3D Spine Analysis Software (3dSpAn)

3D Spine Analysis Software (3dSpAn) performs three-dimensional segmentation and quantitative morphological analysis of dendritic spines from microscopy imaging data.

Key Features:

• 3D Multi-Scale Segmentation: Applies a three-dimensional multi-scale opening algorithm within a shared intensity space to segment dendritic spines from dendrites.
• Preprocessing and ROI Selection: Processes microscopy images and enables definition of regions of interest for focused analysis.
• Intensity Thresholding and Seed Detection: Uses intensity-based thresholding and seed selection to initiate segmentation of dendritic spines.
• Quantitative Morphological Feature Extraction: Extracts and quantifies morphological characteristics of segmented dendritic spines.
• Microscopy Data Compatibility: Supports imaging datasets generated from in vitro and ex vivo confocal microscopy and in vivo high-resolution two-photon microscopy.

Scientific Applications:

• Neuroscience Morphological Analysis: Quantifies dendritic spine morphology to study synaptic structure and plasticity.
• Neural Connectivity Research: Enables structural analysis of dendritic spines to investigate neuronal connectivity and network organization.
• Neurodevelopmental and Neurological Disorder Studies: Supports investigation of dendritic spine structural changes associated with neurological conditions.

Methodology:

The software preprocesses microscopy images, selects regions of interest, performs intensity thresholding and seed detection, segments dendritic spines using a three-dimensional multi-scale opening algorithm in a shared intensity space, and extracts quantitative morphological features from segmented structures.
