I need help answering the following 4 questions. Thank you in advance for providing better insight.

1. Compare and contrast place theory and frequency theory and describe the association between frequency, action potential, and axons.

2. Does the auditory cortex play a role in pitch perception? If so, describe; if not, why? Also, what happens to a person's pitch if their auditory cortex is damaged?

3. What happens when a person can't differentiate among sounds of different frequencies?

4. Compare and contrast chemical senses and mechanical senses, discuss their differences and similarities, and describe how they impact the sensory system and it's functions.
