How do #ctenophores control their sense of balance "without a brain"?
We used connectomics to uncover the neural network behind their gravity sensing!

#クシクラゲ の平衡器官を構成する900個の細胞のネットワークを３次元的に再構築し、重力センサーの神経回路からその制御機構の謎に迫りました。
重力センサーの動きを高速度カメラで撮影し、その同期・非同期パターンから、これまで謎に包まれていたクシクラゲの神経の機能に焦点を当てています。

クシクラゲの融合
有櫛動物はクラゲに似たゼラチン質の海洋生物でクシクラゲとも呼ばれているが，マサチューセッツ州にあるウッズホール海洋生物学研究所の研究者は奇妙なものに気づいた。
尻が2つある個体がいたのだ。
