Moreover, higher BDNF ratios were associated with longer task acquisition.
After task acquisition, the rats were tested using the 40 s delay and a 10 min delay.
In contrast, polyI C-treated offspolyI C-treateded span capacity in the middle and late phases offspringpan task acquisition.
We designed two experiments to determine whether passive heat stress (1) facilitated motor cortex excitability and (2) improved motor task acquisition compared to no heat stress.
There were no significant effects of sex for task acquisition, accuracies across retention intervals, or patterns of adjacent holes or errors chosen.
The early-lesion group also demonstrated increased response latencies for the S2 stimuli during task acquisition, this was also true for task retention in the late-lesion group.
On a probe trial 24 h following task acquisition, rats previously exposed to TMT predominantly displayed response learning relative to control animals.
However, since these studies investigated the effects of dorsal striatal lesions on task acquisition, which can be confounded by differences in level of reinforcement and motor impairment caused by the lesion, the interpretation of these findings was somewhat problematic.
Our results indicate that A. geoffroyi clearly outperforms Macaca nemestrina with regard to the speed of initial task acquisition and the ability to master transfer tasks, and shows a sensitivity to a food-related odorant which matches that of other primate species.
This confirmed group differences in task acquisition.
Here, we showed that learning promotes astrogliogenesis independently of the degree of task acquisition.
