Altered Kinematic Patterns and Synapses in Recovery of Motor Behavior After Hindlimb Deafferentation in Cats

摘要: Recovery of motor behavior following damage to the adult mammalian CNS could occur in a number different ways. One possibility is that initially lost or impaired physiological mechanisms underlying normal are restored due plasticity remaining systems. For example, when pathway system only partially damaged, spared parts may increase control they exert. way which this might if cells post-synaptic their responsiveness reduced input by changes regulation receptors increases sprouting. The prediction follows from model immediately lesion and recovers at later time will be similar many respects. Another recover involves production movement which, because conditions imposed injury, differ ones. This mode recovery anticipated an entire has been eliminated. In case, does indeed recover, mechanisms, no longer available, must replaced others. Since anatomical pathways mediating relevant functions then some extent ones, it seems reasonable expect alterations as well.
