L-Measure

L-Measure quantifies neuronal morphology by computing comprehensive neuroanatomical parameters from 3D digital reconstructions to support morphometric analysis.

Key Features:

• Quantitative Morphological Analysis: Computes a comprehensive array of neuroanatomical parameters from 3D digital reconstruction files.
• Basic Morphological Parameters Extraction: Extracts fundamental morphological parameters from neuronal reconstructions.
• Frequency Distributions Computation: Computes frequency distributions for morphometric data.
• Subregion Measurements: Measures specified subregions within neuronal arbors.
• Statistical Comparisons: Performs statistical comparisons between two groups of cells.
• Filtered Selections and Searches: Selects and searches collections of neurons using any Boolean combination of available morphometric measures.
• Input Compatibility: Accepts 3D digital reconstruction files from applications such as Neurolucida, Eutectic, and Neuron_Morpho and outputs from computational simulations.
• Performance: Executes analyses rapidly, typically processing approximately 20 neurons within minutes.

Scientific Applications:

• Structure–function analysis: Enables detailed morphological analyses to investigate neuronal structure–function relationships.
• Anatomical characterization: Supports basic anatomical characterization of individual neurons and neuronal arbors.
• Comparative morphometrics: Facilitates comparative analyses across different experimental conditions or cell types.

Methodology:

Processes 3D digital reconstruction files obtained through brightfield or fluorescence microscopy using applications such as Neurolucida, Eutectic, or Neuron_Morpho, and accommodates computational simulations.
