前额叶皮层(PFC)是一种参与认知和情感领域各种复杂功能的皮层结构。PFC的内在功能是由局部多巴胺能和GABA能神经元的相互作用以及它们受长程输入的调制来定义的。随后的相互作用在每个输出神经元中产生了兴奋和抑制(E-I)的比例,这是在青少年向成人过渡期间得到改善的平衡。在这篇简短的综述中,我们的目的是描述青春期GABA能传输的增加如何改变成人的E-I比率。我们进一步讨论了这个新的设定点可能会改变动态PFC网络在过渡到成年。
The prefrontal cortex (PFC) is a cortical structure involved in a variety of complex functions in the cognitive and affective domains. The intrinsic function of the PFC is defined by the interaction of local glutamatergic and GABAergic neurons and their modulation by long-range inputs. The ensuing interactions generate a ratio of excitation and inhibition (E-I) in each output neuron, a balance which is refined during the adolescent to adult transition. In this short review, we aim to describe how an increase in GABAergic transmission during adolescence modifies the E-I ratio in adults. We further discuss how this new setpoint may change the dynamics of PFC networks observed during the transition to adulthood.
