Histochemical tracer

A histochemical tracer is a compound used to reveal the location of cells and track neuronal projections. A neuronal tracer may be retrograde, anterograde, or work in both directions. A retrograde tracer is taken up in the terminal of the neuron and transported to the cell body, whereas an anterograde tracer moves away from the cell body of the neuron.
