This page covers biological coordination approach of specific circuts and complexes.

Overview

Major biological circuits are:

• cerebellar control

Cerebellar Control

Further explanation is genuine outcome of aHuman research (C) and is not repsesented elsewhere. Please mention origin if copy.

essence of architecture:

• first major feature is that cerebellar complex produces information about which muscle executions are wrong and need to be inhibited
  • it stores actual muscle execution patterns associated with certain layer of execution, many-to-many (all muscles to all layer streams)
  • it inhibits corresponding layer of execution in streams related to items, not belonging to stored patterns
  • conscious execution causes cerebellum to learn patterns, automatic execution leads to using stored patterns
• second major feature is that cerebellum performs coordinate system translation
  • vermis from eyes and head coords into muscle coords
  • paravermis - from somatic coords to muscle coords
  • lateral lobe - from intention coords (frontopontine - M1/S1), absolute coords (parietopontine - IPL/SPL), visual feature coords (occipitopontine - V2) to muscle coords
  • flocculonodular lobe - from earth coords to oculomotor muscle coords

layers of execution are:

• subcortical execution of flexors by somatic patterns - paravermal lobe
• cortical execution of flexors by cortical patterns - lateral lobe
• execution of limb extensors by superior colliculus patterns - vermal lobe
• execution of trunk extensors by vestibular patterns - flocculonodular lobe

implementation:

• climbing fibers are the same for all layers - each IO neuron has projections to 3 purkinje cells, one per each layer
