“…More recently, the context has been revealed as an important source of top-down control over processing of multisensory information. While some studies demonstrated the role of long-term experience and learning (e.g., Froyen et al, 2009;Stevenson and Wallace, 2013;Barenholtz et al, 2014;Ten Oever et al, 2014;Matusz et al, 2015b), many focused on effects operating at shorter timescales, such as expectations and/or experiences built over the course of a single experimental session (e.g., Murray et al, 2004Murray et al, , 2005von Kriegstein and Giraud, 2006;Meylan and Murray, 2007;Rosenblum et al, 2007;Beierholm et al, 2009;Powers et al, 2009;Barakat et al, 2013;Chandrasekaran et al, 2009;Thelen et al, 2012Thelen et al, , 2014Matusz et al, 2015c;Altieri et al, 2015), or even across a pair of successive experimental trials Murray et al 2009;King et al 2012;Sarmiento et al, 2015). Considered together, the overwhelming evidence for the importance of context-based factors for stimulus processing across the senses and the concomitant limited existing data on the ACOP makes it plausible that irrelevant sounds activate the visual cortex in some contexts but not in others.…”
