研究人员发现,在thalamic网状核 (TRN) 神经元中协调突发发射可以削弱电突触. 这种依赖于使用的可塑性,特定于神经活动的方向,表明了动态网络重组的机制.
科学领域:
- 神经科学是一个神经科学.
- 突触性可塑性 突触性可塑性
- 神经网络的神经网络的神经网络
背景情况:
- 在化学突触中,使用依赖的突触可塑性是众所周知的.
- 自然活动在调节电突触强度中的作用在很大程度上是未知的.
- 乳头网状核 (TRN) 使用电突触,对注意力和兴奋状态至关重要.
研究的目的:
- 研究TRN内的电突突触的活动依赖性可塑性.
- 为了确定协调的神经元发射是否会影响间隙结沟通的强度.
主要方法:
- 来自配对的TRN神经元对的电生理学记录.
- 诱导协调的爆发发射模式.
- 测量沟通强度的变化. 沟通强度的变化.
主要成果:
- 协调爆发引发长期压缩 (LTD) 在电突触.
- 观察到的沟通沟通的变化是不对称的.
- 突触修饰取决于神经元活动的方向.
结论:
- 电突触的活动依赖性修改是一种可行的机制.
- 不对称的可塑性表明神经网络连接的方向依赖调节.
- 这种可塑性可能是TRN和其他电气联网络的动态网络重组的基础.

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
