For that reason, a neural substrate for navigation demands spatial and environmental information and the ability to effect actions through efferents. The secondary motor cortex (M2) is a prime candidate for this role given its interconnectivity with association cortices that <strong><span style=\"color: #ff0000;\">encode spatial relationships and its projection to the primary motor cortex<\/span><\/strong>. Here, <strong><span style=\"color: #ff0000;\">we report that M2 neurons robustly encode both planned and current left\/right turning actions across multiple turn locations in a multi-route navigational task<\/span><\/strong>. Comparisons within a common statistical framework reveal that M2 neurons differentiate contextual factors, including environmental position, route, action sequence, orientation, and choice availability. Despite significant modulation by environmental factors, <strong><span style=\"color: #ff0000;\">action planning, and execution are the dominant output signals of M2 neurons<\/span><\/strong>.
