The "involuntary postcontraction" mechanism or the postcontractile elastic restitution.
Unquestionable experimental proofs are brought forward in support of the non-cortical origin of "involuntary postcontraction". The mechanism of this phenomenon is purely passive and it originates in the elastic component of the muscular organ. Far from inducing the postcontractile event, cortical induction brakes it. The results obtained up to now enable the authors to consider that the analysis of postcontraction provides quantifiable information of great practical importance on the type and momental functional state of human nervous system.
