BRAIN STORY CERTIFICATION TEST 2025
QUESTIONS AND ANSWERS.
1. Which gene has been shown to be epigenetically modified by the quality
of maternal care in rat offsrping - Correct answer-the glucocorticoid
receptor gene which is methylated in response to maternal care
2. 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 - Correct answer-the stress response
increases
3. What pre-existing conditions are associated with epigenetic modification
of the glucocorticoid receptor gene in victims of suicide - Correct
answer-childhood maltreatment
4. Which aspect of development is NOT affected by social interactions -
Correct answer-cognitive, social, emotional, language, physical and
behavioral development are all affected by social interactions
5. Human infants need to be taught how to react to social causes by -
Correct answer-nothing- infants have an innate response to social cues

6. What is meant by a "serve and return" interaction - Correct answer-it is
the interaction between a child and adult where various activities and
communication pass back and forth
7. The brain begins as an embryonic structure called the - Correct answer-
neural tube, shortly after conception it is formed in neurulation, all areas
of the brain develop from here
8. The brain is considered mature around what age - Correct 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
9. What is the sequence in which we learn our abilities - Correct answer-
sensory, motor, emotional skills, executive function skills (begin in early
childhood but their sensitive period of development continues into early
adulthood)
10. What stages of development are the most plastic and the least -
Correct answer-early childhood, late childhood, adolescence, adulthood,
the brain becomes progressively less plastic with age
11. The age at which a human has the most connections between
neurons is - Correct answer-3, as the brain ages, unused connections
are pruned away and active connections are strengthened
