  1. Sex is given as M for male and F for female. Transport gives the survival time of the animal post-injection which was available for active transport of the tracers. If the amount of tracer is given by a range, the fluid meniscus in the glass pipette was between the two marker lines. Approach describes the trajectory of the electrode, either from posterior or entering dorsally. LIP gives the subdivision where the injection site was placed (d-dorsal; v-ventral). Injection site describes the layers where we found discernible tracer deposits from the injection. We would need more animals and even smaller injection sites to systematically assess the impact of layer on the pattern of connectivity.
