In rivers, turbulence and flow may continually disrupt the visual landscape such that river fish may benefit from learning orientation routes only if learning is constrained so that unreliable visual cues are ignored.
We investigated whether the use of local landmarks in learning orientation routes by the three-spined stickleback, Gasterosteus aculeatus, varied in response to the visual stability of their natural habitats.
VHQ (Velocity-oriented Horizontal Quad): The frame describes the orientation of the route elements with respect to the direction towards the pole in the LTL frame.
Identifying the location of wayfinding aids, and further, the current location, destination, orientation and horizontal route on the wayfinding aids.
However, in cases where people deviate from a specific route, orientation strategy will help establish their position by relying on local cues (Lawton 1996).
In Lawton's theory (Lawton 1996), there are two main strategies for wayfinding in indoor environments—orientation strategy and route strategy.
The orientation of these route networks in part was determined by settlement locations, and in part by environmental factors (e.g. soil type, relief).
It was found that students in the virtual orientation recalled spatial route details better than the participants in the authentic orientation, while there was no significant difference between the groups in terms of spatial landmark details and overall spatial scores.
In the specific model, the constant phase increment Δ ϕ = 2 π f max cos cos ( π − θ e l e v ) T s, with ϕ and θelev being the relative azimuth (route orientation with respect to the satellite) and elevation angles, respectively.
Radial glial fibers extend from the telencephalic VZ to the cortical regions (i.e. the medial, dorsal and lateral pallium) (März et al., 2010; Ganz et al., 2010), and this orientation parallels the route of the migrating NPCs (Fig. 4C, Fig. 5B).
