1 markThe brain contains many different regions that each carry out different functions.
Which of the following functions correctly matches each region of the brain?
| Cerebrum | Cerebellum | Hypothalamus | Medulla Oblongata | |||
| ☐ | A | Involved with conscious activities such as vision, hearing and thinking | Enables dancing, playing musical instruments and keeping our balance | This is where functions such as breathing and heart rate is controlled | Plays an important role in homeostatic mechanisms such as thermoregulation | |
| ☐ | B | Enables dancing, playing musical instruments and keeping our balance | Involved with conscious activities such as vision, hearing and thinking | Plays an important role in homeostatic mechanisms such as thermoregulation | This is where functions such as breathing and heart rate is controlled | |
| ☐ | C | Plays an important role in homeostatic mechanisms such as thermoregulation | This is where functions such as breathing and heart rate is controlled | Involved with conscious activities such as vision, hearing and thinking | Enables dancing, playing musical instruments and keeping our balance | |
| ☐ | D | Involved with conscious activities such as vision, hearing and thinking | Enables dancing, playing musical instruments and keeping our balance | Plays an important role in homeostatic mechanisms such as thermoregulation | This is where functions such as breathing and heart rate is controlled |
4 marksScientists use a variety of different equipment and techniques to study the brain in a non-invasive manner. Magnetic resonance imaging (MRI) and functional MRI (fMRI) are two of these techniques that can be used to study the brain.
Compare and contrast these two techniques.
2 marksThe visual cortex which is located in the outer layer of the cerebrum, develops during the critical period.
Explain the importance of the critical period in the development of the visual cortex.
2 marksStudies regarding the development of the visual cortex was carried out by Hubel and Wiesel during the 1960s and 1970s. They used animals to model the effects of their experiments on the development of the visual cortex. The use of animals in scientific research remains controversial.
State two arguments against animal research.
