[Simulation of neuronal networks (SIRENE). II. Hypothesis for decoding the message of movement carried by spindle afferences IA and II by a mechanism of synaptic plasticity].

The spindle message derived from passively stretched muscles during a movement, carries mixed information about the velocity and the position of the joint concerned. With the help of the program SIRENE, it is shown that a non-specialized neuron can decode this message, and it is able especially to extract from the mixture the pure velocity component, and that under a weak assumption on synaptic plasticity.
