""One of the most well-studied cortical visual areas in primates is the middle temporal complex (area MT+). Despite a large and comprehensive selleck products body of literature, the way that MT+ represents visual space is debated. Area MT in the macaque monkey, and its human homolog hMT+, has been shown to represent positions coarsely in a retinotopic manner (Gattass and Gross, 1981; Bumetanide Huk et?al., 2002; Wandell et?al., 2007). Detailed mapping procedures revealed up to four retinotopic maps that collectively form the MT+ complex in humans (Dukelow et?al., 2001; Amano et?al., 2009; Kolster et?al., 2010). Recently, some researchers have proposed that MT+ contributes to stable perception across eye movements by representing object locations in a world-centered, or spatiotopic, coordinate frame (Melcher and Morrone, 2003; d��Avossa et?al., 2007; Ong et?al., 2009; Crespi et?al., 2011). Other researchers have found evidence for only retinotopic, and not spatiotopic, coordinate frames in MT+ (Gardner et?al., 2008; Morris et?al., 2010; Hartmann et?al., 2011; Ong and Bisley, 2011; Au et?al., 2012; Golomb and Kanwisher, 2012), a difference that may be due to the location of covert visual attention (Gardner et?al., 2008; Crespi et?al., 2011). Most of these studies investigated spatial representations in MT+ at a relatively coarse spatial scale. However, during routine activities, such as navigating around obstacles or manipulating objects, the visual system��s ability to localize objects on a fine spatial scale defines our ability to interact MEK inhibitor successfully with the world. At a population level, MT+ represents fine-scale spatial information, discriminating position shifts of one-third of a degree of visual angle or less (Fischer et?al., 2011). At these fine scales, a number of visual phenomena show remarkable dissociations between the perceived position of an object and its retinal or spatial position; for example, motion in the visual field can shift the perceived positions of stationary or moving objects (Fr?hlich, 1923; Ramachandran and Anstis, 1990; De Valois and De Valois, 1991; Nijhawan, 1994; Whitney and Cavanagh, 2000; Krekelberg and Lappe, 2001; Whitney, 2002; Eagleman and Sejnowski, 2007). Disrupting activity in area MT+ by transcranial magnetic stimulation (TMS) reduces these motion-induced mislocalization illusions (McGraw et?al., 2004; Whitney et?al., 2007; Maus et?al., 2013).
