The mechanisms supporting hippocampal memory reactivation are puzzling. Reactivation occurs during ripple oscillations, yet ripples are not coordinated across regions. In this issue of Neuron, Carr et al. (2012) report that another oscillation, slow gamma, coordinates memory reactivation across the hippocampal network.
支持海马体记忆再激活的机制令人费解。再激活发生在涟漪震荡期间,但涟漪震荡在区域之间没有协调。在本期《神经元》杂志上,Carr 等人(2012)报告称,另一种震荡——慢伽马波——协调了海马体网络中的记忆再激活。
