Performance in all tasks (latency to platform, time spent in target quadrant) was recorded by a computer-based video tracking system [21].
For both gap and overlap tasks latency was measured as the time between target onset and saccade onset.
The standard neuropsychological test protocol should at least consist of the revealed sensitive tasks, i.e. object naming, verbal fluency, verbal word learning and Trailmaking Test B. The language domain appeared to be the most dynamic with standardised tasks, latency effects (naming time) and spontaneous speech.
The present study shows a distance effect for both tasks: latencies increase with distance increase.
However, looking at the mean values of latencies (Table 2), we can observe that in both tasks latencies elicited by small distance probe type were longer than latencies elicited by large distance probe types.
In both pseudo-conditioned groups which did not learn the task, latency on D+5 was similar to that of pre-training level (p>0.05 in massed and spaced pseudo-conditioned groups).
Moreover, we conducted voxel-wise multiple linear regression analyses with performance on the emotion-processing task (latency to respond to angry, fearful, or happy faces) as independent measures, and the percent signal change between faces and the sensorimotor control condition as the dependent measure using the lm program of R.
In conclusion, mice showed good working memory performance on the radiolarian maze, showing a decrease in task latency, omission errors and re-entry errors.
The four variables analysed were the total number of visits, task latency, omission errors, and re-entry errors, measured as a percentage of the total.
Reference memory errors, re-entry errors, commission errors, omission errors, task latency, order of arm visits and the total number of visits were scored.
Values for task latency, the total number of visits, number of omission errors, and the percentages of reference memory, working memory and commission errors were analysed.
