Integration of local features into global shapes: monkey and human FMRI studies. (2003, positive): “As in previousimages were acquired using a matrix of 256 256 (0.5 0.5 mm resolution, inversion recovery-rapid acquisition with relaxation en- studies (Kourtzi and Kanwisher, 2000, 2001), the order of presentation was counterbalanced so that trials from each condition, includ-hancement).”
Perceived Shape Similarity among Unfamiliar Objects and the Organization of the Human Object Vision Pathway (2008, background): “The overall LOC response depends on the perception of a coherent object shape (Grill-Spector et al., 1998a; Kourtzi and Kanwisher, 2000, 2001; Lerner et al., 2002; Hayworth and Biederman, 2006), and the shape representations in LOC are relatively invariant to image transformations such as size,…”
Hierarchical Modular Optimization of Convolutional Networks Achieves Representations Similar to Macaque IT and Human Ventral Stream (2013, background): “There is substantial evidence that the human brain solves this invariant object recognition challenge via a hierarchical cortical neuronal network called the ventral visual stream [13, 17], which has highly homologous areas in non-human primates [19, 9].”
The fusiform face area: a cortical region specialized for the perception of faces (2006, methodology): “The best current method for approaching this problem with fMRI is fMR adaptation (Grill-Spector et al. 1999; Kourtzi & Kanwisher 2001; Koutstaal et al. 2001), in which the blood oxygenation level dependent (BOLD) response to two (or more) stimuli in a given region of the brain is lower when they…”
The human visual cortex. (2004, background): “Several recent studies indicate that object-selective regions in the ventral stream represent shapes rather than contours or object features (Andrews et al. 2002, Kourtzi & Kanwisher 2001b, Lerner et al. 2002).”
Divide and conquer: A defense of functional localizers (2006, background): “, (Friston et al., in press; Kourtzi and Kanwisher, 2001) compared the effects of stimulus shape (same versus different) and depth (same versus different) on the response of the LOC fROI.”
Capacity limit of visual short-term memory in human posterior parietal cortex (2004, methodology): “Each fMRI run included seven iterations of each of the seven trial types (six set sizes and a non-event trial with no visual or auditory stimuli presented), with the order of trial type counterbalance”
Specificity of Action Representations in the Lateral Occipitotemporal Cortex (2006, background): “Disciplines Psychology This journal article is available at ScholarlyCommons: https://repository.upenn.edu/psychology_papers/22 Specificity of Action Representations in the Lateral Occipitotemporal Cortex Joseph W. Kable* and Anjan Chatterjee”
High-for-Low and Low-for-High: Efficient Boundary Detection from Deep Object Features and Its Applications to High-Level Vision (2015, background): “However, psychological studies suggest that when a human observer perceives boundaries, object level reasoning is used [13, 25, 17].”
Multisensory visual–tactile object related network in humans: insights gained using a novel crossmodal adaptation approach (2009, methodology): “…specialization in vision, for example, for convergence of diVerent cues underlying a visual stimulus, shape processing (Kourtzi et al. 2003; Kourtzi and Kanwisher 2000, 2001), face encoding (Winston et al. 2004; Sigala and Rainer 2007), and the integration of color and motion (Self and…”
The cortical basis of visual scene processing (2005, background): “…Kushnir, Edelman, Avidan, Itzchak, & Malach, 1999; Grill-Spector, Kushnir, Edelman, Itzchak, & Malach, 1998; Henson, Shallice, & Dolan, 2000; Kourtzi & Kanwisher, 2001; Schacter & Buckner, 1998; Stern et al., 1996; van Turennout, Bielamowicz, & Martin, 2003; Vuilleumier, Henson, Driver, &…”
Saliency Detection: A Boolean Map Approach (2013, background): “Neuroscience findings also show that certain responses in monkey and human brains involved in shape perception are critically dependent on figure-ground assignment [2, 26], indicating that this process may start early in the visual system.”
fMRI-adaptation reveals dissociable neural representations of identity and expression in face perception. (2004, background): “Such immediate repetition induces robust fMRI adaptation (Epstein et al. 2003; Kourtzi and Kanwisher 2001).”
