BRAIN STORY EXAM 2025
QUESTIONS AND ANSWERS
, Brain Development starts shortly after conception. The brain is considered mature
around the age of: - CORRECT ANSWERS-25
Order these stages of development from greatest plasticity to least - CORRECT
ANSWERS-Early childhood, late childhood, adolescence, adulthood
The age at which a human brain has the most connections between neurons is: -
CORRECT ANSWERS-3
How do experiences shape the developing brain? - CORRECT ANSWERS-They
influence which neural connections are strengthened and which are pruned away

during sensitive periods. Put the following abilities in the correct sequence of
development. - CORRECT ANSWERS-Sensory abilities, motor skills, emotional skills,
executive function skills
At what stage of development do negative experiences influence the architecture of the
developing brain? - CORRECT ANSWERS-At any stage of development
Most traits and diseases in humans are derived from: - CORRECT ANSWERS-The
interaction between genes and environmental influences
Which of the following is an example of an epigenetic effect? - CORRECT ANSWERS-
An environmental factor modifies the area surrounding a gene such that its expression
decreases
Which gene has been shown to be epigenetically modified by the quality of maternal
care in rat offspring? - CORRECT ANSWERS-The glucocorticoid receptor gene
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? -
CORRECT ANSWERS-The stress response increases
