A Better Way to Trace Neurons

Caption

These images demonstrate the increased efficiency of the improved retrograde viral tracing method introduced by the Kepecs lab at CSHL. While in one register, a classic tracer (bottom right) performs about as well as the improved one (top right), the improved tracer records neurons far more robustly (top middle) in a different register (green dots). Both tracers were injected in the same place and traced neuronal connections between the basolateral amygdala and the medial prefrontal cortex.
