Controlled and uncontrolled stimulation of the motor activity of 18-day chick embryo induces ultrastructural changes in sensomotor region of the archistriatum. These changes include the increase in the bulk of membrane structures, the increase of the area of presynaptic regions, the increase in electron density of microtubules and neurofilaments. Formation of a new adaptive behaviour is accompanied by an increase in the number of active synapses, which presumably accounts for adaptive plasticity of the brain in embryogenesis.
对18日龄鸡胚运动活动进行控制性和非控制性刺激，会诱导旧纹状体感觉运动区域发生超微结构变化。这些变化包括膜结构总量增加、突触前区域面积增大、微管和神经丝电子密度增加。新适应性行为的形成伴随着活跃突触数量的增加，这可能是胚胎发育过程中大脑适应性可塑性的原因。
