Abstract

The invention discloses a method for improving attention breadth through transcranial direct current stimulation and a device thereof, and the method comprises the following steps: randomly presentingcharacter strings with a plurality of lengths in a specified region of a screen; when a testee judges the length of the character string, recording the response time and the answer correctness of each question of the testee, collecting a testee electroencephalogram signal so as to test the response time and evaluate the score, and evaluating the activation condition of the brain during the attention breadth experiment through the electroencephalogram signal; employing an electrical stimulator, using a tDCS anode electrode for stimulating the dorsal-lateral forehead cortex on one side, and meanwhile placing a tDCS cathode electrode on the other side. According to the method, the attention breadth can be effectively improved, the improvement effect can be evaluated, and the method is simpleand easy to implement.

Description

technical field [0001] The invention relates to the technical field of cognition improvement, in particular to a method and device for improving attention span through transcranial direct current stimulation. Background technique [0002] Transcranial direct current stimulation (tDCS) is a non-invasive means of modulating neural activity. By applying a weak current to the scalp, the cortical excitability in the area stimulated by anodal electrodes is increased, and the excitability of the cortex in the area stimulated by cathodal electrodes is decreased. Because the strength and duration of cortical excitation or inhibition by tDCS can be effectively controlled by adjusting the current intensity and stimulation application time, its safety has been confirmed. [0003] In 2005, Fregni et al launched a study on the impact of tDCS on cognitive ability. They placed anodal tDCS electrodes in the left dlPFC area to activate the cortex, and successfully verified that tDCS has a si...
