Which modern technology has allowed neurobiologists to study brain functions in a way that does not require directly accessing the brain?

• dissection

• brain tissue microscope slides

• magnetic resonance imaging (MRI)

Answer explanation

DIRECTLY accessing the brain requires physically manipulating the brain structure in some way. MRI uses technology to take images of the brain. No invasive techniques are required.

How are messages transferred through the brain?

• by neurons transmitting electrical signals

• by blood cells moving through arteries

• though air spaces surrounding the brain

Answer explanation

Messages are transferred through the brain by neurons which transmit electrical signals. These are known as nerve impulses.
