Seed regions are a critical determinant of the connectome. a) Seed regions (i.e., retroviral injection sites) from the ABCA have been mapped into the MR images of Waxhom Space, with spherical dimensions estimated from the volume of injected tracer. b) Seed regions from Waxholm Space have been derived from anatomic landmarks visible in the scalar images (Figure 1). c) Recent work has resulted in a merger of Waxholm Space canonical MR images with a new set of delineations from ABA (version 3). This will facilitate harmonization of connectomics data with gene expression.
