Brain Story UPDATED ACTUAL Exam
Questions and CORRECT Answers
25 - CORRECT ANSWER - Brain Development starts shortly after conception. The brain is
considered mature around the age of:
Early childhood, late childhood, adolescence, adulthood - CORRECT ANSWER - Order these
stages of development from greatest plasticity to least
3 - CORRECT ANSWER - The age at which a human brain has the most connections
between neurons is:
They influence which neural connections are strengthened and which are pruned away -
CORRECT ANSWER - How do experiences shape the developing brain?
Sensory abilities, motor skills, emotional skills, executive function skills - CORRECT
ANSWER - Different abilities, and their underlying neural circuits, develop in a bottom-up
sequence during sensitive periods. Put the following abilities in the correct sequence of
development.
At any stage of development - CORRECT ANSWER - At what stage of development do
negative experiences influence the architecture of the developing brain?
The interaction between genes and environmental influences - CORRECT ANSWER - Most
traits and diseases in humans are derived from:
An environmental factor modifies the area surrounding a gene such that its expression decreases
- CORRECT ANSWER - Which of the following is an example of an epigenetic effect?
The glucocorticoid receptor gene - CORRECT ANSWER - Which gene has been shown to be
epigenetically modified by the quality of maternal care in rat offspring?
, The stress response increases - CORRECT ANSWER - What happens to the stress response
system when the glucocorticoid receptor gene is epigenetically modified such that it is less active
and produces fewer receptors?

ANSWER - Which of the following answers best describes the difference between tolerable
and toxic stress in a child?
Silencing of the glucocorticoid receptor gene and glucocorticoid resistance - CORRECT
ANSWER - Allostatic changes due to activation of the stress response can produce allostatic
load on the body and brain. Which of the following pairs does NOT correctly identify an
allostatic change and its corresponding allostatic load?
All of the above - CORRECT ANSWER - Early life stress is associated with what
physiological change in adulthood?
