Figure 7.

Patterns of ipsilateral (A) and contralateral (B) cortical connections resulting from a large injection of BDA that contained portions of FM, SR, and S1 for case 09-32. Moderate label is widely distributed across multiple cortical fields including FM, S1, S2, SR. One of the most dense and widespread labeled areas is in EC and piriform cortex. Sparse label was also widely distributed and found is SC, MM, A1, V2 and V1. The black box shows the region of cortex in the inset BDA and myelin stained sections. The arrow points to the injection site. In the contralateral hemisphere dense label was observed in FM and cortex just rostral to FM and moderate label was observed in SR and S1, SC and piriform cortex. Sparse label was observed in SC. In this case, electrophysiological recordings were performed to confirm the placement of the tracer injection. (C) Injection site and adjacent electrophysiological map of S1 as well as the location of a receptive field for neurons at a recording site located within the injection zone (light blue shading on animal face). Conventions as in previous figures.
