a novel approach for documenting phosphenes induced by transcranial magnetic stimulation

인간의 시각 피질의 자극은 phosphene로 알려진 빛의 과도 인식을 생산하고 있습니다. Phosphenes은 후두 피질의 침입 전기적 자극에 의​​해 유도뿐만 아니라 비침습 Transcranial 자석 자극 (TMS)에서 아르<sup&gt; 1</sup&gt; 같은 대뇌 피질의 영역. phosphene가 유도하는에있는 강도 (phosphene 임계값) 시각 피질 흥분의 잘 설립 측정하고 cortico - 대뇌 피질의 상호 작용, 기능 조직을 연구하는 데 사용됩니다<sup&gt; 2</sup병리학에&gt;, 자화율<sup&gt; 3,4</sup&gt; 및 영상 처리<sup&gt; 5-7</sup&gt;. 제목의 눈을 뜨고거나 닫힐 때 그들은 유도하며, 시선의 방향과 자신의 공간적 위치 변화, 그들은 자극에 contralateral 시각 hemifield에서 관찰됩니다 Phosphenes는 일반적으로 세 특성에 의해 정의됩니다<sup&gt; 2</sup&gt;. 다양한 방법 phosphenes을 문서화하는 데 사용되고 있지만, 표준화된 방법론이 부족합니다. 우리는 phosphene 문턱 값을 구하여 phosphenes의 문서 및 분석을위한 소설 시스템을 도입하기 위해 신뢰할 수있는 절차를 보여줍니다. 우리가 쉽게 실시간으로 인식 phosphenes의 위치와 크기를 기록 시스템을 구축하고 운영 체제를 추적 및 회화 레이저 (LTaP), 낮은 비용을 개발했습니다. LTaP 시스템 phosphenes의 부량 및 분석을위한 안정적이고 사용자 정의 환경을 제공합니다.
