A protocol for memory enhancement by using transcranial direct current stimulation (tDCS) targeting dorsolateral prefrontal and posterior parietal cortices, as core cortical nodes within hippocampo-cortical network, is presented. The protocol has been well evaluated in healthy-participant studies and is applicable to aging and dementia research as well.

The paper is primarily focused on the combined power of optical (linear and nonlinear) and holographic methods used to reveal phenomena at the nanoscale. The results obtained from the biophotonic and oscillatory chemical reactions' studies are given as representative examples, highlighting holography's ability to reveal dynamics at a nanoscale.
