Comparative Study of the Frontal EGG Activity After Superficial Neuro-stimulation Application, Mindfulness and Other Attentional Techniques

Abstract

Introduction

Changes in the electrical cerebral activity, especially in frontotemporal regions, have been described after using the Superficial Neurostimulation Application (SNSA) in upper and lower limbs. The use of this technique is associated with emotional equilibrium and predisposition for a positive mood. Its application clinically improves hostility and anxiety symptoms.

Aims

To compare the electrical changes observed after the use of SNSA with other techniques of mental concentration: Mindfulness (mental attention without judgment) and a technique based on the emission of a sound.

Materials and methods

SNSA topology system: uses electricity through superficial electrodes placed on feet and hands and an electrode over the 7th cervical vertebra; Digital encephalogram; Faraday cage.

Results

Mindfulness and SNSA techniques show similarities regarding the alpha rhythm's frequency in frontal regions (Figs. 1 and 2) compared to a different mental concentration technique (Fig. 3).

Conclusion

Further analysis would be required.
