Classification of forelimb neurons (n = 40)
| Groups and subgroups | Number of neuronsa | Percent of neuronsa | Tests with CC > 0.6 relative to 2F2H | Sources of modulationb |
|---|---|---|---|---|
| 1-1 | 9 (7) | 22.5 (17.5) | 2F, 2R | FR |
| 1-2 | 7 (6) | 17.5 (15.0) | 2F, 2R, 2L | FR/FL |
| 1-3 | 9 (5) | 22.5 (12.5) | 2F | FR + FL |
| 1-4 | 4 (2) | 10.0 (5.0) | 2F, 2L | FL |
| 2-1 | 1 (1) | 2.5 (2.5) | 2F, 2H, 2R | FR/HR |
| 2-3 | 1 (0) | 2.5 (0.0) | 2F, 2H | FR + FL/HR + HL |
| 3-1 | 4 (2) | 10.0 (5.0) | 2R | FR + HR |
| 3-2 | 2 (2) | 5.0 (5.0) | 2R, 2L | FR + HR/FL + HL |
| 3-3 | 3 (1) | 7.5 (2.5) | — | FR + FL + HR + HL |
aNumber or percentage of antidromically identified neurons is indicated in parentheses.
bConvergence of inputs necessary for generating the modulation pattern similar to that in control is indicated by a plus sign. Equivalence of inputs (or of their combinations) is indicated by a slash.
