Deep Networks with Internal Selective Attention through Feedback Connections (2014, background): “[37] supports the idea that top-down projections from prefrontal cortex play an important role in object recognition by quickly extracting low-level spatial frequency information to provide an initial guess about potential categories, forming a top-down expectation that biases recognition.”
How does the brain solve visual object recognition? (2012, neutral): “These higher agents thus glimpse the ‘‘forest for the trees’’ (e.g., Bar et al., 2006) and in turn direct the lowest levels (the foot soldiers) on how to optimize processing of this weak sensory evidence, presumably to help the higher agents (e.g., IT).”
Brain-Like Object Recognition with High-Performing Shallow Recurrent ANNs (2019, background): “(3) Recurrent: while core object recognition was originally believed to be largely feedforward because of its fast time scale [6], it has long been suspected that recurrent connections must be relevant for some aspects of object perception [20, 1, 43], and recent studies have shown their role even a”
Let's face it: It's a cortical network (2008, background): “Consistent with a recent study, which showed that the prefrontal cortex generates predictions that influence object processing in extrastriate regions (Bar et al., 2006), the model also predicts that an indeterminate facial input will increase the top-down connectivity from the OFC to the FG.”
Intergroup Perception and Cognition: An Integrative Framework for Understanding the Causes and Consequences of Social Categorization (2017, background): “…example, in support of this framework, faces expressing anger and fear have been found to enhance activity in the amygdala, insula, and OFC, as noted earlier, and these activations are believed to shape high-level visual and cognitive processes (Bar et al., 2006; Freeman, Ambady, & Holcomb, 2010).”
Sequence of information processing for emotions based on the anatomic dialogue between prefrontal cortex and amygdala (2007, background): “…2000), its feedforward projections to orbitofrontal cortex may convey the affective significance of external sensory stimuli, consistent with the involvement of orbitofrontal cortex in rapid perception and reward contingencies (e.g., Rolls, 1996; Tremblay and Schultz, 1999; Bar et al., 2006).”
Monkey to human comparative anatomy of the frontal lobe association tracts. (2012, background): “…topedown modulation of visual processing in general (i.e., not restricted to processing emotional value of visual percepts) (Pins and Ffytche, 2003; Bar et al., 2006), including topedown amplification of visual percepts characteristic of conscious visual processing (Dehaene et al., 2006) and…”
Analysis by Synthesis: A (Re-)Emerging Program of Research for Language and Vision (2010, methodology): “One example of how the AxS idea might work in visual object recognition is provided by the work of Moshe Bar (Bar et al. 2006, Bar 2007, Kveraga et al. 2007).”
Act-In: An integrated view of memory mechanisms (2014, background): “That is why more recent models of perception accept the existence of top–down effects (Bar, 2004; Bar et al., 2006) which facilitate this correspondence.”
The Limits of Feedforward Vision: Recurrent Processing Promotes Robust Object Recognition when Objects Are Degraded (2012, background): “In accordance with this latter view, recent reports have cited recurrent processing effects occurring as early as 100– 150 msec (Koivisto, Railo, Revonsuo, Vanni, & Salminen- Vaparanta, 2011; Roland, 2010; Bar et al., 2006; Foxe & Simpson, 2002; Lamme & Roelfsema, 2000).”
Emotions Emerge from More Basic Psychological Ingredients: A Modern Psychological Constructionist Model (2013, methodology): “Consistent with this interpretation, the medial (m) OFC and the rest of the ventromedial prefrontal cortex (of which mOFC is a part) is thought to help the brain make predictions about the affective meaning of sensations (e.g., visual sensations; Bar et al., 2006) using representations of prior expe”
