Abstract

Both ongoing and natural stimulus driven neuronal activity are dominated by transients. Selective gating of these transients is mandatory for proper brain function and may, in fact, form the basis of millisecond-fast decision making and action selection. Here we propose that neuronal networks may exploit timing differences between correlated excitation and inhibition (temporal gating) to control the propagation of spiking activity transients. When combined with excitation-inhibition balance, temporal gating constitutes a powerful mechanism to control the propagation of mixtures of transient and tonic neural activity components.

摘要

持续的和自然刺激驱动的神经元活动都以瞬态为主。这些瞬态的选择性门控对于正常的大脑功能是必需的,实际上可能构成了毫秒级快速决策和动作选择的基础。在这里,我们提出神经元网络可能利用相关兴奋和抑制之间的时间差(时间门控)来控制尖峰活动瞬态的传播。当与兴奋-抑制平衡结合时,时间门控构成了控制瞬态和紧张性神经活动成分混合物传播的强大机制。
