Rectification The conversion of alternating current (AC) to direct current (DC) This involves a device that only allows one-way flow of electrons semiconductor diode Half-wave Rectification allows one half of an AC waveform to pass through to the load Full-wave Rectification Full use of both ha...
Transcranial alternating current stimulation (tACS), which works by applying alternating current of low intensity through the scalp to the brain, is one of the so-called non-invasive brain stimulation methods (NIBS). The current intensity is too small to induce action potential by itself, however,...
Transcranial alternating current stimulation(tACS) is relatively a newly developed stimulation technique that non-invasively modulatescortical excitabilityand activity. WhiletDCSinducesneuroplasticityvia the constant polarization ofneuronal membranepotentials with the application of a tonic subthreshold direct current...
which were antiphase with the return current at Cz (blue pad). tACS at PFC and TPJ has an amplitude of 1 mA (zero-to-peak), while the return current at Cz has an amplitude of 2 mA (zero-to-peak)
Transcranial Direct Current Stimulation for the Treatment of Hallucinations in Patients with Schizophrenia Introduction Alterations in brain oscillations and the temporal coordination of neural activity between brain regions have been associated with a wide range of psychiatric disorders1. Rhythmic brain stimula...
We explain this surprising interaction between manipulability and memory as being mediated by automatic vs. controlled motor-related cognition. (C) 2012 Elsevier Inc. All rights reserved.doi:10.1016/j.ijpsycho.2012.06.019Struber, D.Rach, S.
Cooperation can be maintained by direct reciprocity, where individuals help others in repeated interactions1,2,3. Traditionally, researchers capture the logic of direct reciprocity with the repeated prisoner’s dilemma4,5,6,7,8,9,10,11,12,13,14,15,16,17. According to that model, two individu...
Other research applying bi-frontal transcranial direct current stimulation (tDCS) to modulate Total Sleep Time (TST) and sleep efficiency, found that these were reduced after verum tDCS relative to control [13]. Another study [14] found that bilateral open-loop transcranial alternating current ...

It examines personal truths about the direct experiences of those who do not get on the news or attend UFO conventions, and how this can tell us more about these encounters on an individual level, where I believe the best understanding of this mystery lies. It also stands as a snapshot ...
