Table 2.
Percentages of neurons in laminae I-III that were galanin immunoreactive
| Number of neurons counted | galanin-immunoreactive cells | % of neurons that were galanin-immunoreactive | % of neurons that are GABA-immunoreactive* | Estimated % of GABA neurons that contain galanin | |
|---|---|---|---|---|---|
| I | 91.3 (80 - 97) | 6 (5 - 8) | 6.6 (5.2 - 8.2) | 24.8 | 26.4 |
| II | 200 (175 - 220) | 6 (4 - 8) | 3.1 (1.8 - 4.6) | 31.3 | 9.9 |
| IIo | 116.7 (99-127) | 5.7 (4-7) | 5 (3.2-7.1) | ||
| IIi | 83.3 (76-96) | 0.3 (0-1) | 0.4 (0-1.3) | ||
| III | 131.7 (104-155) | 2.7 (1 - 5) | 2 (0.7 - 3.2) | 40.2 | 4.9 |
In each case the mean values for the 3 animals are shown, with the range in brackets. * The percentages of neurons in each lamina that are GABA-immunoreactive are taken from the data for the L4-5 segmental levels of 3 naïve Sprague-Dawley rats examined by Polgár et al. [1].
