Rats can use multiple cue-types to perform spatial alternation tasks (e.g., Douglas, 1966; Dudchenko, 2001), including visual allocentric cues, intra-maze cues (e.g., odor trails), directional cues (i.e., bearing), and egocentric cues (i.e., body turns).
The significance of this work is revealed in its far greater integration of the traditional Japanese instruments into the orchestral discourse; whereas in November Steps, the two contrasting instrumental ensembles perform largely in alternation, with only a few moments of contact.
The Materials and Methods section describes the methodology for a pilot project that we performed on alternations in biomedical verbs, and then describes a much more extensive experiment involving nominalizations.
This difference between partial and total alternation performances could be explained by the fact that partial alternation is easier to perform for the animals than total alternation, hence the lack of effect in the first task.
Her solo was made for the exquisitely gracious Svetlana Beriosova: in its opening phrase, advancing down a diagonal, she performs an extraordinary alternation of steps.
The behavioral data were collected from a total of 12 mice performing a delayed alternation task in two configurations of a T-maze.
The current study examined the effects of these low, orally-administered doses of MPH in rats performing a delayed alternation task dependent on prefrontal cortex (PFC), a brain region that is dysfunctional in ADHD, and is highly sensitive to levels of catecholamines.
Under stress conditions, cell performs several adaptive alternations to protect against cell death, such as autophagy.
At the longest delay tested (60 s), both SREB2 Tg and WT mice showed impaired performance compared with the SREB2 KO mice, which still performed at above random alternation (% correct: WT, 47.5 ± 5.3, n = 8; SREB2 KO, 68.6 ± 8.6, n = 8; SREB2 Tg, 37.5 ± 8, n = 8; post-hoc KO vs. WT, P < 0.05; KO vs. Tg, P < 0.05, Fig. 8B).
For this purpose, two kinds of cyclic R-ratio loading tests are performed; one is under alternation of equal-life waveforms of different R-ratios, and the other is under alternation of unequal-life waveforms of different R-ratios.
