神经发生是发生在成人大脑有限区域的结构和功能重塑的强大机制。虽然不同的神经递质调节从神经干细胞静止到神经元成熟的各个方面,但GABA是主要参与者。从兴奋到抑制的发育转换,以及针对不同亚细胞室的GABA能中间神经元的异质性群体,为新神经元的发育和功能调节提供了多个点。反馈和前馈网络作为电路活动的传感器和控制器,直接或间接地作用于发育中的颗粒细胞,并随后影响成熟神经元,从而增强了这种复杂性。新产生的颗粒细胞最终以一种在很大程度上由局部电路的活动塑造的方式与输入和输出伙伴连接。
Neurogenesis is a powerful mechanism for structural and functional remodeling that occurs in restricted areas of the adult brain. While different neurotransmitters regulate various aspects of the progression from neural stem cell quiescence to neuronal maturation, GABA is the main player. The developmental switch from excitation to inhibition combined with a heterogeneous population of GABAergic interneurons that target different subcellular compartments provide multiple points for the regulation of development and function of new neurons. This complexity is enhanced by feedback and feedforward networks that act as sensors and controllers of circuit activity, impinging directly or indirectly onto developing granule cells and, subsequently, on mature neurons. Newly generated granule cells ultimately connect with input and output partners in a manner that is largely sculpted by the activity of local circuits.
