Behavioral tests in rodent models of stroke
2020, Brain HemorrhagesCitation Excerpt :They are widely used to evaluate functional outcome after stroke.122 The skilled reaching tasks are a series of tasks that train animals to reach their limbs through limited space, such as slots, staircases, or tubes.123–125 Food pellets are commonly used to trigger the reaching behavior.
Mouse Arm and hand movements in grooming are reaching movements: Evolution of reaching, handedness, and the thumbnail
2020, Behavioural Brain ResearchCitation Excerpt :The variety of hand shapes displayed by a grooming mouse supports the idea that the hand is a flexible tool that adapted to many purposes. Contemporary theories of skilled hand use include suggestions that reaching evolved from stepping or digging [46], from balancing on the fine branches of trees to obtain food [47–49,67] or from the act of food eating [8,10,66]. Work using long-duration intracortical microstimulation also shows that the cortex is topographically organized into discrete functional areas of motor primitives that map out behavioral repertoires [30,34].
Directional Reaching for Water as a Cortex-Dependent Behavioral Framework for Mice
2018, Cell ReportsCitation Excerpt :The average duration of a complete sequence (from START to end of DRINK) was 1.83 ± 0.39 s in freely reaching mice and 1.93 ± 0.35 s in restrained mice, and the duration of each phase was not statistically different between conditions (Table 1). Notably, the basic reach-to-grasp sequence was already observed at the earliest trials in naive mice (Figures S1A), suggesting a preexisting innate motor pattern for this behavior (Brácha et al., 1990). Taken together, the observed reach-to-grasp sequence for liquid rewards closely resembles reaching behaviors previously described in mice, rats, and humans (Guo et al., 2015; Klein et al., 2012; Whishaw and Pellis, 1990).
A behavioral method for identifying recovery and compensation: Hand use in a preclinical stroke model using the single pellet reaching task
2013, Neuroscience and Biobehavioral ReviewsCitation Excerpt :Each subcomponent can be differentially affected by stroke, and so the organization of these movements provides an index of the effect of stroke and a means of identifying compensatory and recovery process. Is skilled reaching by the rat similarly organized, or is it a modification of some other behavior, such as stepping, digging, or climbing (Bracha et al., 1990; Whishaw et al., 2010). If rat skilled reaching is simply a modification of some other movement, it is possible that it is idiosyncratic to each rat and thus not diagnostic.
Breeder and batch-dependent variability in the acquisition and performance of a motor skill in adult Long-Evans rats
2011, Behavioural Brain ResearchCitation Excerpt :Thus, additional analysis of reaching strategies among the rats from different breeders could provide important insight into observed reaching differences. In addition to the single pellet retrieval task, there are other types of reaching tasks used to test forelimb function and study motor skill learning, including the Montoya staircase task [59,60], tray reaching tasks [19,61], and the pasta matrix reaching task [62]. Like the single pellet retrieval task used in the current study, these reaching tasks also require fine motor skill learning with the forelimb, including skillful reach-to-grasp movements.
