Question : the brain begins as an embryonic structure called
the
Correct answer: neural tube, shortly after conception it is
formed in neurulation, all areas of the brain develop from here
Question : the brain is considered mature around what age
Correct answer: 25, the brain is not mature until our mid-
twenties because the prefrontal cortex (which enables executive function abilities) continues to develop until this time
Question : what is the sequence in which we learn our
abilities
Correct answer: sensory, motor, emotional skills, executive
function skills (begin in early childhood but their sensitive period of development continues into early adulthood)
Question : what stages of development are the most plastic
and the least
Correct answer: early childhood, late childhood, adolescence,
adulthood, the brain becomes progressively less plastic with age
Question : the age at which a human has the most connections
between neurons is
Correct answer: 3, as the brain ages, unused connections are
pruned away and active connections are strengthened
Question : how do experiences shape the developing brain
Correct answer: they influence which neural connections are
strengthened or pruned, they help us practice our skills
Question : at what stage of development do negative
experiences influence the architecture of the developing brain
Correct answer: at any stage of development, which neural
circuits will be affected depends on when the negative experience occurs
