D)that demonstrate how certain brain circuits connect to produce behavior.

Question

Quizplus · Accepted Answer

Functional magnetic resonance imaging (fMRI) can capture changes in brain activity by measuring changes in blood oxygen levels in the brain. As blood flows to areas of the brain that are active, it brings fresh oxygenated blood, which increases the level of oxygen in those areas. fMRI can detect these changes many times a second, allowing researchers to study brain activity during a variety of tasks and behaviors.

Answer: D
 fMRI can also show how different brain regions are connected and communicate with each other to produce behavior. By studying how blood flows between different brain regions while a person performs a task, researchers can identify networks of brain regions that are involved in different types of cognitive processes, such as attention, memory, or decision-making. These networks can provide insights into the underlying neural mechanisms of behavior and help develop new treatments for brain disorders.
