Illustrate the structure of brain

Brain is capable of changing its structure in numerous ways. Synapses become stronger and denser. Tiny blood vessels increase in size and number to bring more blood flow to brain. Myelin, the fatty sheath which wraps around nerve connections, thickens, helping enhance flow of nerve signals. New nerve cells are even born in specific brain areas and with the right environmental influences, new cells migrate, differentiate and form synapses with other cells, a process called as "neurogenesis." Scientists have linked neurogenesis to learning and have demonstrated that stimulating environments increase the rate of neurogenesis. Together, these findings paint a picture of a dynamic, adaptable brain which is ever changing, ever responding to our surroundings and our experiences.
