Glossary ======== .. glossary:: **Model** In DendroTweaks, a computational representation of a neuron that includes its morphological structure, membrane properties, and simulation parameters necessary for numerical simulation. **Tree graph** A hierarchical graph structure where nodes are connected by edges, with no cycles and a single path between any two nodes. **Node** The fundamental unit of which graphs are formed. **Edge** A connection between two nodes in a graph. **Tree traversal** An algorithmic process of visiting each node in a tree graph exactly once. **Reconstruction** A digital representation of a neuron's three-dimensional morphology, composed of interconnected points with spatial coordinates. **SWC file** A standard text-based file format for storing neuronal morphology data, where each line represents a point with its type, coordinates, radius, and parent point index. **Point** A discrete location in 3D space representing a specific position in a neuronal reconstruction, defined by x, y, z coordinates and associated properties. **Section** A continuous unbranched segment of a neuron between points of topological change (bifurcations). **Domain** A collection of sections sharing common morphological or physiological characteristics, typically corresponding to parts of a neuron such as soma, dendrites, axon, etc. **Segmentation** The process of dividing a section into smaller segments to discretize the spatial domain for numerical simulation. **Segment** A small subunit of a section resulting from the segmentation process, used to approximate the spatial properties of a neuron. **Segment Group** A collection of segments selected based on specific criteria such as domain, diameter, or distance. **Membrane mechanism** A mathematical model describing the electrical properties of a neuronal membrane, such as ion channels and pumps. **MOD file** A NEURON-specific file containing the implementation of membrane mechanisms, defining their mathematical equations and computational behavior. **Parameter** A quantitative variable describing specific neuronal properties, such as membrane capacitance, ion channel conductance, or other physiological characteristics. **Distribution** A mathematical function that assigns parameter values across neuronal structures based on spatial or morphological relationships. **Synapse** A specialized junction enabling signal transmission between neurons, represented computationally as a point of conductance and kinetic changes. **Population** In DendroTweaks, a group of "virtual" neurons that form synapses on the postsynaptic neuron (the model). The synapses in a population share the same kinetic and activation properties.
