Brain Story Certification Questions with Correct Answers (Grade
A+)
Question 1: 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
Question 2: 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
Question 3: 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)
Question 4: 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
Question 5: 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
Question 6: how do experiences shape the developing brain
Answer: they influence which neural connections are strengthened or pruned, they help us practice our skills
Question 7: 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
Question 8: most traits and diseases in humans are derived from
Answer: the interaction between genes and environmental influences
Question 9: what is an example of an epigenetic effect
Answer: an environmental factor modifies the area surrounding a gene such that expression decreases
