BRAIN STORY CERTIFICATION 64 2026 FINAL
PAPER COMPLETE QUESTIONS AND ANSWERS
FULL SOLUTION
◉ 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
◉ what pre-existing conditions are associated with epigenetic
modification of the glucocorticoid receptor gene in victims of
suicide.
Answer: childhood maltreatment
◉ which aspect of development is NOT affected by social
interactions.
Answer: cognitive, social, emotional, language, physical and
