抑制性神经元异质性引起的最佳反应性和集体振荡

Optimal responsiveness and collective oscillations emerging from the heterogeneity of inhibitory neurons

Matteo di Volo, Alain Destexhe

摘要:

大脑的特点是抑制性神经元的高度异质性。我们报告说,尖峰神经网络显示的抑制性神经元的异质性的共振,与最佳的输入/输出响应发生的异质性水平相似的实验发现在大脑皮层。一个异质平均场模型预测这样的最佳响应。此外,我们表明,新的动力学制度出现的异质性,不存在于等价的均匀系统,如稀疏同步集体振荡。

英文摘要:

The brain is characterized by a strong heterogeneity of inhibitory neurons. We report that spiking neural networks display a resonance to the heterogeneity of inhibitory neurons, with optimal input/output responsiveness occurring for levels of heterogeneity similar to that found experimentally in cerebral cortex. A heterogeneous mean-field model predicts such optimal responsiveness. Moreover, we show that new dynamical regimes emerge from heterogeneity that were not present in the equivalent homogeneous system, such as sparsely synchronous collective oscillations.
