The results suggest that beta-adrenoceptors are involved in the regulation of behavior in the place avoidance task and that it is possible to dissociate the effect of propranolol on the spatial performance and locomotion in the AAPA using dose-selection.
However, having a simple, closed-form equation that summarizes the effects of contrast, spatial extent, and locomotion can help guide the search for the underlying mechanisms.
The zone analysis (spatial distribution of locomotion, e.g. periphery versus centre of the open-field) revealed that all mice showed a strong preference for the periphery (F2,60=325.36, P < 0.0001).
On Rock's view, at least some forms of adaptation to ORDs can be explained by our ability to detect and exploit such invariant sources of spatial informational in locomotion-generated patterns of optic flow.
However, our finding that locomotion shapes spatial selectivity makes it unlikely to operate through a global quantity.
On the other hand, Kalirin-7 knockout mice showed decreased spine density in hippocampus and abnormal anxiety-like behavior, but locomotion and spatial working memory are normal in these mice [ 47].
Indeed, the present results demonstrate that at different phases of owl attack, spiny mice and voles change their level of activity, the structure of the trips they take in the environment, and the spatial distribution of their locomotion.
These subchondral bone architecture thought to be associated with local load magnitude during locomotion, a spatial shift in the contact area could place loads on a region of subchondral bone that may not adapt to the rapidly increased load after meniscectomy [ 30].
During this task, we analysed the temporal characteristics and spatial distribution of mouse locomotion using a video tracking system (HVS Image, Buckingham, UK), allowing the automatic calculation of the mean distance travelled, mean speed, percent of time walking slowly (≤5 cm/s), percent of time spent in three concentric rings (central, intermediate and peripheral) and percent of thigmotaxis.
WalkinSense (Kinematix SA, formerly Tomorrow Options, Sheffield, UK) is a user-friendly device designed for in-shoe monitoring and long-term storage of plantar pressure and spatial-temporal parameters during locomotion, such as gait speed, distance traveled, and stride length and frequency, without the need for a standardized calibration and the constraints of a laboratorial setup.
