Neocortical slow waves are critical for memory consolidation. The retrosplenial cortex is thought to facilitate the slow wave propagation to regions beyond the neocortex. However, it remains unclear which population is responsible for the slow wave propagation. To address this issue, we performed in vivo whole-cell recordings to identify neurons that were synchronous and asynchronous with slow waves. By quantifying their intrinsic membrane properties, we observed that the former exhibited regular spiking, whereas the latter exhibited late spiking. Thus, these two cell types transmit information in different directions between the neocortex and the hippocampus.

麻醉小鼠的后尖峰压后皮质神经元与新皮质慢波不同步

新皮质慢波对于记忆巩固至关重要。压后皮质被认为有助于慢波传播到新皮质以外的区域。然而，目前尚不清楚哪些人群造成了慢波传播。为了解决这个问题，我们进行了体内全细胞记录，以识别与慢波同步和异步的神经元。通过量化它们的内在膜特性，我们观察到前者表现出规则的尖峰，而后者表现出较晚的尖峰。因此，这两种细胞类型在新皮质和海马体之间以不同方向传递信息。
