Spatial distribution of immunoreactivity reported as a percentage of surface membrane voxels
| Processes | ||||
|---|---|---|---|---|
| Soma | Primary | Secondary | Tertiary | |
| PACAP (n = 6) | 10.1 ± 3.4 | 35.9 ± 7.4 | 32.1 ± 6.0 | 21.9 ± 9.1 |
| PAC1-R (n = 7) | 18.8 ± 3.5 | 12.7 ± 2.3 | 35.3 ± 6.1 | 33.3 ± 6.0 |
| VIP (n = 7) | 21.3 ± 4.9 | 22.8 ± 2.9 | 27.4 ± 4.7 | 28.5 ± 7.1 |
| nAChR (n = 6) | 23.6 ± 5.6 | 21.9 ± 2.8 | 25.8 ± 5.3 | 28.7 ± 4.8 |
| VAChT (n = 3) | 14.5 ± 8.3 | 21.7 ± 3.1 | 36.8 ± 7.6 | 27.0 ± 8.2 |
Neuronal receptor regions were defined as surface membrane voxels that also contained immunoreactivity for receptor antibodies. Presynaptic nerve endings were defined as external structures immunopositive for PACAP, VIP VAChT that were within 1 voxel dimension of the neuronal surface membrane.
