Recently I came across these pics on a BBC Science & Environment page:
"The brain's wiring diagram is not [...] fixed. It is thought that changes occur after each experience, and so each person's brain map is different - an ever changing record of who we are and what we have done."
This echoes the words of Daniel Tammet cited in an earlier post:
"Every thought, every daydream, every emotion alters the brain's fantastically intricate structure in subtle but definite ways."
"Our minds are miracles - immensely intricate webs of gossamer light inside our heads that shape our very sense of self and our understanding of the world around us. Moment by moment throughout our lifetime, our brains hum with the work of making meaning: weaving together many thousands of threads of information into all manner of thoughts, feelings, memories, and ideas."
