Topographic precision in sensory and motor corticostriatal projections varies across cell type and cortical area

Abstract

How corticostriatal connections of different pyramidal cell types are organized, particularly in convergent circuits, has not been evaluated in detail. Here, cell type-specific Cre-driver mice reveal that pyramidal tract-type corticostriatal projections, though broadly similar to intratelencephalic-type projections from the same cortical region, are generally more restricted and variable in their topographic termination patterns.
