Some thalamic-cortical connections are widely (and historically) well known. Like its input to layer 4, while other cortico-cortical connections are not so widely examined (there are few trace studies here and there). One of the tenets of TBT, is attachment of reference frames to each sensory input (as well as up into any hierarchy.
Now into my intuitive proof. It has to do with Qualia. Just a little explanation to direct everyone to the same page. When people talk about consciousness they mean a lot of different things. Generally, self-awareness, subjective-experience and qualia are some of these things.
Let’s further break down the concept of qualia. Qualia itself, can be broken down to all the different sensory feelings. The redness of red, painfulness of pain, emotions, and so on …
Of these different qualias, one caught my eye a few month ago. EVERY one is having an out of the body experience every moment of their lives. Close your eyes, and touch something (closing your eyes is not necessary but will help), you will feel something at the tip of you finger.
That’s SO weird. your brain is generating a learned map of your touch outside your body ( you feel the touch at exact point that your body has learned). You can close your eyes, and touch something, you can still be damn sure of exact spatial (vector) of the point of your touch, as if your brain is attaching a reference Frame (which must have been learned to your sensory input (not necessarily learned)). Now, if that’s true for a finger touch, then it must be true for other sensory inputs, such as vision (or maybe its attached at perception level).
Now we all know about phantom hand, and it takes a long time to learn new reference frames.
Thought to share this as it really does feel like an intuitive proof of reference frames attachment to any sensory input.
