果蠅腦的座標系統與變形

Abstract

我們研究將果蠅腦變形到一個標準化果蠅腦的問題。在這篇論文裡，我們為果蠅腦定義一個座標系統。基於這個座標系統，我們可以定義出標準化果蠅腦的尺寸。欲變形的果蠅腦，先依照標準化果蠅腦的大小調整尺寸。再利用果蠅腦內的neuropils所決定之特徵點來做變形。實驗結果顯示，變形後的果蠅腦內部結構與外殼和目標腦幾乎對齊。

We study the problem of warping Drosophila brains to a normalized fly brain. In this thesis, we define a coordinate system for the Drosophila brain. Based on the coordinate system, we define a size-normalized brain. Every fly brain is normalized before warping. The warping is based on the feature points determined by the neuropils in the brain. Experimental results show that a brain can be warped to the target brain with the internal structures and the hull of the brain almost aligned.
