The reason that we can rely on fMRI to measure brain activity is because

Descartes and other philosophers have pondered a thought experiment known as the ___________________, which relies on a disembodied brain.

How would you set up an experiment (similar to those performed by Ehrlich and Goldman) to test whether neural tissue is protected from molecules circulating in the bloodstream? Indicate which step would NOT be necessary.

Predict whether the technique called "carbon dating for neurons" will likely replace methods based on artificial thymidines in modern research labs. Justify your response.

Fill in the blank with UNIDIRECTIONAL or BIDIRECTIONAL. In general, the brain's principal arteries and surface arterioles are _____________________, but the penetrating arterioles are _____________________ with regard to the direction of blood flow.

Examine figure 5-22. In the text The reason you can take your pulse in your carotid artery on one side of your neck and not cause ischemic injury is because

Predict what would happen if you injected a hydrophilic (polar) drug directly into the CSF.

The picture below is a hippocampal section from an animal injected with tritiated thymidine shortly after birth and sacrificed two weeks later. What can you conclude from this image?

Examine the evidence that the central nervous system is "immune privileged". What is a central observation that leads to this idea?

Predict what would happen in the arachnoid membrane if the cells of the arachnoid barrier had fewer tight junctions.

An ultrasound of a 6 month old fetus shows abnormally large brain ventricles, similar to the image found in Figure 05-09. In the text One cause of this might be
