Top-down modulation of visual feature processing: The role of the inferior frontal junction (2010, background): “Although top-down modulation is studied most often in the visual system (Duncan et al., 1997; Fuster, 1990; Gazzaley et al., 2005; Kastner et al., 1998), similar characteristics are found in the auditory (Hillyard et al., 1973), somatosensory (Seminowicz et al., 2004) and olfactory (Zelano et al.,…”
Executive Functions (2012, unknown): “For example, older adults are poor at inhibiting visual distractions (Darowski et al. 2008, Gazzaley et al. 2005) and auditory distractions (Alain & Woods 1999, Barr & Giambra 1990).”

Causal role of the prefrontal cortex in top-down modulation of visual processing and working memory (2011, background): “It is a bi-directional process, accomplished by differentially enhancing and suppressing neural activity in sensory cortical regions on the basis of the relevance of information to our goal”
