Question 1

Role/ Function of the Frontal lobe

Answer 1

• Control panel of our personality and ability to communicate
• Motor area which controls movement in specific parts of the body

Question 2

Role/ Function of the Parietal lobe

Answer 2

• Processes sensory & visual information (e.g. language / mathematics)
• Somato-Sensory area (sense of touch)

Question 3

Role/ Function of the Occipital lobe

Answer 3

• Primary visual area which coverts impulses from retina into sight

Question 4

Role/ Function of the Temporal lobe

Answer 4

• Processes information about temperature, taste, touch and movement

Question 5

What is brain lateralisation?

Answer 5

• The two halves of the human brain are (completely dissimilar/not exactly alike/ exactly alike)
• Each hemisphere has functional specialisation
  e. g. the left is dominant for language and the right excels at visual motor tasks

Question 6

What are the two hemisphere’s connected through nerve fibres called?

Answer 6

Corpus Callosum

Question 7

Role of the Corpus Callosum

Answer 7

Facilitates interhemispheric communication - Allows the left and the right hemispheres to ‘talk to’ one another.

Question 8

What is a Circadian rhythm?

Answer 8

• A type of biological rhythm subject to a 24 hour clock

- They are endogenously generated, although they can be modulated by external cues such as sunlight and temperature.

Question 9

What is the Suprachiasmatic nuclei (SCN)

Answer 9

• Controls the timing of the sleep-wake cycle
• Coordinates this with circadian rhythms in other brain areas.
• Lies in the hypothalamus

Question 10

What is homeostasis?

Answer 10

• Sleeping and wakefulness can be determined by homeostasis
• When an individual has been awake for a long time, homeostasis tells the body there is a need for sleep because of energy consumption

Question 11

What is an Exogenous Zeitgeber

Answer 11

• Influence biological rhythms
• These can be described as environmental events that are responsible for resetting the biological clock of an organism
• Most important Zeitgeber is light

Question 12

Why is light the most important Zeitgeber?

Answer 12

Because it is responsible for resetting the body clock each day, keeping it on a 42-hour clock

Question 13

What is an Endogenous Pacemaker?

Answer 13

• Internal mechanisms that govern biological rhythms
• In particular the circadian sleep cycle
• Internal biological clocks, they can be altered & affected by the environment

Question 14

What is the most important endogenous pacemaker?

Answer 14

Suprachiasmatic nuclei (SCN)
