Cell type-specific morphological analysis of arbor area in tectal neuropil.
| SM | SFGS | Tectal | ||||||
|---|---|---|---|---|---|---|---|---|
| Label | 23c | 23c single axon | PyrN-SM | isl2b | RGC-SFGS6* | PyrN-SFGS | HuC | PyrN-SGC |
| Area (μm2) | 12857.7 ± 240.8 | 10382.4 ± 527.5 | 491.7 ± 51.4 | 18766.3 ± 135.2 | 1251.2 ± 130.7 | 481.7 ± 33.7 | 25670.4 ± 719.2 | 1048.2 ± 88.7 |
| N | 8 | 16 | 16 | 8 | 21 | 16 | 8 | 16 |
| Percent of total | 100% | 81.3% | 3.8% | 100% | 6.7% | 2.6% | 100% | 4.1% |
SM measurements indicate area occupied by the axonal plexus (23c), single TL axons, and single PyrN SM dendrites. SFGS measurements indicate area occupied by RGC terminal arbors (isl2b), single RGC axons, and single PyrN SM dendrites. Area measurements for single PyrN SGC dendrites expressed as percentage of tectal neuropil area determined by pan-neuronal HuC labeling. Note the large axonal territories of single TL axons in SM. All data are presented as mean ± SEM.
