Worked Solution & Example Answer:The diagram below represents areas of high activity in a part of the brain of an individual as a task is described to them which they then complete - Scottish Highers Human Biology - Question 9 - 2016
Step 1
Step 2
Explain how the diagram supports the suggestion that there is localisation of function in the brain.
Answer
The diagram illustrates that different areas of the brain are active during various aspects of the task, indicating that specific regions are responsible for distinct functions. For example, the sensory area is active while receiving signals, while the motor area is engaged during the completion of the task.
Step 3
Explain the high level of brain activity during the description of the task.
Answer
The high level of brain activity during the description of the task can be attributed to the processing of auditory and visual information. Specifically, areas of the brain involved in understanding language and processing sensory inputs are activated.
Step 4
Explain why the diagram shows high levels of activity in the sensory and motor areas.
Answer
Sensory area: The individual was touching or feeling the paper, which requires sensory input from tactile receptors.
Motor area: The individual was using muscles in their hands/fingers to fold the paper, necessitating significant motor control and coordination.
