Action Potential01:31

Action Potential

7.6K
Neurons communicate by firing action potentials—the electrochemical signal that is propagated along the axon. The signal results in the release of neurotransmitters at axon terminals, thereby transmitting information to the nervous system. An action potential is a specific "all-or-none" change in membrane potential that results in a rapid spike in voltage.
Membrane potential in neurons
Neurons typically have a resting membrane potential of about -70 millivolts (mV). When they...

概括

无周期电脑电图 (EEG) 活动,特别是无周期指数,可能表明代码冲突. 较低的指数表明神经噪声增加和在相互冲突的刺激时决策受损.

科学领域:

  • 认知神经科学 认知神经科学
  • 计算神经科学是一种神经科学.

背景情况:

  • 代码冲突是由重叠的刺激和响应特征引起的.
  • 事件文件理论表明,组合的特征被存储和检索.
  • 周期性脑电图 (EEG) 反映了神经活动的动态.

研究的目的:

  • 调查无周期性EEG活动与代码冲突之间的关系.
  • 为了确定非周期性EEG是否可以作为代码冲突的神经标记.
