Operational dynamical primitives

• The NS will, in turn, have to be coupled to the global metabolic needs of the organism.

• But the hierarchical decoupling will allows us to specify the operational primitives (dynamical variables) that constitute this domain, mainly:

  • change of membrane action potential over time (spikes),
  • synaptic connections (connectivity matrix) and
  • modulators: synaptic (local and global) and threshold.

• The research for this dynamical primitives and its functional higher level organization constitutes the search for a neural “code”: what kind of local differences can make a global difference (spikes, rates, gas-nets, etc.).
