Topic: reference frames

Humans efficiently reason about space to navigate and forage in new environments, which may, at least in part, depend on an ability to generalize across tasks and organize observations into patterns that can be re-used. Generalization and transfer learning in spatial domains is evident in mirror-invariant neural scene representations, and in the reuse of reference frames and representations across similar environments. Shared reference frames appear in other mammals as well, as, for example, in rodents reusing grid-cell maps for different but perceptually similar environments. However, the fie

Center-surround processing (CSP) is a ubiquitous feature of the brain, starting from early sensory processing (e.g., context-dependent retinal encoding) to representing abstract concepts (e.g., context-dependent object representation), manifesting itself in both behavior and neural responses. CPS in neural responses is typically modeled using normalization models or in purely descriptive terms. However, a normative model that could enhance our understanding of the function of CSP and link these neural effects to behavior is still lacking. Here, we build on a recently developed normative model
