tDCS (Transcranial Direct Current Stimulation) is a contemporary form of neurostimulation
(or neuromodulation) that delivers a constant low current to specific areas of the brain.
How does it work exactly? By applying a positive or negative current through electrodes to one area to help with the depolarization or hyperpolarization of neurons, in other words, increasing or lowering neurons’ threshold to send electrical pulses.
Originally, tDCS was developed and refined to aid patients with brain injuries or with neurological disorders, however, several scientific studies have demonstrated the effectiveness of tDCS in cognitive enhancement for the general population.
According to Google Trends, Denmark, USA, and Australia are the top three countries using tDCS, today. Denmark has admitted tDCS to public, private, and education hospitals, Australia has promoted tDCS as a non-invasive treatment, and the USA has validated tDCS technology on a large scale.
In this cozy safe space of mine, I rank the best tDCS devices of 2020:
The Fisher Wallace Stimulator Starstim R32, Caputron Activadose II (scroll down for a special discount code)
The Brain Stimulator v3.0 and the ApeX Type A. based on their features, cost, delivery time, and effectiveness.
