development of morals. The frontal cortex is fully developed around 18 years old. The degree of maturity of a brain is measured by the myelination of neural paths. The axon of the long path is covered by white lipid tissues.
The tissues increase speed of the neural signal along the path, therefore, the transmission between each area of the brain is swift. The frontal cortex coordinates with other various areas of the brain and the long-distance transmission is very important. At 18 years old, the path to connect the remote brain areas to the frontal cortex has completely myelinated, and the frontal cortex can play various roles perfectly.
The story teller is a white lady. She got pregnant at 18 years old and married, then had a baby with Max. His father was a representative of the United Party, therefore, his family observed conventions to save face. But Max gave a toast to his sister Queenie and her husband Alan because he was married and had a wife and baby and became an adult.
