a novel approach for documenting phosphenes induced by transcranial magnetic stimulation

人間の視覚野の刺激は、閃光と呼ばれる光の一時的な知覚を生成します。閃光は、後頭部皮質の侵襲的な電気刺激によって、だけでなく、非侵襲的な経頭蓋磁気刺激（TMS）により誘発される<sup&gt; 1</sup&gt;同じ皮質領域の。閃光が誘導される強度（閃光閾値）は視覚野興奮性の十分に確立された指標であり、皮質 - 皮質の相互作用、機能的な組織を研究するために使用されます<sup&gt; 2</sup病理へ&gt;、感受性<sup&gt; 3,4</sup&gt;と視覚処理<sup&gt; 5月7日</sup&gt;。被験者の目が開いているか閉じているときに彼らが誘導され、視線の方向との空間的位置の変更は、それらが刺激に対側半側視野で観察されています：閃光は、通常、次の3つの特性によって定義されます。<sup&gt; 2</sup&gt;。様々な方法が閃光を文書化するために使用されているが、標準化された方法論が欠如している。我々は閃光閾値の値を取得し、閃光のドキュメントと分析のための新しいシステムを導入する信頼性の高い手順を示しています。我々は、簡単にリアルタイムで認識閃光の位置とサイズを記録するシステムを構築運用システムを追跡し、絵画レーザー（LTaP）、低コストを、開発した。 LTaPシステムは、閃光の定量化と分析のための安定的かつカスタマイズ可能な環境を提供しています。
