Question

Scientists claim that the connection between the brain and our sense of smell can help us avoid danger. What evidence can you find in the lesson to support the scientists' claim?

Consider the following in your response:

• How is the brain linked to the sense of smell?
• What is the link between the sense of smell and unpleasant feelings?
Write a minimum of three sentences.

Answer 1

The connection between the nose and the brain are governed by our sensory motor cells and neurons. Our senses (including the nose) send signal to our brain through the neurotransmitters. Similarly, the brain sends feedback to other senses and organs through the same media. This explains the unpleasant feeling we get when we smell something foul.
