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:
- gross architecture is that there are input nuclei, cerebellar cortex, and output nuclei
- there are climbing fibers and mossy fibers going from input nuclei to cerebellar cortex
- input nuclei are divided into mossy nuclei, which are source of mossy fibers and climbing nuclei which are source of climbing fibers
- cerebellar cortex has the same implementation for all surface and contains of output cells - GABA purkinje neurons which are aligned with processing streams, and granular cells
- climbing fibers are the same for vermal, paravermal, lateral layers - each IO neuron has projections to 3 purkinje cells, one per each layer
