Attempts to enhance human memory and learning ability have a long tradition in science.
This topic has recently gained substantial attention because of the increasing percentage of …

Older adults do not sleep as well as younger adults. Why? What alterations in sleep quantity
and quality occur as we age, and are there functional consequences? What are the …

Computational modeling and human studies suggest that transcranial alternating current
stimulation (tACS) modulates alpha oscillations by entrainment. Yet, a direct examination of …

In the human brain, oscillations occur during neural processes that are relevant for memory.
This has been demonstrated by a plethora of studies relating memory processes to specific …

In recent decades, increasing evidence has positioned slow-wave sleep (SWS) as a major
actor in neurophysiological phenomena such as glucose metabolism, hormone release …

Sleep disruption appears to be a core component of Alzheimer's disease (AD) and its
pathophysiology. Signature abnormalities of sleep emerge before clinical onset of AD …

Alzheimer9s disease (AD) not only involves loss of memory functions, but also prominent
deterioration of sleep physiology, which is already evident at the stage of mild cognitive …

Precise temporal coordination of slow oscillations (SO) and sleep spindles is a fundamental
mechanism of sleep-dependent memory consolidation. SO and spindle morphology …

Transcranial electrical stimulation has widespread clinical and research applications, yet its
effect on ongoing neural activity in humans is not well established. Previous reports argue …

A number of rhythmic protocols have emerged for non-invasive brain stimulation (NIBS) in
humans, including transcranial alternating current stimulation (tACS), oscillatory transcranial …
