TABLE 2.
Firing, burst, and preburst parameters for neurons in four different thalamic nuclei
| Nucleus | Firing Rate, s−1 | Primary Rate, s−1 | Burst Rate, s−1 | Burst Rate/Primary Rate | Preburst ISI, ms | Ratio of PBISI/Inverse PR |
|---|---|---|---|---|---|---|
| LD (n = 13) | 4.2, 3.2–8.0 | 3.5, 2.6–10.2 | 0.34, 0.15–0.46 | 0.085, 0.03–0.21 | 435, 192–586 | 1.53, 1.23–1.82 |
| Vo (n = 36) | 4.4, 3.0–9.4 | 3.2, 2.5–8.9 | 0.12, 0.05–0.20 | 0.035, 0.01–0.09 | 323, 131–433 | 1.19, 1.12–1.57 |
| Vim (n = 42) | 12.3, 8.7–18.7 | 12.3, 7.1–8.4 | 0.21, 0.14–0.34 | 0.020, 0.01–0.03 | 148, 119–219 | 1.99, 1.53–2.28 |
| Vc (n = 26) | 5.2, 3.7–9.5 | 2.9, 2.2–5.7 | 0.67, 0.47–0.86 | 0.260, 0.08–0.41 | 327, 222–422 | 0.96, 0.84–1.35 |
Each cube includes the median and 5th to 95th percentile confidence interval (CI) of the median. Units of each parameter are given in the table headings. Bold and underlined variables for nuclei with median and CI are outliers that are significantly different from nuclei with median and CI shown in bold; e.g., burst rates in Vc are higher than those in Vo and Vim.
