The video discusses the structural differences between human and mouse brains, highlighting the smoothness of the mouse brain compared to the folded human brain. It explains that these folds are a result of evolutionary growth, allowing a larger brain to fit within the skull by increasing surface area relative to volume. The video also introduces the jewel wasp, a parasite capable of performing brain surgery on its host.

What is a key difference between the human brain and a mouse brain?

• The mouse brain has more folds.

• The human brain has grooves and valleys.

• The human brain is smaller.

• The mouse brain is larger.

Why did the human brain develop folds over time?

• To increase its weight.

• To enhance its smoothness.

• To improve memory capacity.

• To fit within the skull as it grew larger.

What problem does the folding of the brain help solve?

• The memory retention problem.

• The energy consumption problem.

• The surface area to volume problem.

• The weight distribution problem.

How does the folding of the brain affect its structure?

• It makes the brain heavier.

• It allows more cortex to be packed.

• It makes the brain smoother.

• It reduces the brain's surface area.

What unique ability does the jewel wasp have?

• It can perform brain surgery on its host.

• It can smooth out brain folds.

• It can shrink the brain.

• It can increase brain size.
