尖峰可以传递神经元的阈下膜电位

Spikes can transmit neurons' subthreshold membrane potentials

Valentin Schmutz

AI总结:

本文从理论上证明,尽管神经元通过跨越阈值的尖峰通信,其阈下膜电位波动仍可被完美传递至下游群体,这是高维集中现象的体现。

摘要:

神经元主要通过发放动作电位(即尖峰)进行通信。要产生一个尖峰,神经元的膜电位必须跨越一个确定的阈值。这种尖峰机制是否本质上阻止了神经元将其阈下膜电位波动传递给其他神经元?我们从理论上证明,它并不会。一个发放尖峰的突触前神经元群体的阈下膜电位波动可以被完美地传递给下游的神经元群体。在数学上,这一令人惊讶的结果是高维空间中集中现象的一个例子。

英文摘要:

Neurons primarily communicate through the emission of action potentials, or spikes. To generate a spike, a neuron's membrane potential must cross a defined threshold. Does this spiking mechanism inherently prevent neurons from transmitting their subthreshold membrane potential fluctuations to other neurons? We prove that, in theory, it does not. The subthreshold membrane potential fluctuations of a presynaptic population of spiking neurons can be perfectly transmitted to a downstream population of neurons. Mathematically, this surprising result is an example of concentration phenomenon in high dimensions.
