Book excerpt: All together, these studies provide strong evidence for the existence of multiple circuits between LGN and MT. Each pathway receives a different combination of M and P inputs and is uniquely suited to convey visual information with varying degrees of spatial and temporal resolution, contrast sensitivity, and color selectivity. Distinct cell types underlie many of these circuits, overcoming the lack of spatial compartmentalization of V1 outputs. Functional studies that can target these specialized cell types and circuits will be necessary to elucidate the contributions of each pathway to response properties in MT and, ultimately, to visual perception and behavior.
