Retrosplenial Cortex Indexes Stability beyond the Spatial Domain
Retrosplenial cortex (RSC) is highly responsive to landmarks in the environment that remain fixed in a permanent location, and this has been linked with its known involvement in scene and spatial processing. However, it is unclear whether RSC representations of permanence are a purely spatial phenomenon or whether they extend into behavioral and conceptual domains. To test this, during function...
متن کاملEncoding and storage of spatial information in the retrosplenial cortex.
The retrosplenial cortex (RSC) is part of a network of interconnected cortical, hippocampal, and thalamic structures harboring spatially modulated neurons. The RSC contains head direction cells and connects to the parahippocampal region and anterior thalamus. Manipulations of the RSC can affect spatial and contextual tasks. A considerable amount of evidence implicates the role of the RSC in spa...
متن کاملWhat does spatial alternation tell us about retrosplenial cortex function?
The retrosplenial cortex supports navigation, but there are good reasons to suppose that the retrosplenial cortex has a very different role in spatial memory from that of the hippocampus and anterior thalamic nuclei. For example, retrosplenial lesions appear to have little or no effect on standard tests of spatial alternation. To examine these differences, the current study sought to determine ...
متن کاملTemporary inactivation of the retrosplenial cortex causes a transient reorganization of spatial coding in the hippocampus.
The ability to navigate accurately is dependent on the integration of visual and movement-related cues. Navigation based on metrics derived from movement is referred to as path integration. Recent theories of navigation have suggested that posterior cortical areas, the retrosplenial and posterior parietal cortex, are involved in path integration during navigation. In support of this hypothesis,...
متن کاملTesting the importance of the caudal retrosplenial cortex for spatial memory in rats.
Although there is evidence to suggest that the retrosplenial cortex is involved in spatial learning and memory, many lesion studies have left the more caudal part of this region intact so leaving its role untested. In the first experiment, rats with neurotoxic lesions of the caudal half of the retrosplenial cortex (RspC1) were tested on a reference memory task in the water-maze. The RspC1 anima...
