Circuit Mechanisms Governing Local vs. Global Motion Processing in Mouse Visual Cortex
2017
Frontiers in Neural Circuits
Preserved Fulltext
Although mouse visual cortex lacks the highly ordered orientation columns of primates, it is organized in functional sub-networks and contains striate-and extrastriate areas like its primate counterparts ...
A particularly well-defined visual computation is the representation of global object motion by pattern direction-selective (PDS) cells from convergence of motion of local components represented by component ...
STUDYING LOCAL AND GLOBAL MOTION IN MOUSE VISUAL CORTEX At this time, three groups have probed the existence of CDS and PDS cells in mouse visual cortex (Juavinett and Callaway, 2015; FIGURE 2 | Mouse ...

To achieve these goals within the non-human primate (NHP) imaging community, there is a pressing need for the use of standardized and validated localizers that can be readily implemented across different ...
As has been shown with the aggregation of resting-state imaging data in the original PRIME-DE submissions, we believe that the field is ready to apply the same initiative for task-based functional localizers ...
Importance of functional localizers in the study of primate brain functions Localizers are extensively used in fMRI studies, whether in human or non-human primates, in order to identify cortical regions ...
