Pattern and Component Motion Responses in Mouse Visual Cortical Areas.

摘要: Spanning about 9 mm(2) of the posterior cortex surface, mouse's small but organized visual has recently gained attention for its surprising sophistication and experimental tractability. Though it lacks highly ordered orientation columns primates, mouse is retinotopically contains at least ten extrastriate areas that likely integrate more complex features via dorsal ventral streams processing. Extending our understanding perception to model justified by evolving ability interrogate specific neural circuits using genetic molecular techniques. In order probe functional properties putative stream, we used moving plaids, which demonstrate differences between cells identify local motion (component cells) those global plaid (pattern cells; Figure 1A;). there are sparse pattern cell responses in primate V1, many higher-order regions; 25%-30% MT 40%-60% MST direction selective. We present evidence mice have numbers LM RL, while AL, AM largely component-like. Although proportion smaller than MT, this study provides organization system shares important similarities primates opens possibility computation mechanisms.
