Tracking Route Progression in the Posterior Parietal Cortex

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