Brain Development, Did You Pay Attention?
The human brain begins forming very early in prenatal life but it is considered to be a lifelong process with no end. Some people believe that the brain is fully developed at the age of 25. Did you pay attention in class as we covered brain development? Take up the quiz below and get to find out.
Questions and Answers
- 1.
Does the male or female brain usual weigh more?
- A.
The female brain
- B.
The male brain
Correct Answer
B. The male brainExplanation
Since the male body is usually larger, so is the male brain.Rate this question:

What is the neural tube's function?
- A.
To create synaptic connections
- B.
To make neurons migrate
- C.
To make the spinal cord
- D.
To produce all neurons in the human brain
Correct Answer
D. To produce all neurons in the human brainExplanation
The neural tube's function is to produce all neurons in the human brain. The neural tube is a structure that forms during embryonic development and gives rise to the central nervous system, including the brain and spinal cord. It serves as the foundation for the development of neurons, which are the building blocks of the brain. Through a process called neurogenesis, the neural tube generates a vast number of neurons that eventually form the complex network of the human brain.Rate this question:

What sense is developing slower than all other senses until 3 months?
- A.
Taste
- B.
Touch
- C.
Smell
- D.
See
- E.
Hear
Correct Answer
D. SeeExplanation
The sense that develops slower than all other senses until 3 months is the sense of sight. This is because newborn babies are not born with fully developed vision and it takes time for their eyes and visual system to mature. Initially, their vision is blurry and they can only see objects that are very close to their face. As they grow and their visual system develops, they gradually gain the ability to see objects at a distance and perceive more details in their surroundings.Rate this question:

What side of its brain does a baby uses to respond to language until it reaches 1 year old?
- A.
Left
- B.
Right
- C.
Both
- D.
Neither
Correct Answer
C. BothExplanation
Babies use both sides of their brain to respond to language until they reach 1 year old. At this stage, the brain is still developing, and both hemispheres are involved in processing and understanding language. As the baby grows and language skills develop, there is a gradual specialization of language functions to the left hemisphere of the brain, which is typically the dominant side for language processing in adults. However, during the first year, both sides of the brain are actively involved in language acquisition and comprehension.Rate this question:

What did I describe as a "window of opportunity" during my keynote?
- A.
Synaptic pruning
- B.
Critical Periods
- C.
5 years old
Correct Answer
B. Critical PeriodsExplanation
The correct answer is Critical Periods. Critical periods refer to specific time frames in development when certain skills or abilities are most easily acquired. During my keynote, I described critical periods as a "window of opportunity" because they represent crucial periods in a person's life when they are most receptive to learning and developing specific skills. These critical periods are characterized by heightened brain plasticity and are essential for the optimal development of various cognitive, linguistic, and social abilities.Rate this question:

What is a way you can help your child develop speech skills?
- A.
Talk to your child
- B.
Give your child junk food
- C.
Ignore your child
Correct Answer
A. Talk to your childExplanation
Talking to your child is a way to help them develop speech skills. Engaging in conversations, reading aloud, and using descriptive language can enhance their vocabulary, comprehension, and communication abilities. By actively communicating with your child, you create an environment that encourages language development and fosters their speech skills.Rate this question:

About how many of the original neurons are left in the brain when you are a teenager?
- A.
None of them
- B.
All of them
- C.
Half of them
Correct Answer
C. Half of themExplanation
During teenage years, the brain undergoes a process called synaptic pruning, where unnecessary connections between neurons are eliminated to increase efficiency. This process results in the elimination of approximately half of the original neurons, allowing the remaining ones to strengthen and form more efficient neural pathways. Therefore, the correct answer is "Half of them."Rate this question:

helps speed up brain development.
Correct Answer
Music
Puzzles
Being spoken toExplanation
Engaging in activities such as music, puzzles, and being spoken to can help speed up brain development. These activities stimulate different areas of the brain, promoting cognitive growth and enhancing various skills. Music, for example, has been shown to improve memory, attention, and language abilities. Puzzles, on the other hand, enhance problem-solving and critical thinking skills. Being spoken to, especially in early childhood, helps develop language and communication skills. Overall, these activities provide mental stimulation and contribute to the overall development of the brain.Rate this question:

slows down brain development.
Correct Answer
Junk food
Being ignored
Drugs
AlchoholExplanation
The given answer options consist of various factors that can potentially slow down brain development. Junk food, being ignored, drugs, and alcohol can all have negative effects on the brain and hinder its development. Junk food lacks essential nutrients that are necessary for proper brain function and growth. Being ignored can lead to feelings of isolation and neglect, which can negatively impact brain development, especially in children. Drugs and alcohol can cause severe damage to the brain and impair its functioning.Rate this question:
