Neuron tracing, or Neuron reconstruction is a technique used in neuroscience to determine the path of neural axons and dendrites (many times also called neuronal processes). From a sample preparation point of view, it may refer to some of the following as well as other genetic neuron labeling techniques, * Anterograde tracing, for labeling from the cell body to synapse; * Retrograde tracing, for labeling from the synapse to cell body; * Viral neuronal tracing, for a technique which can be used to label in either direction. In broad sense, neuron tracing is more often related to digital reconstruction of a neuron's morphology from imaging data of above samples. == Digital Neuron Reconstruction and Neuron Tracing == Digital reconstruction or tracing of neuron morphology is a fundamental task in computational neuroscience. It is also critical for mapping neuronal circuits based on advanced microscope images, usually based on light microscopy (e.g. laser scanning microscopy, bright field imaging) or electron microscopy or other methods. Due to the high complexity of neuron morphology and often seen heavy noise in such images, as well as the typically encountered massive amount of image data, it has been widely viewed as one of the most challenging computational tasks for computational neuroscience. Many image analysis based methods have been proposed to trace neuron morphology, usually in 3D, manually, semi-automatically or completely automatically. There are normally two processing steps: generation and proof editing of a reconstruction. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Neuronal tracing」の詳細全文を読む スポンサード リンク
