Beyond Skip Connections: Top-Down Modulation for Object Detection (2016, background): “There is strong evidence of such top-down context, feedback and lateral processing in the human visual pathway [7, 13, 15, 25, 28, 30, 31, 37, 53, 54]; wherein, the topdown signals are responsible for modulating low-level features [13, 15, 37, 53, 54] as well as act as attentional mechanism for sele”
Deep Networks with Internal Selective Attention through Feedback Connections (2014, background): “Regarding the attentional phase, feedback connections are known to play important roles, such as in feature grouping [34], in differentiating a foreground from its background, (especially when the foreground is not highly salient [35]), and perceptual filling in [36].”
Human Pose Estimation with Iterative Error Feedback (2015, background): “Neuroscience models of the human brain suggest that feedforward connections act as information carriers while numerous feedback connections act as modulators or competitive inhibitors to aid feature grouping [14], figure-ground segregation [16] and object recognition [46].”
Adult-born neurons facilitate olfactory bulb pattern separation during task engagement (2018, positive): “These centrifugal projections are suggested to be sensitive to brain states (Gilbert and Sigman, 2007; Rothermel and Wachowiak, 2014).”
Predictive Feedback Can Account for Biphasic Responses in the Lateral Geniculate Nucleus (2009, background): “, and adapt early level signals according to different sensory or behavioral conditions”
Potassium channels control the interaction between active dendritic integration compartments in layer 5 cortical pyramidal neurons. (2013, positive): “…dendritic tuft input drives high-frequency AP burst firing suggests that topdown influences such as attention, expectation, and action command (Gilbert and Sigman, 2007; Gregoriou et al., 2009; Hupe et al., 1998; Xu et al., 2012) will dramatically increase the salience of L5B pyramidal neuron…”
Feedback Network for Image Super-Resolution (2019, background): “In cognition theory, feedback connections which link the cortical visual areas can transmit response signals from higher-order areas to lower-order areas [17, 9].”
The Normalization Model of Attention (2009, background): “While we have considered spatial and feature-based forms of attentional selection, there is mounting evidence that attention can operate on more complex properties of stimuli, such as contours, surfaces, and whole objects (Gilbert and Sigman, 2007; Khoe et al., 2005; Mitchell et al., 2004; Qui et al”
The functional organization of the barrel cortex. (2007, background): “…plasticity, it is also becoming increasingly clear that the functional operation of cortical circuits in behaving animals is under rapid and strong top-down control, generating highly flexible adaptive sensory processing within the same hard-wired neuronal networks (Gilbert and Sigman, 2007).”
Interactive specialization: a domain-general framework for human functional brain development? (2011, positive): “As mentioned earlier, the prefrontal cortex is generally considered to have a special role during development in childhood and skill acquisition in adults (Thatcher, 1992; Gilbert and Sigman, 2007).”
