Summary
Enhancing slow-wave activity (SWA) during sleep may improve cognitive function. This review explores SWA enhancement pathways and techniques, evaluating their potential for cognitive benefits.
Area of Science:
- Neuroscience
- Sleep Science
- Cognitive Science
Background:
- Slow-wave activity (SWA) is crucial for cortical plasticity and cognitive function.
- The relationship between SWA and cognition suggests potential for cognitive enhancement through SWA manipulation.
- Current SWA enhancement techniques vary in feasibility and specificity.
Purpose of the Study:
- To review pathways for enhancing slow-wave activity (SWA).
- To evaluate the robustness and practicality of different SWA enhancement techniques.
- To discuss methods for establishing a causal link between SWA and cognitive improvements.
Main Methods:
- Literature review of SWA enhancement pathways and techniques.
- Analysis of behavioral and laboratory-based interventions.
- Evaluation of methods for assessing SWA's causal role in cognition.
Main Results:
- SWA enhancement can be achieved through mechanisms during wakefulness (neural activity, metabolism, endocrine signaling) and directly during sleep.
- Techniques range from feasible but non-specific (exercise) to specific but less feasible (transcranial stimulation).
Conclusions:
- SWA enhancement presents a promising avenue for cognitive improvement.
- Further research is needed to clarify SWA-dependent cognitive mechanisms and optimize enhancement strategies.

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

02:05Gene Evolution - Fast or Slow?
8.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.

The simplest mechanical waves are associated with simple harmonic motion and repeat themselves for several cycles. These simple harmonic waves can be modeled using a combination of sine and cosine functions. Consider a simplified surface water wave that moves across the water's surface. Unlike complex ocean waves, in surface water waves, water moves vertically, oscillating up and down, whereas the disturbance of the wave moves horizontally through the medium. If a seagull is floating on the...
