an in vitro preparation for eliciting and recording feeding motor programs with physiological movements in aplysia californica

多機能、複数の、そして、異なった行動を生成するには1つの周辺構造の能力は、動物が急速に変化する環境に自分の行動を適応することができます。海洋軟体動物アメフラシカリフォルニは多面的機能の研究のための扱いやすいシステムを提供します。授乳中は、 アメフラシは同じ送り装置、頬質量を用いて行動のいくつかの異なったタイプを生成します。これらの行動を制御する神経節の電気生理学的研究からアクセス可能な、大規模で識別されたニューロンの数を含んでいます。これらのニューロンの活性がprotracts縮みグラスパー2その神経活動に対する相対食品グラスパーを閉じ神経活動のタイミングに基づいて2種類、ingestiveとegestiveプログラム、に分けることができ、モータのプログラムに記載されている。しかし、単離された神経節で、これらの行動を生み出すであろう筋肉の動きは、それを作って、欠席している観測されたモータのプログラムは、実際の行動の相関があるかどうか。 生体 、神経と筋肉のレコーディングでは、特定することが難しいが2,3,4給餌プログラムに対応して得られますが、それは直接個々のニューロン5から録音することは非常に困難であるされています。さらに、in vivoで 、ingestiveプログラムは、さらに刺され、ツバメの1,2、最も以前にin vitro標本で説明で行うことが困難である区別に分けることができます。 中断頬大量調製（ 図1）は、孤立した核と無傷の動物の間のギャップを埋めます。この準備として、ingestive行動-かむと嚥下の両方を含む-とegestive行動（拒否）は、個々の神経細胞は、細胞外から記録電極6を使用して刺激することができると同時に、誘発することができます。これらの異なる動作に関連付けられている餌の動きがrecorすることができますDEDに、定量化、およびモータのプログラムに直接関係する。中断頬大量調製におけるモータープログラムは孤立核において誘発運動プログラムよりもin vivoで観察されたものにもっと似ているように見える。したがって、この準備のモータのプログラムは、より直接的に生体内挙動にに関連することができます。同時に、個々の神経細胞は無傷の動物よりも記録と刺激によりアクセス可能です。また、孤立した核と無傷の動物との間に中間のステップとして、中断頬塊から得られた知見は、より減少し、より完全な両方の設定で得られたデータの解釈を助けることができます。中断頬マスの準備はアメフラシにおける多面的機能の神経制御を特徴づけるための便利なツールです。

When an extracellular electrode is positioned above a neuron's soma and used to stimulate the neuron, a one-for-one correspondence between spikes on the soma channel and on the nerve(s) the neuron projects to can be observed (Figure 6, left panel, stimulation of identified neuron B9). The soma channel (top channel) is set to stimulating mode when the current is applied (time 1 in the figure), and is then quickly switched to recording mode (time 2). By maintaining the position of the electrode, the...
