Summary: Suppose the cortex is a 'representation' of the environment, i.e. corresponding to
events in the periphery (stimuli, reactions) there are events in the cortex. Nothing
new in this idea. But suppose that the cortex is more 'sensitive', so that if the
periphery is being driven out of its range of stability the corresponding variable
in the cortex will break first, i.e. get outside its range of stability, and thus switch to another portion of the
field (817), and change partially to another organisation. Cortex as 'sensitive' Reactions right and wrong Reflex, conditioned
Summary: The lower animals, at any rate, with their environment may be much simplified for
our purpose by noting that one animal may be considered to be split into several,
or many, parts, each of which has its own environment. So animal and environment = several machines, not one. Dominance and velocity Equilibrium of organisations Independence and velocity Levels mechanism of Organisation stable
Summary: We have discussed the situation: p's dominate x's, and x's dominate y's. Under these conditions we can get a stability of organisation. Also we can get y-point in y-space moving twice through the same point in different directions. If the x's react rapidly they will tend to disappear functionally. A succession of such gives
transmission through a series of organisations. If one level has only a few, or a
single, variable this introduces an essential simplicity into all subsequent levels.
A large organisation may be 'simple' because it depends on only one or a few parameters. Equilibrium of organisations Organisation exploring organisation
Summary: The idea that "orderliness" or "intelligence" spreads like crystallisation is probably
covered more correctly by the more precise idea that it is "reaching neutral point
and stopping still" which spreads along a chain of dominance. Break equations for Dominance chain of Equilibrium spread of Organisation spread of Step function in differential equations
Summary: "Equilibrium" means not moving out of a given region. (But see 1143)
Summary: It might be suggested that with a million neurons the chance of getting them all properly
adjusted is negligibly small. The answer is that there is usually no such thing as
the right solution. We count as suitable any organisation whatsoever so long as it gets
the equilibrium where we want it. Organisation no "right"
Summary: After studying the fixed points in a dynamic world (i.e. neutral points) I presume
the next step would be to take a lot of neutral points and set them moving. Equilibrium change of
Summary: The definition of "equilibrium" is taken up from 1092, and made much more precise. It is concluded that it belongs to a path A special type of common occurrence is defined and given the name of "normal" equilibrium. Equilibrium "normal" Equilibrium essential definition
Summary: All my theory explains the "trial and error" method in terms of non-living matter.
All that, but nothing more. Equilibrium Courant's definition
Summary: Courant's definition of equilibrium. On closer reading, as R and ρ may be small to any degree, it appears that Courant's definition does not allow finite cycles like that of 1144.
Summary: Multistable system gives partly additive responses. A reaction pattern can be 'strengthened'
by noisy variation of parameters. 4155 Noisemay improve multistable systems The Multistable System : The deliberate injection of noise into a multistable system may improve its performance
in some specific learning. 3019.
Summary: The whole built from random parts, by random coupling, when each part has probability
πi that its state is equilibrial, does not go (if not in equilibrium) equiprobably to
all states but favours those "near" itself. Summary 5524 Metric Hockett's metric
Summary: Parts that have only one state of equilibrium (for each given input) may build a whole
with a multiplicity of equilibria. Equilibrium number possible in whole Organisation number of equilibria
Summary: Wiener suggests that maths is a dynamic process, that may end in a cycle. Proof nature of
Summary: A proposition is "atomic" if its user does not propose to break it up. Summary: The brain may be like a digital computer in being error-free by going from equilibrium
to equilibrium. 6126 Equilibrium give error-free action
Summary: We study "machines" that depend on their immediately preceding states because experience
has shown them to be very common in the world around us. 6246 Equilibrium complement of ergodicity Ergodism complement of equilibrium
Summary: I must write a text book on the Theory of Equilibrium. 6350
Summary: Sketch of a theory that two coupled systems, in going to equilibrium, tend to prefer
regions in their phase-spaces that are topologically similar. Equilibrium when topologies match
Summary: At equilibrium, with suitable metric, the responses have a bias towards smallness.
