The presence of ineffective synapses and the circumstances which unmask them.

摘要: In this paper, we shall show that there are substantial numbers of nerve terminals which normally ineffective. the intact animal, occasional signs postsynaptic effectiveness these fibres can be seen under conditions optimal spatial summation or increased excitability decreased inhibition. If functioning afferent blocked cut, some previously ineffective immediately establish an effective drive cells. normal afferents cut and allowed to degenerate, large cells begin respond new inputs. The presence synapses in adult offers alternative sprouting opening up polysynaptic pathways as a possible mechanism explain plasticity connections brains.
