Brain Story Certification Exam 2026
Questions and Answers
the brain begins as an embryonic structure called the - Answer -neural tube, shortly
after conception it is formed in neurulation, all areas of the brain develop from here
the brain is considered mature around what age - 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
what is the sequence in which we learn our abilities - Answer -sensory, motor,
emotional skills, executive function skills (begin in early childhood but their
sensitive period of development continues into early adulthood)
what stages of development are the most plastic and the least - Answer -early
childhood, late childhood, adolescence, adulthood, the brain becomes
progressively less plastic with age
the age at which a human has the most connections between neurons is - Answer -
3, as the brain ages, unused connections are pruned away and active connections
are strengthened

, how do experiences shape the developing brain - Answer -they influence which
neural connections are strengthened or pruned, they help us practice our skills
at what stage of development do negative experiences influence the architecture of
the developing brain - Answer -at any stage of development, which neural circuits
will be affected depends on when the negative experience occurs
most traits and diseases in humans are derived from - Answer -the interaction
between genes and environmental influences
what is an example of an epigenetic effect - Answer -an environmental factor
modifies the area surrounding a gene such that expression decreases
is manual dexterity related to the quality of parental care a child receives - Answer
-no
which gene has been shown to be epigenetically modified by the quality of
maternal care in rat offsrping - Answer -the glucocorticoid receptor gene which is
methylated in response to maternal care
what happens to the tress response system when the glucocorticoid receptor gene is
epigenetically modified such that it is less active and produced fewer receptors -
Answer -the stress response increases
