Likely a prefrontal cortex, the administrative center of the brain and generally host to human consciousness. As well as a dedicated memory system with learning plasticity.
Humans have systems that mirror llms but llms are missing a few key components to be precise replicas of human brains, mostly because it’s computationally expensive to consider and the goal is different.
Some specific things the brain has that llms don’t directly account for are different neurochemicals (favoring a single floating value per neuron), synaptogenesis, neurogenesis, synapse fire travel duration and myelin, neural pruning, potassium and sodium channels, downstream effects, etc. We use math and gradient descent to somewhat mirror the brain’s hebbian learning but do not perform precisely the same operations using the same systems.
In my opinion having a dedicated module for consciousness would bridge the gap, possibly while accounting for some of the missing characteristics. Consciousness is not an indescribable mystery, we have performed tons of experiments and received a whole lot of information on the topic.
As it stands llms are largely reasonable approximations of the language center of the brain but little more. It may honestly not take much to get what we consider consciousness humming in a system that includes an llm as a component.
You mentioned being unable to afford diagnosis, so mental healthcare is likely out of the question. This sort of thing is probably better handled by professionals but I’ll offer some perspective regardless.
I’m not neurodivergent, though it’s likely that everyone is a little “on the spectrum” because that’s kinda how spectrums work. Because our brains may be wired slightly differently I’m not sure my thoughts will be as valid or valuable to your situation.
It’s my opinion that there is no fundamental “self”, and rather believe your self image is merely a reflection of all of your prior actions. This generally means that masking is not really a fundamental change in behavior from your “true self” but is rather a step in actually changing what you perceive yourself as.
Fake it til you make it is a terrible saying, but it does apply here.
I act differently with every person I interact with, I adapt to who they are and their values, this adaptation is not what I would consider masking though perhaps you would. Due to this simple system of adaptation most of my peers would consider me well liked and successful.
There are some fundamental rules that I won’t adapt into, moral boundaries that I don’t cross, but as long as it’s benign I have no problem being a sports fan with some crowds, a strong rights activist among liberal audiences, a sweet person to my grandparents. All of these are parts of who I am but the part of me that gets shown to each person isn’t necessarily the whole picture.
It is important to be comfortable with your own actions, if it feels fake and disingenuous to act differently around different people then why force it? Life is about enjoying who you are, where you are, and what you’re doing. Learn to experience and accept your current situation and stuff like this won’t matter.
