Retrograde tracing is a research method used in neuroscience to trace neural connections from their point of termination -LRB- the synapse -RRB- to their source -LRB- the cell body -RRB- .. neuroscience. neuroscience. synapse. synapse. cell body. cell body. Retrograde tracing techniques allow for detailed assessment of neuronal connections from a single population of neurons to their various targets throughout the nervous system .. nervous system. nervous system. These techniques allow the `` mapping '' of connections between neurons in a particular structure -LRB- e.g. the eye -RRB- and the target neurons in the brain .. eye. human eye. brain. human brain. The opposite technique is anterograde tracing , which is used to trace neural connections from their source to their point of termination -LRB- i.e. from cell body to synapse -RRB- .. synapse. synapse. cell body. cell body. anterograde tracing. anterograde tracing. Both the anterograde and retrograde tracing techniques are based on the visualization of axonal transport .. axonal transport. axonal transport
