この手法は、突然、恒久的なかつ完全な前庭機能の損失を作成する便利な方法です。これは、前庭神経炎、聴神経腫瘍やメニエール病などの前庭疾患を勉強される可能性があります。多くの研究は、前庭神経核の神経細胞の可塑性や関連する中央プロセス5,17,18,19を研究するのにこの手法を使用し...

前庭器官は、バランスと目のコントロールは欠かせません。通常の前庭機能は、2 つの内側の耳の前庭器官から対称の求心性信号によって異なります。前庭機能低下または損失は、めまい、眼振、姿勢の不均衡を誘導します。急性損傷後前庭機能が自発的に回復数日前庭代償1,2として知られているプロセス。静的な赤字の前庭代償は、安静時自発同側および対側の前庭神経核間の不均衡に関連する回復のプロセスです。動的赤字の前庭代償を達成した主を介して感覚と行動置換 (視覚や体性感覚の入力を使用して)3。これらのプロセスが神経可塑性研究4、5の魅力的です。
前庭系と前庭代償、外科および化学なるほどなど前庭神経切断5,6 中神経可塑性を支えるメカニズムを検討するいくつかの方法が開発されています。 ,7,8。前庭神経切断完了の前庭系障害を誘発する特定の方法が難しく、侵襲的なプロシージャで、脳損傷8,9を引き起こす可能性があります。このメソッドは、高度な外科的スキルが必要です、なるほどより時間かかります。ゲンタマイシン、arsanilate、テトラカインなど化学なるほどが簡単で信頼性の高い結果10、11,12をもたらすことができます。しかし、蝸牛が壊れているも可能性が、前庭系障害時間11に発展するかもしれない。さらに、化学物質の正確な評価のために維持されるべき、脳に及ぼす影響は明確ではありません。手術なるほど 184215の動物研究で初めて導入されました、1936年16でラットに初めて報告されました。この手法が多く使われており動物研究5,17,18,19。手術なるほど、特定の信頼性の高い、比較的単純な方法であります。13,14また、前庭障害の症状は、手術後すぐに見られています。ここでは、ラットなるほどに対する私たちの手技について述べる。
