Mapping the Mechanisms of Transcranial Alternating Current Stimulation: A Pathway from Network Effects to Cognition

Modafinil for cognitive neuroenhancement in healthy non-sleep-deprived subjects: A systematic review

“…However, it is noteworthy that with more protracted and complex testing, more benefits are being associated with modafinil use rather than less, which suggests that modafinil may well deserve the title of the first well-validated pharmaceutical 'nootropic' agent. This observation is also true of non-invasive brain stimulation techniques, in which more integrative cognitive assessments and physiological recordings are yielding increasingly valuable insights into the mechanisms by which they may engender cognitive enhancement (see, for example, Battleday et al, 2014;Santarnecchi et al, 2015). In this vein, we hope our recommendations for future study will assist in advancing and consolidating the cognitive investigation of neuroenhancement agents, and, in doing so, contribute valuable information to wider discourse on the achievability and role of neuroenhancement within wider society.…”

Spatial Attention and the Effects of Frontoparietal Alpha Band Stimulation

“…It has been proposed that tACS modulates cognitive function via a combination of neural entrainment and resonance, which results in the recruitment of neurons into a local oscillating network that in turn affects both local and network level computations (Battleday et al, 2014). Previous studies have applied tACS in the alpha frequency to parietal/occipital cortex.…”

Modulating reconsolidation: a link to causal systems-level dynamics of human memories

“…tACS is a promising technique by which an alternating current may entrain in a frequency-specific fashion the underlying oscillatory activity in cortical networks [92]. In addition to rhythmic rTMS [93], tACS offers the opportunity to causally link brain oscillations in a specific frequency range to cognitive processes [92].…”
