This will be one of the most “scattered” post of this blog, I bet.
First, not talking of brain or supercomputers at all, I am fascinated by Europe’s “big and bigger” science projects. Suddenly it reminds me of late days of Harshavardhana of bigger and bigger donation to Bauddha sangha; late Mughal period’s preoccupation with bigger buildings; late Maratha period’s obsession for bigger wars and late British Raj’s ever bigger government.
Now back to science.
Just like weather mapping, brain mapping will be next to impossible. After all human brain is a very complex, interconnected, multi-input, multi-dimensional, analog system. In weather prediction case, the research nearly died after they realized it is a deterministic chaotic system. The same will hold true for human (or even rat) brain.
Now a bit away from science – almost near to a spiritual guru business.
I predict that a successful brain mapping will find a few structures pretty comparable to samkhya system, with difference I note here. I will first go by samkhya order
- indreeya system – the physical stimulus-response system, related to sensory signals and actuation. We know, while Kapila rishi lumped it in one name, actual brain has different areas even for sensory interpretation – and completely different areas for motor actuation
- manas system – the constant (and according to Kapila, random) generation of thoughts, ideas. I predict, it will turn out to be first order Markov linked with indreeya or linked with “inertia” of the brain state, more later in the post
- buddhi system – the intellect – normal logical, pattern recognition, linguistic, mathematical, goal seeking etc. Once again, unlike Kapila, two different abilities are already found in two different hemispheres of brain
- citta system – according to Kapila, likes and dislikes. Psychology has terms like “inhibition”, if I am correct
- ahamkaara system – ego
Now, let me take a role of full-time Baba Science-anand and express how I feel around my own brain. I start in reverse direction from Kapila. This is how they might find if they model or monitor my brain
- This ego E, is experienced two ways:
- first, as a ratio of physical time versus psychological time. When things go as per your ego, time seem to move faster. That is, E = phy(t)/psy(t)
- second, E is also a curl, or focus of reflection of chitta
- chitta can be thought of a collection of freely orientable infinitesimal mirrors, shone by the light or indreeya system
- manas is probably divergence of the chitta. I have been away from vector calculus for quite some time. So I am unable to think clearly. However, thinking over non-substantial items is futile – so I believe manas is like flux.
- ichchhaa or will/wish, W, generally considered to be divine and unexplainable, is simple dE/dt. Because W is like velocity, typically we don’t get what we wish – but it is necessary to go in that direction. Buddhists advise to make W = zero to see the truth – or static, instantaneous state of mind
- There are three types of chronological inputs to chitta through indreeya – samvedana (for t = 0), smrti (for t < 0) and kalpanaa (for t > 0)
- Newton’s first and third laws of motion or homeostasis hold for status of brain. This homeostasis is identical to ahamkaara or ego or E
- If the reflection of chitta (reality) is pointing away from W, we get negative feelings – like anger (for t = 0), vengeance (for t < 0) or fear (for t > 0). If the reflection is pointing along W, we get positive feelings – like enthusiasm (for t = 0), nostalgia (for t < 0) or hope (for t > 0)
- Now, this buddhi system is confusing to me too. I lack term for the entity here – let us call it Q. Q for t = 0 is buddhi B. For t > 0 it is praj~na (foresightedness) P and for t < 0, it is anubhava (experience), A.
- By and large, buddhi B and dhyaana are related. Another term, medhaa (talent) is probably dB/dt
- Newton’s second law of motion is also true. One needs to spend efforts to change the environment according to W. This means Q, whose function is to protect E and/or W – I am not sure, acts like a force. This force is kind of inverse square of distance. The farther a perception is, the less it acts. For example, a comet slamming Jupiter attracts less intellect and attention and problem solving than a stone falling on your head.
- And because Q is protecting E or W, it has to consider ahimsaa as the path of least resistance
- Now, this is a normal brain. It doesn’t explain delirious state or suicidal tendencies 🙂 It doesn’t explain even martyrdom – or how people sacrifice E for something extrinsic – like religious beliefs or nation
I know vector calculus turns a lot of readers away – and so does metaphysics. Still, my patient reader till the end of the post, do you agree? I know it will take you years to reply in Boolean terms. Still, I will wait for your feedback!
