The Brain: Damage Response and Brain Hemispheres 1.4c

Which part of the brain is responsible for facial recognition?

The temporal lobe

How does neuroplasticity help people who are blind or deaf?

It repurposes unused brain areas for other functions, like enhancing touch or hearing.

What happens when a slow-growing left hemisphere tumor disrupts language?

The right hemisphere can adapt and take over language functions.

What is neurogenesis?

The process of producing new neurons.

What are stem cells?

Cells that can develop into any type of brain cell

What is the corpus callosum?

A wide band of axon fibers connecting the two brain hemispheres and enabling communication between them.

How does split-brain surgery affect visual processing?

Each eye sends information to the opposite hemisphere, and without the corpus callosum, the two hemispheres cannot share this information.

How does the left hemisphere behave after split-brain surgery?

It tries to rationalize actions controlled by the right hemisphere, even without understanding them.

Which hemisphere excels in making inferences and understanding context?

The right hemisphere.

What is Weber's Law?

To perceive a difference between two stimuli, they must differ by a constant percentage, not a fixed amount.

What happens when a person performs mathematical tasks?

The left hemisphere becomes more active.

What is the relationship between sensory adaptation and perception?

Sensory adaptation reduces sensitivity to repeated stimuli, allowing the brain to focus on new or important changes in the environment.

How does split-brain surgery stop seizures?

By severing the corpus callosum, abnormal brain activity can no longer bounce between hemispheres, stopping the seizures
