Accepted Answer

A taxi driver develops enlarged brain areas related to spatial memory after years of navigating city streets.

Question 6

Which equation best represents the change in electrical charge during an action potential?

Accepted Answer

$$\Delta V = V_{rest} \rightarrow V_{threshold} \rightarrow V_{peak}$$

Question 7

Question 11

Which of the following best describes the role of mirror neurons in human behavior?

Accepted Answer

They are activated both when performing an action and when observing the same action in others.

Question 12
