I think it has to do with what we call emotions. The neurotransmitters of our brain that allow us to feel good, process information, and store it all in neurons and brain cells that then allow us to retrieve that information over and over again until our brain loses them. I've learned recently that not everyone has emotions or that some people
do have emotions but their neurons are wired much differently than others. It all depends on your dna, your cells, and your bodies overall ability to thrive and survive in this world. As you developed as a baby, and your brain started learning about the world. I'm still very interested in how the development of ones brain happens as they age from birth and I don't understand enough yet to state anything about it in this post. But I do understand that what we are born with and how it develops up until we are a young adult, is what we will be stimulated by for the rest of our adulthood. I've read that the ringing one hears when they've acoustically damaged their "hearing" and chronic pain are connected to some of the same regions in our brain.
I believe that some people logically experience this world and were born that way and then I believe there are many that emotionally experience this world. I'm not saying that those that were born with a logical brain don't experience emotions, but I'm speaking about the emotional information that's processed in those who were born with an emotional/creative side. Those who were born emotional, experience much of these emotions through their brain's ability to emotionally process sound. This happens through in-going auditory nerves between the brain's auditory region/limbic system and the hair cells of the cochlea. When these nerves are damaged and part of the brain's input to what allowed it to emotionally process outside information has been lost, then you're going to feel lower than what you would feel before. You aren't chemically receiving information to establish stronger neuronal growth in the Hippocampus like you were before. The connections between neurons in each region of the brain start to disappear as the neurons of the auditory system die out and disrupt the connections. I'm mean really, yes a sense like sight gives you the ability to express feelings of happiness as your brain visibly process movements and colors, but nothing is like our ability to "hear" sound. Sound is
SO complex. There is
SO much more information involved in sound and if you have the correct nerves to emotionally process it, you are going to feel good from the frequencies your hair cells pick up. It's the DNA we have and the functions of our brain that give us the wanting to survive in this world. I believe that damage to one's hearing or in other words, damage to the auditory nerves that allow neurotransmissions, causes the brain to switch it's course of actions. If not fully damaged, it's not going to logically process information yet. But the more you lose these in-going nerves of the auditory nerve, the more your brain loses part of it's strong connection to the limbic system (ex: amygdala) the more the brain will switch to using the Frontal lobes. This was discovered by a researcher apart of the University of Illinois speech and hearing science program. Here's where I believe the terms depression, cognitive deficits, stress, anxiety, etc. all come into play. The brain's plasticity can only go so far. If your brain was wired emotionally from birth, then you processed information through your hearing as you aged. If you were born with a logical brain, then you didn't have the wiring of neurotransmitting nerves/neurons from your limbic system to your inner ear. An emotional brain received it's information from it's ability to pick up sound. Damage to that ability to emotionally process information through sound causes a hole to be established. The brain's plasticity can't fix that hole. That's why in Alzheimers, it's said that the brain loses matter from the inside and towards the outside. It's not emotionally creating enough neurons to keep it's matter continuously growing. Those who were born with a logical brain, I believe, were wired from birth to emotionally experience and process this world and make decisions much more from their frontal lobe than the limbic system. It's the amygdala that allows emotional brains to recall and decide what to do. Fight or flight as it's called. It also has to do with the brain's sexual processing abilities but I won't talk about that.
Sorry if I didn't really answer your question but I like to type out just what logically flows out of my brain now. Still trying to understand what has happened to my brain through my "hearing damage".
I was born with an emotional brain, now with what happened, I experience the world logically. It's my quest to get back to the old me. That motivates me into figuring out new information about the brain, one's hearing, and emotions.
