          Interactions between instruction visualisations and task mental representations in skill acquisition is arguably knowledge-domain dependent. This paper presents the design and preliminary results of an experiment that extends the knowledge-domain dependent model to the acquisition of spatial navigational skills. A between-group design is proposed and tested to compare post-learning navigational performances of different learner groups in a virtual environment. The preliminary results indicate a benefit of dynamic over static visualisations in the acquisition of spatial navigational skills, which is consistent with previous results. A full study with a larger sample size and multi-level comparative analysis is currently underway.

          Choice-specific sequences in parietal cortex during a virtual-navigation decision task

          The posterior parietal cortex (PPC) plays an important role in many cognitive behaviors; however, the neural circuit dynamics underlying PPC function are not well understood. Here we optically imaged the spatial and temporal activity patterns of neuronal populations in mice performing a PPC-dependent task that combined a perceptual decision and memory-guided navigation in a virtual environment. Individual neurons had transient activation staggered relative to one another in time, forming a sequence of neuronal activation spanning the entire length of a task trial. Distinct sequences of neurons were triggered on trials with opposite behavioral choices and defined divergent, choice-specific trajectories through a state space of neuronal population activity. Cells participating in the different sequences and at distinct time points in the task were anatomically intermixed over microcircuit length scales (< 100 micrometers). During working memory decision tasks the PPC may therefore perform computations through sequence-based circuit dynamics, rather than long-lived stable states, implemented using anatomically intermingled microcircuits.

              Tracking route progression in the posterior parietal cortex.

               Douglas Nitz (2006)
              Quick and efficient traversal of learned routes is critical to the survival of many animals. Routes can be defined by both the ordering of navigational epochs, such as continued forward motion or execution of a turn, and the distances separating them. The neural substrates conferring the ability to fluidly traverse complex routes are not well understood, but likely entail interactions between frontal, parietal, and rhinal cortices and the hippocampus. This paper demonstrates that posterior parietal cortical neurons map both individual and multiple navigational epochs with respect to their order in a route. In direct contrast to spatial firing patterns of hippocampal neurons, parietal neurons discharged in a place- and direction-independent fashion. Parietal route maps were scalable and versatile in that they were independent of the size and spatial configuration of navigational epochs. The results provide a framework in which to consider parietal function in spatial cognition.
