These configurations were evaluated regarding their crack turning behaviour (T-stress).
The severity of these changes appears to depend on the degree of dopamine depletion [8, 9], as corroborated by [18F]FDG-PET which found decreased glucose metabolism in ipsilesional motor brain areas to correlate with apomorphine-induced turning behaviour [10].
A well-fitting example might be the turning behaviour to escape from a predator in shoaling fish species.
In addition, varying the motivation for turning behaviour or the placement and type of visual cues [36] could further define the contexts under which laterality will be expressed or masked.
Chemokinesis however, is motility in response to soluble factors in the absence of a gradient, involving a change in speed or turning behaviour.
The left and right turning behaviour was measured at day −1 for baseline measurements and at day 1, 3, 7 and 14 after intracerebral OVA injection.
LIII hemocytes that had been ecdysone treated exhibited similar behaviours to WPP (Fig. 2A,B; supplementary material Movie 5), such as polarisation and turning behaviour, that was not observed at the LIII.
Specifically, animals were placed into cylindrical, flat-bottomed chambers of 40 cm diameter, injected i.p. with 0.4 mg apomorphine/kg body weight and their turning behaviour recorded with a video camera for offline analysis.
Furthermore, in order to assess whether animals in Experiment 2 had an asymmetric, postural and/or motoric deficit caused by the unilateral lesions, we also used two standard tests of rotational (turning) behaviour.
Both frequency and duration of ipsilateral rotations increased through the course of the experiment, while we detected no significant preference for turning behaviour at any time after expression of the control shRNA.
