Away from the constant task of tweaking his already unimprovable musculature, Ronaldo relaxes by swimming, sleeping a strict eight hours and – oh yes – doing 3,000 sit ups a day in front of the television.
Note that in this visuomotor task, as in the constant reaching task, the animal performed a constant arm movement while fixating different spatial locations.
Conversely, when a cell showed an action epoch that was modulated in the foveal reaching task but not in the constant reaching task, we can argue that this cell is able to encode the spatial direction/location of hand movement/position, but not its retinotopic counterpart.
The neuron was activated during the holding phase in the constant reaching task (anova, P < 0.01), showing the strongest discharge when the hand was held on the position gazed by the animal (Fig. 11A, centre).
The X-value of each point is the value of the modulation index calculated for that neuron in the constant reaching task (i.e. the value of its sensitivity to the retinotopic position of the target), the Y-value is calculated in the foveal reaching task (i.e. the value of its spatial modulation).
A portion of V6A neurons is modulated in the constant reaching task only (19% and 26% in MOV and HOLD, respectively), as the cell in Fig. 11, that is they are neurons sensitive to the retinotopic position of the target but not to its spatial position.
Figure 10 shows the responses of the same cell as in Fig. 2B during the constant reaching task (Fig. 10A) and foveal reaching task (Fig. 10B).
As described for the constant reaching task, the foveal reaching task was tested in a sequence of randomized triplets, 15 trials for each condition.
Gathering and sawing driftwood from the estuary for the fire is a constant task.
Several neurons tested with the constant reaching task underwent also another reaching task, in which the yellow cue indicating the reaching target lit up always in the same position as the fixation target.
