Topic: cortical sleep spindles

A hallmark of Alzheimer’s disease (AD) pathology is amyloid plaques which can lead to neuroinflammation, cellular dysfunctions as well as altered neuronal activity. Both AD patients and mouse models exhibit abnormal neural oscillations, including altered gamma oscillations, hippocampal sharp wave-ripples (SWRs) and cortical sleep spindles. Although these oscillations play a role in memory formation and consolidation, it remains poorly understood how abnormal oscillations relate to novel experiences. Here we show that deficits in SWRs are experience-dependent in an AD mouse model. We performed
