Emergence of Functional Hierarchy in a Multiple Timescale Neural Network Model: A Humanoid Robot Experiment (2008, background): “Information processing in the visual cortex, investigated extensively in the study of visual perception, is thought to occur on multiple spatial scales [63–65].”
Coarse scales are sufficient for efficient categorization of emotional facial expressions: Evidence from neural computation (2010, methodology): “The mean brightness of the stimuli was normalized at 90.3 on a scale of 256 levels of gray for the LSF, HSF and BSF images.”
Developmental deficits in social perception in autism: the role of the amygdala and fusiform face area (2005, background): “Interestingly, in another recent study, Vuilleumier et al. (2003b) recently showed that the subcortical visual pathway is preferentially biased toward LSF information as opposed to HSF.”
The role of the amygdala in human fear: automatic detection of threat. (2005, background): “The low road concept and the supporting human data provided by Dolan’s group (Morris et al., 1998, 1999, 2001; Vuilleumier et al., 2003), as well as by our group (Öhman et al.”
Electrophysiological correlates of rapid spatial orienting towards fearful faces. (2004, neutral): “, 2003), a structure that is critically involved in fear processing and may receive direct inputs from subcortical pathways partly independent of striate cortex (LeDoux, 1996; Morris et al., 1999; Vuilleumier et al., 2003).”
Emotion processing and the amygdala: from a ‘low road’ to ‘many roads’ of evaluating biological significance (2010, positive): “Thus, coarse (that is, low-spatial-frequency) information from affective stimuli is thought to engage subcortical visual processing, consistent with findings that the amygdala (a collection of subcortical nuclei) is activated more strongly by emotional faces presented with low than high spatial freq”
Presentation and validation of the Radboud Faces Database (2010, background): “For example, studies on facial expression processing mainly use straight-gaze images with standardised expressions (e.g., Vuilleumier, Armony, Driver, & Dolan, 2003), whereas research on facial attention cues uses face images with varying gaze directions and head orientations (e.g., Loomis, Kelly,…”
Activation of the fusiform gyrus when individuals with autism spectrum disorder view faces (2004, background): “…face detection, involving a fast perceptual processing of highly salient stimuli by a network of areas comprising the superior colliculus, the amygdala, the thalamic lateral geniculate nucleus, the pulvinar and the striate cortex (Adolphs, 2002b; de Gelder et al., 1999; Vuilleumier et al., 2003).”
Distant influences of amygdala lesion on visual cortical activation during emotional face processing (2004, background): “Thus, seeing faces with fearful expressions produces greater activation of the face-responsive areas of the fusiform cortex than does seeing faces with neutral expression”
How brains beware: neural mechanisms of emotional attention. (2005, background): “However, we still need to elucidate the crucial sensory events [39, 47 ,58] and extent of cortical processing [23,48,57,59,70,71] necessary to activate the amygdala.”
Global-happy and local-sad: Perceptual processing affects emotion identification (2010, background): “Studies have shown differences in performance with emotional faces as a function of different spatial frequency content (Vuilleumier, Armony, Driver, & Dolan, 2003 ).”
