Sūkṣma śarīra (Subtle Body) Is An Interoceptive Map Of Central Nervous System Function

This is published in a very prestigious journal. It says its intersections and after a nadi system, that represents all aspects of the physiological condition of the body might provide a foundation for subjective feelings, emotions, self-awareness and I think from our perspective again, what’s fascinating is that, somebody in 2016 from the, one of the New York hospitals, I believe, published this, the “subtle body is an Interoceptive map of central nervous system function and meditative mind-brain-body integration”, a subtle body basically they said it had something to do with how the body was being mapped in the sensory nervous system.

So this is kind of how the brain sensory cortex looks. So this is called the primary sensory cortex. So these body parts that are made over here is basically in that part of the brain, this part of the body sensory input is being mapped and this is only one part of the brain, where the sensations are mapped but this is the most prominent part. So as you can see, there is like very disproportionate mapping right, like the hand is so big, the tongue and face are so big, the trunk, leg, foot, everything is very small. This is because obviously you have much more fine sensation in your fingertips and your face. Then you do in the back of, your back of your, where your hand or actually in your back. So this is called the Sensory Homunculus. It is a imagination of what the body would look like, if each body part was resized according to the amount of space devoted to it, in the sensory cortex. So as you can see the hands are very big because you sense it very well, the tongue is very big and other parts of the body are very small, because you don’t really spend that much brainpower processing sensation from there, so think about this. So the previous paper I said subtle body could be an Interoceptive map.

So, we know that in all our traditions, there this concept of sūkṣma śarīra. So, it’s the sūkṣma śarīra, really a representation of how the brain is viewing the body and this is not, I am not saying, this is equal to that figure because this figure is limited to external sensation as you can see, like you know, you don’t have anything for like heart, intestine. Those sensations also, a transmitted or brain. But this is a one, like only one sensory modality. So the sūkṣma śarīra, I would say is probably a more complex, more data rich, representation of the body. But in principle, I think they are on the right track and I think the sooner it really is how the brain really views the body.
