Metacontrast, target recovery, and the magno- and parvocellular systems: A reply to the perspective

In macaques, it was previously known that a majority of 4B neurons projecting to MT were of the spiny stellate type (that receives pure magnocellular input), but the exact connection patterns and types of pyramidal cells projecting to MT were not fully understood.\n However, unless one can show that all the color-dependent modulation of metacontrast strength is due to correlated color-dependent modulation of parvocellular responses, Skottun's (2004) analysis does not rule out the role of the magnocellular system.
