全对全耦合神经元中的触发状态

Triggering up states in all-to-all coupled neurons

Hong-Viet V. Ngo, Jan Köhler, Jörg Mayer, Jens Christian Claussen, Heinz Georg Schuster

摘要:

慢波睡眠的特点是大规模的皮质活动的变化,目前被解释为皮质上/下状态。最近的一个实验证明了雪貂切片的集体行为,具有显着的特性,即Up状态可以用相同极性的脉冲或激励来打开和关闭;其中第二个脉冲的效果显着取决于脉冲之间的时间间隔。在这里,我们提出了一个简单的时间离散模型的神经网络,表现出这种类型的行为,以及定量再现实验中发现的时间依赖性。

英文摘要:

Slow-wave sleep in mammalians is characterized by a change of large-scale cortical activity currently paraphrased as cortical Up/Down states. A recent experiment demonstrated a bistable collective behaviour in ferret slices, with the remarkable property that the Up states can be switched on and off with pulses, or excitations, of same polarity; whereby the effect of the second pulse significantly depends on the time interval between the pulses. Here we present a simple time discrete model of a neural network that exhibits this type of behaviour, as well as quantitatively reproduces the time-dependence found in the experiments.
