Question

You are researching how our brains respond to music.

1. What general region (lobe) of the brain are you interested in?

2. You want to know whether activation in the primary auditory cortex is necessary for discriminating between two pitches in human participants. What method will you use to investigate this question and why?

3. As a follow-up experiment, you want to understand how quickly our brains can detect a mistake in a musical passage. You plan to compare how the brain responds to musical passages with and without mistakes. What method will you use to investigate this question and why?

Explanation / Answer

1. Temporal lobe has primary auditory area, so it is of interest for any activity in brain related to hearing.

2. We can use fMRI ( functional magnetic resonance imaging). It us a non invasive procedure and activities can be visualised at the same time when any stimulus is provided or two different pitches are provided. If there is any activity seen in fMRI in primary auditory area during the pitches, it means that it is necessary for differentiation.

3. Again fMRI can be used. We provide some music with mistake and see if there is any activity in frontal lobe and parietal lobe because it contains areas of thinking, planning like finding mistakes.
