Brain Story Exam Questions With
Solved Solutions
25 - ANSWER-Brain Development starts shortly after conception. The brain is
considered mature around the age of:
Early childhood, late childhood, adolescence, adulthood - ANSWER-Order these stages
of development from greatest plasticity to least
3 - 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 -
ANSWER-How do experiences shape the developing brain?
Sensory abilities, motor skills, emotional skills, executive function skills - 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 - ANSWER-At what stage of development do negative
experiences influence the architecture of the developing brain?
The interaction between genes and environmental influences - ANSWER-Most traits
and diseases in humans are derived from:
An environmental factor modifies the area surrounding a gene such that its expression
decreases - ANSWER-Which of the following is an example of an epigenetic effect?
, The glucocorticoid receptor gene - ANSWER-Which gene has been shown to be
epigenetically modified by the quality of maternal care in rat offspring?
The stress response increases - 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?
Childhood maltreatment - ANSWER-What pre-exisiting condition(s) are associated with
epigenetic modification of the glucocorticoid receptor gene in victims of suicide?
Manual dexterity - ANSWER-Which of the following outcomes is NOT related to the
quality of parental care a child receives?
Cortisol and adrenalin - ANSWER-Which two hormones are involved in initiating our
response to stress?
Tolerable stress is buffered by supportive adult relationships but toxic stress is not -
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 - 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 - ANSWER-Early life stress is associated with what physiological
change in adulthood?
Pre-frontal cortex, hippocampus, amygdala, hypothalamus, pituitary gland - ANSWER-
Which of these answers below correctly identifies the brain structures involved in
mediating our responses to stress?
