The frontal lobe is the last part of the brain to develop fully.
Astrocytomas can develop on any part of the brain or spinal cord
Hippocampus
The association areas are the last regions of the brain to fully develop their myelination, which helps with faster and more efficient neural communication. These areas are responsible for higher cognitive functions like reasoning, problem-solving, and decision-making in the brain.
forebrain
The prefrontal cortex, which is involved in higher-order thinking, decision-making, and social behavior, is one of the last areas to develop in association areas of the brain. This process typically continues into early adulthood.
The cerebrum develops from the telencephalon, which is one of the five vesicles of the embryonic brain. It is the largest part of the brain and is responsible for higher brain functions such as thinking, memory, and voluntary movements.
the frontal lobe
The cerebral cortex, the grey, folded, outermost layer of the cerebrum that is responsible for higher brain processes such as sensation, voluntary muscle movement, thought, reasoning, and memory.
By being positive you can develop your brain,
That does occur to some extent, but areas of the brain are highly specialized and also affect opposite sides of the body. The place in the brain where the crossover occurs from left to right side is in the brain stem in a part called the medulla oblongata. This part of the archeocortex, the oldest and most primitive portion of our brains and rewiring this part of the brain is not possible.
the effects are they cannot speak or do anything. If they were not talked to as babies or toddlers the part of your brain that does speech doesn't develop
