I kinda agree with your college professor. I also believe our brain is nothing more than a sophisticated antenna capable of receiving and also transmitting signals. After all, look at what our brain actually is, emulsified oils and other material elements (matter). In fact we are consciousness, trapped, bonded to Matter. Our body is Matter (Nature). So, our brains is Nature. Our mind is consciousness dancing across the electrical Nature of our brain and body.

Thinking can't and doesn't happen in the brain. It takes place somewhere else, which means you (your body & soul) is just one dimension of who you really are. The one that consciousness manifested in this reality we call Matterium (from matter). Your other dimension "the Thinker" is in the "Cloud" for lack of a better word. Think of this how AI is constructed and operates, after all they built AI based on the way humans were created. You interact with ChatGPT (AI) on your desktop or mobile device, that's the application, or receiver/sender mechanism. The computation & execution based on defined algorithm(s) happens somewhere else (the Cloud).
