Figure 2.

Somato-dendritic transport differences between primary and association cortical pyramidal neurons. Left: illustrates the experimental approach. Retrograde dye (for transport and staining) was injected into the adult inferior colliculus and staining was subsequently evaluated in both the core and association temporal lobe cortical regions. The core region represents the primary auditory cortical region. Middle: region between the open arrow and solid arrow indicate the association area, while the rostral cortical region (above the solid arrow) represents the core region. Right: single cell images from each region. Note that unlike in the association area, in the core region, somatic and dendritic labeling of single cells was much more evident.
