Facts about brain

What are the main parts of the brain and their functions?

• Thalamus (memory, emotion)

• Hypothalamus (vision, hearing)

• Limbic System (speech, language)

• Cerebrum (thought, action), Cerebellum (movement, balance), Brainstem (breathing, heart rate)

How does the cerebral cortex contribute to brain function?

• The cerebral cortex contributes to brain function by processing sensory information, controlling voluntary movements, and enabling cognitive functions.

• The cerebral cortex is involved in the production of hormones.

• The cerebral cortex is responsible for regulating heart rate.

• The cerebral cortex primarily manages digestive functions.

What role does the brainstem play in regulating bodily functions?

• The brainstem regulates emotional responses and memory.

• The brainstem regulates vital bodily functions like heart rate, breathing, and blood pressure.

• The brainstem controls voluntary muscle movements.

• The brainstem is responsible for processing visual information.

At what stage does the human brain reach its peak size?

• Around age 2 to 3 years

• During adolescence

• Around age 5 to 6 years

• At birth

What are the key stages of brain development in infancy?

• Language acquisition stages

• Motor skill development phases

• Sensory perception milestones

• Key stages of brain development in infancy include neural connection formation, myelination, and regional brain development.

How does synaptic pruning affect brain development?

• Synaptic pruning refines neural connections, enhancing brain efficiency and cognitive development.

• Synaptic pruning primarily occurs in adults, not during early brain development.

• Synaptic pruning has no impact on cognitive abilities or brain structure.

• Synaptic pruning increases the number of neural connections, leading to greater brain complexity.

What is neuroplasticity and why is it important?

• Neuroplasticity is the brain's ability to remain static and unchangeable.

• Neuroplasticity is the brain's ability to reorganize itself by forming new neural connections, and it is important for learning, recovery from injuries, and adapting to new experiences.

• Neuroplasticity is the process of losing neural connections over time.

• Neuroplasticity refers to the brain's inability to recover from injuries.

How do environmental factors influence brain development?

• Environmental factors only influence physical health, not brain development.

• Brain development is solely determined by genetics.

• Environmental factors influence brain development by affecting nutrition, exposure to toxins, social interactions, and physical activity.

• Environmental factors have no impact on brain development.

What are the differences between the left and right hemispheres of the brain?

• Both hemispheres are identical in function and processing.

• The left hemisphere is more analytical and language-oriented, whereas the right hemisphere is more creative and spatially aware.

• The left hemisphere is responsible for emotions, while the right hemisphere handles logic.

• The left hemisphere controls the left side of the body, while the right hemisphere controls the right side.

How does the brain change during adolescence?

• Synaptic growth is the primary change in the adolescent brain.

• The limbic system matures faster than the prefrontal cortex.

• The brain undergoes synaptic pruning and myelination, with the prefrontal cortex maturing more slowly than the limbic system.

• The brain remains unchanged during adolescence.
