Table 2.
Proportions of different excitatory interneuron populations that were calretinin-immunoreactive
| Number of neurons examined in each population | % of these neurons that are CR-immunoreactive | % of CR-immunoreactive neurons that belong to each population | |
|---|---|---|---|
| NTS+ | 61.7 (51–69) | 0% (0%) | |
| PPTB+ | 50.3 (48–53) | 84.0% (79.2–86.8%) | 20.8% (19.7–22.5%) |
| PKCγ+ | 89.3 (71–104) | 49.5% (46.2–55.9%) | 21.7% (17.6–25.1%) |
| PKCγ+/PPTB− | 64 (48–75) | 34.4% (29.2–42.0%) | 10.8% (7.5–12.6%) |
| PPD+/Pax2− | 30.7 (23–39) | 5% (0–10%) | |
| GRP-eGFP | 217 (174–256) | 55% (48.9–61.5%) | 18.9% (17.1–21.1%) |
| Tac1+/Pax2− | 104 (90–130) | 73.2% (71–75.6%) | 34.5% (29.3–41.1%) |
The second column shows the numbers of cells examined per mouse among each of the classes listed in column 1, and the third column shows the proportion of these that were calretinin-immunoreactive. In some cases, the proportion of laminae I-II calretinin-immunoreactive cells that were also immunoreactive for the other marker was determined, and this is shown in the fourth column. Ranges are in brackets.
