TACI: 3D カルシウムイメージング解析のための ImageJ プラグイン

Overview

This study discusses the TrackMate Analysis of Calcium Imaging (TACI), an open-source ImageJ plugin designed for 3D calcium imaging analysis. TACI effectively addresses motion on the z-axis and allows researchers to identify the maximum intensity of neurons separated in the z-direction. It enhances the accuracy of calcium imaging in overlapping neuronal environments.
