Welcome. The two questions are related, but are different enough to warrant two separate questions. This will greatly enhance their answerability. Secondly, I would recommend to add some prior research to narrow the scope. I'm saying, because the first question contains a faulty supposition -- ion channels in sensory receptors are not connected to the brain at all. Answering the questions therefore will need a basic outline of neuroscience (what is an ion channel, a receptor, a neuron, an axon, projections to the brain etc etc) before we can even get to the answer.

Questions need to be focused. As of now we need to write down an entire Introduction to Neurosci for you. I recommend [Khan Academy](https://www.khanacademy.org/science/health-and-medicine/nervous-system-and-sensory-infor), which has great introductory material in this area that is freely accessible .

# Question about the role of the sensory receptors compared to the sensory cortoces

(Asked by: username_0 on 2020-06-13)

I have two questions regarding the fact that each sensory receptor has its specific ion channels that open in response to a specific stimulus (for example, ion channel that opens when streching for somatosensation), and is connected to correspondent sensory cortex.

1. Did our sensory system developed perfectly so that each ion channels in the sensory receptors are connecting to the corespondent sensory cortex? If not, can you elaborate and give examples?
2. Theoretically, what would happen if they weren't corresponding? And specific, if for example, we had sound receptor that was connected to the visual cortex?

Thanks!
