Reaching/grasping frequency in relation to poke.
| Control | 3–5 days | 6–8 days | 9–11 days | 12–14 days | 15–17 days | |
|---|---|---|---|---|---|---|
| R1 | 0.88 | 0 | 0 | 0.5 | 0.52 | 0.90 |
| R2 | 0.93 | 0 | 0 | 0 | 0.8 | 0.99 |
| R3 | 1 | 0 | 0.8 | 1 | 1 | 1 |
| R4 | 1 | 0 | 1 | 1 | 1 | 1 |
| R5 | 1 | 0 | 0.82 | 1 | 1 | 0.99 |
| Average | 0.96 | 0 | 0.45 | 0.70 | 0.86 | 0.98 |
| Std error | 0.02 | 0 | 0.24 | 0.22 | 0.09 | 0.02 |
Ratio between reaching/grasping and poke expressed as a percentage for each animal in controls and at different time intervals after ION severing. This ratio gives an indication of the triggering power of nose insertion into the slot for the subsequent reaching/grasping movement. Note that all control rats present a ratio of almost 1:1. At 3–5 days, poke does not trigger reaching/grasping; in R3, R4 and R5, poke triggers reaching/grasping after 6–8 days, and in R1 and R2 this triggering function reappears later.
