Thalamus

Drivers and modulators

Driver inputs to the thalamus, whether cortical or subcortical, tend to be "efference copies" -- the axons providing the input branch off and the other brnach also goes to some subcortical motor or premotor structure.

possible low-level functions

signal propagation

prediction

function approximation

anti-correlation

clustering

dimensionality reduction

universal turing machine

regexp

FSM

routing

memory (map)

memory (autoassociative)

pointwise arithmetic: +, -, *, /

convolutions

reinforcement learning

planning

NP-complete solving

optimization

CPG (rhythmic output)

fourier/wavelet transform

multiplexing

selective signal amplification tune into one frequency

recirculate information for awhile (circuit-level short term memory)

locks/semaphores

boolean logic gates

(database) transactions

addressing models: linear none tree

some peculiarly cognitive ones:

imitation

analogical reasoning

modeling self (i.e. introspection)

object recognition

"workspace model of consciousness" (i.e. broadcast)

coding regimes (single neurons):

rate coding "spike" coding phase coding AM FM

coding regimes (ensemble):

linear "sparse" hash

possible objectives being optimized:

minimize: wiring length energy MSE transmission time or computation time

maximize: information ML predictions/reward (?) MAP predictions/reward (?) precision/resolution number of patterns stored in memory S/R ratio
