Synthetic Reflexes provide an engineering

The brain is made of matter. Matter is subject to the laws of physics. Even just Newtonian mechanics may be sufficient. Nothing specifically quantum is needed for this research since operations appear to be properties of material arrangements. Knowledge of signals and systems is also useful. If it seems not obvious how to make a brain, it is because the patterns by which the laws of physics are employed to make a brain have not been published and turned into laws of brain physics.

Vertebrate neurons host two modes of communication.

Myelinated axons host single high velocity Hodgkin and

Huxley membrane action potentials at  ̃100m/sec. Tasaki observed
 +
a low velocity adiabatic pulse at  ̃1m/sec. Those axons contain
 +
many thousands of neurofibrils each hosting a separate pulse.

Neurofibril hosted information processing embodies a superset

of vector math.

On a dendritic spine, a coincident common

Combined scalar clouds from neurons of one species form

manifolds. Each manifold is a property map hosted within a

manifold-combining neuropil. Intersecting manifolds provide inputs

form historical coherencies into compound manifolds.

This has been my specific arena of amateur science since 2002, and I have made some progress. Quite a bit can be speculated from available literature. I have my MIT physics degree, electronics training, software skills, experience visualizing scientific data, and substantial experience with studying neurons and reflex systems, so I have a decent set of tools with which to continue.

Neural organs comprise layered neuropils hosting layered manifolds.
 +
Projections from compound manifolds enable reviewing pasts
 +
and predicting futures. Compound manifolds are the interface
 +
between sensation and actuation. Intention generates a manifold
 +
against which proprioceptive and sensory manifolds intersect,
 +
causing differential actuations. Actuations are triggered through
 +
a distributor to avoid violations of muscle twitch unit duty
 +
cycle requirements.

Having had an epiphany on October/2/2018 I have been designing a synthetic reflex system which will be used in a simple robot. My goal is to endow the robot with reflexes having operations indistinguishable from living systems; no matter how deeply you drill down until you reach the material from which it is comprised. Then, of course, "the brain is the crowning achievement of the reflex system." (Sir Charles Sherrington, Nobel Medicine 1932).
+
Neuron, neuropil, and organ shapes enforce
 +
constraints for dynamic mobile manifold shapes. Growing and
 +
dying dendritic spine activations act as a constraint storage
 +
medium. Heavy use erodes constraints, and light use restores
 +
erosions, allowing manifold migrations to adapt to experience.
 +
Manifold repulsion is controlled. Where fully active, the manifold
 +
field is conservative and making associations and decisions are
 +
logical. Where partially active, associations and decisions need
 +
not be logical.
-
I respect the cleverness of AI, neural nets, neuromorphic engineering, HTM, quantum computing, and all that; but all I see when I review the anatomy, histology, physiology, and in-vivo experiments is a mathematics of reflex and nothing more.
+
This is the basis of neural implementation of reflex.
 +
The rules appear to apply across the animal kingdom. Model
 +
neurons are useful for assembly into synthetic reflex systems.

If nothing else, I am having immense fun.

I abhor the stern look over the lorgnette and worse used to cause disquiet in the bosoms of those who pique interest through variation, whether by choice or chance.

  • The brain is made of matter. Matter is subject to the laws of physics.
  • Newtonian mechanics is sufficient.
  • Operations appear to be properties of material arrangements.
  • Knowledge of signals and systems is useful.

If it seems not obvious how to make a brain, it is because the patterns by which the laws of physics are employed to make a brain have not been published and turned into laws of brain physics.

Only this and nothing more. (Edgar Allen Poe)

  • A robot can have a synthetic brain made of different material than an animal brain.
  • The complexity of that synthetic brain is unbounded.
  • There is nothing to impede that except the lack of knowledge about what makes a brain a brain.
