Area of Science:

Neuroscience
Biophysics
Computational Biology

Background:

Two-photon imaging generates complex fluorescence data requiring sophisticated analysis.
Functional brain imaging, analogous to functional magnetic resonance imaging (fMRI), necessitates co-registration with anatomical atlases.
Delineating activated brain regions traditionally involves subjective interpretation.

Purpose of the Study:

To present a unified framework for analyzing two-photon fluorescence imaging data.
To enable objective identification of activated brain regions based on correlated activity.
To facilitate the development of a Drosophila functional connectome database.

Main Methods:

Developed a unified framework for analyzing two-photon fluorescence imaging data.
Co-registered functional images with a structural brain atlas.
Demarcated activated voxels by correlating calcium traces with predicted responses, minimizing subjective reasoning.

Main Results:

Demonstrated the framework's efficacy using experimental data from olfactory stimuli in Drosophila.
Successfully normalized functional images into a standard stereotactic space.
Adequately delineated expected brain regions activated by stimuli.

Conclusions:

The proposed framework offers a robust method for analyzing two-photon fluorescence imaging data.
Enables objective and accurate functional brain region delineation in Drosophila.
Paves the way for building a comprehensive Drosophila functional connectome database.
