Exploring the Human Brain

What is the largest part of the human brain?

• Cerebellum

• Cerebrum

• Brainstem

• Thalamus

Which part of the brain is primarily responsible for balance and coordination?

• Cerebrum

• Medulla Oblongata

• Cerebellum

• Hypothalamus

Identify the lobe of the brain associated with processing visual information.

• Frontal Lobe

• Parietal Lobe

• Temporal Lobe

• Occipital Lobe

Explain how the hippocampus is involved in memory formation.

• It stores long-term memories.

• It processes and retrieves memories.

• It encodes and consolidates new memories.

• It deletes unnecessary memories.

Which cognitive process involves the ability to focus on specific stimuli while ignoring others?

• Memory

• Attention

• Perception

• Language

Describe the role of neurotransmitters in cognitive processes.

• They transmit signals between neurons.

• They store information in the brain.

• They protect neurons from damage.

• They regulate blood flow in the brain.

How does chronic stress impact the brain's structure?

• It increases the size of the hippocampus.

• It enhances the growth of new neurons.

• It can lead to the shrinkage of the prefrontal cortex.

• It strengthens synaptic connections.

What is the primary function of the amygdala in the brain?

• Regulating sleep cycles

• Processing emotions

• Controlling voluntary movements

• Managing sensory information

Analyze how stress affects cognitive functions such as memory and decision-making.

• Stress improves memory recall and decision-making speed.

• Stress has no effect on cognitive functions.

• Stress can impair memory recall and lead to poor decision-making.

• Stress enhances cognitive flexibility and problem-solving skills.

Which part of the brain is involved in the regulation of the autonomic nervous system?

• Thalamus

• Hypothalamus

• Amygdala

• Hippocampus
