Physics of the Brain. Treatment of Neurological Diseases via the Excitation-Suppression of the Brain Waves, Using the Multi-photon Pulsed-operated Fiber Lasers in the Ultraviolet Range of Frequencies with Modulated Repetition Frequency

The novel study of the brain waves (BW)\footnote{ Tae Kim et. al. Cortically projecting basal forebrain parvalbumin neurons regulate cortical gamma band oscillations, Proceedings of the National Academy of Sciences, vol. 112 no. 11, 3535--3540, (2015).} in connection to neurological diseases is proposed. It is based on the pulsed-operated (amplitude modulation) multi-photon (frequency modulation) fiber-laser interaction with the brain neuro-topion (the neurological disease area)\footnote{ Stefan, APS-March 2020, {\#} M71.00361;Stefan et al.,Bull.

The modulated repetition frequency, $\Omega $, (5-100 pulses per second) enables a fine-tuning with the brain waves, $\Omega_{\mathrm{BW\thinspace }}$. The tunable fiber laser frequencies are in the ultraviolet frequency range, thus enabling monitoring of the electrical charge dynamics in the neuro-topion of a particular neuro-disease within the 10s of milliseconds.
