关键时期是大脑可塑性显著的时期。在视觉皮层出生后发育的关键时期,一只眼睛的闭塞触发了神经元反应的快速重组,这一过程被称为眼优势可塑性。我们已经证明,移植抑制性神经元诱导眼优势可塑性的关键期后。移植的抑制性神经元接受兴奋性突触,使抑制性突触宿主皮层神经元,并促进可塑性时,他们达到一个细胞年龄相当于内源性抑制性神经元在正常的关键期。这些研究结果表明,眼优势可塑性是由抑制性神经元固有的成熟程序的执行。通过诱导可塑性,抑制性神经元移植可能促进脑修复。
Critical periods are times of pronounced brain plasticity. During a critical period in the postnatal development of the visual cortex, the occlusion of one eye triggers a rapid reorganization of neuronal responses, a process known as ocular dominance plasticity. We have shown that the transplantation of inhibitory neurons induces ocular dominance plasticity after the critical period. Transplanted inhibitory neurons receive excitatory synapses, make inhibitory synapses onto host cortical neurons, and promote plasticity when they reach a cellular age equivalent to that of endogenous inhibitory neurons during the normal critical period. These findings suggest that ocular dominance plasticity is regulated by the execution of a maturational program intrinsic to inhibitory neurons. By inducing plasticity, inhibitory neuron transplantation may facilitate brain repair.
