provide a way to measure the functioning and activity of the
brain.

provide detailed computerized interpretations of brain
dysfunctions.

produce black and white scans of the brain’s structures.

create selective injuries that allow researchers to study
brain function.

What is a biological reason for why heroin is addictive?

The bodies of heroin users do not produce endorphins, so
withdrawal is very painful.

Neurotransmitters are damaged and continue sending
stimulating messages to cells.

It produces an excess of dopamine in the brain.

Heroin bonds with serotonin, producing mental confusion in
users.

pipeline.

little brain.

triage nurse.

seahorse.

23)
Which statement most accurately explains the difference in
functioning between the right hemisphere of the brain and the left hemisphere?

The right specializes in logical thought processes.

The right processes information all at once, whereas the
left breaks things down into parts.

The right processes information from the right side of the
body, whereas the left processes information from the left side.

The right sees things upside down, whereas the left sees
them right side up.

24
