The relationships of tasks and task comparisons to attentional switching, response reassignment, and movement
| Behavior | Lateral cerebellum | |||||
|---|---|---|---|---|---|---|
| Attention switch | Response reassignment | Δ Motor response | Left lobule VI (−22, −68, −30) | Right lobule VI (22, −66, −22) | Right lobule VI (22, −44, −24) | |

| DOUBLE > FOCUS | Yes | Yes | 0 | Yes | Yes | No |

Across all task conditions the number of targets presented was the same, but the number of movements required was different: the SINGLE conditions only required half as many movements as the FOCUS and DOUBLE conditions. Also shown are cerebellar areas that exhibited a response for the relevant contrasts.
