Draw your own brain activity picture, like on pg. 143

Why did Carl Zimmer get his brain scanned?

• to help him recollect childhood memories

• because the neuroscientist Van Wedeen asked him to

• to aid him in reporting on how the brain works

• because he wants to learn to suppress feelings of panic

What did he mean by his response?

• He can't answer that because it's not ethical to

• He doubts he would do it since it would cause so much pain.

• He finds it funny that people would suggest that since the mice died in the process.

• He doesn't think about it much because it would be such a huge challenge.

When mapping genes, what do researchers at the Allen Institute do last?

• cut the brain into thin sections

• apply chemicals to reveal active genes

• scan the brain of a dead person

• mount brain slices on glass

How does Carl Zimmer feel about the work of Karl Deisseroth?

• He feels it's amazing, as even other scientists are impressed.

• He finds it impressive, even though most scientists are skeptical.

• He finds it interesting, but worries it may not be practical.

• He thinks his work has not been fully appreciated by other scientists.

In paragraph K, the phrase in check is closest in meaning to ________.

How was Cathy Hutchinson able to raise a coffee cup?

• She controlled a machine using verbal commands.

• Wires carried signals directly from her brain to the cup.
