Neuroscience Dendrites occupy more than 90% of neuronal tissue. However, it has not been possible to measure distal dendritic membrane potential and spiking in vivo over a long period of time. Moore et al. developed a technique to record the subthreshold membrane potential and spikes from neocortical distal dendrites in freely behaving animals. These recordings were very stable, providing data from a single dendrite for up to 4 days. Unexpectedly, distal dendrites generated action potentials whose firing rate was nearly five times greater than at the cell body. Science , this issue p.

树突比预期的更活跃

神经科学 树突占神经元组织的 90% 以上。然而，在很长一段时间内无法在体内测量远端树突膜电位和尖峰。摩尔等人。开发了一种技术来记录自由行为动物的新皮质远端树突的亚阈值膜电位和尖峰。这些记录非常稳定，提供来自单个树突的数据长达 4 天。出乎意料的是，远端树突产生的动作电位的放电率几乎是细胞体的五倍。科学，这个问题 p。[eaaj1497][1][1]：/lookup/doi/10.1126/science.aaj1497
