Auditory network persistence of stimulus representation in awake and naturally sleeping mice Open
Persistent neural activity often outlasts sensory stimulation, bridging perception and action. While commonly linked to working memory and decision making, its existence during passive states and sleep remains unclear. Using chronic high-d…

Abrupt and gradual changes in neuronal processing upon falling asleep and awakening Open
The neural processes that change when falling asleep are only partially understood. At the cortical level, features of both spontaneous neural activity and sensory responses change between wakefulness and sleep. For example, in early audit…
