Movements evoked by intracortical microstimulation
| Control | No-delay graft | Delay graft | |
|---|---|---|---|
| Motor responses | 100% | 80% | 83.3% |
| Movements representations | |||
| Forelimb | 73% | 29% | 11% |
| Hindlimb | 24% | 71% | 78% |
| Vibrissa | 3% | 0% | 0% |
| Tail | 0% | 0% | 11% |
Note that electrical stimulation induced overall appropriate motor responses in both transplantation groups, although the sensitivity of grafted cells to electrical stimuli is reduced, particularly in the upper part of the transplants.
