Brain Story Certification Questions and
Correct 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
