Brain Story Certification Exam 2025
Questions and Answers
the brain begins as an embryonic structure called the - ANSWER✔✔-neural tube, shortly after
conception it is formed in neurulation, all areas of the brain develop from here
the brain is considered mature around what age - 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
what is the sequence in which we learn our abilities - ANSWER✔✔-sensory, motor, emotional
skills, executive function skills (begin in early childhood but their sensitive period of development
continues into early adulthood)
what stages of development are the most plastic and the least - ANSWER✔✔-early childhood, late
childhood, adolescence, adulthood, the brain becomes progressively less plastic with age
the age at which a human has the most connections between neurons is - ANSWER✔✔-3, as the
brain ages, unused connections are pruned away and active connections are strengthened
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 behavioral development are all affected by social
interactions
