  1. Issues When Applying Structuralism to Biology.Angella Yamamoto - manuscript
    *Presented at the Western Canadian Philosophical Association Conference 2019 at the University of Lethbridge in Lethbridge, Alberta.* -/- This paper discusses some issues that arise when applying structural realism to biology. I begin by reviewing Katherine Brading’s version of structural realism with a hierarchy with proliferation of models.1 I then attempt to apply Brading’s structural realism to a biological example. This biological example suggests an issue with the use of shared structure. In response, I suggest the use of relevant relations (...)

  3. Neural Correlates of Color-Selective Metacontrast in Human Early Retinotopic Areas.Kiyohiro Maeda, Hiroki Yamamoto, Masaki Fukunaga, Masahior Umeda, Chuzo Tanaka & Yoshimichi Ejima - 2010 - Journal of Neurophysiology 104:2291-2301.
    Metacontrast is a visual illusion in which the visibility of a target stimulus is virtually lost when immediately followed by a nonoverlapping mask stimulus. For a colored target, metacontrast is color-selective, with target visibility markedly reduced when the mask and target are the same color, but only slightly reduced when the colors differ. This study investigated neural correlates of color-selective metacontrast for cone-opponent red and green stimuli in the human V1, V2, and V3 using functional magnetic resonance imaging. Neural activity (...)

  4. Activity in early visual areas predicts interindividual differences in binocular rivalry dynamics.Hiroyuki Yamashiro, Hiroki Yamamoto, Hiroaki Mano, Masahiro Umeda, Toshihiro Higuchi & Jun Saiki - 2014 - Journal of Neurophysiology 111:1190-1202.
    When dissimilar images are presented to the two eyes, binocular rivalry (BR) occurs, and perception alternates spontaneously between the images. Although neural correlates of the oscillating perception during BR have been found in multiple sites along the visual pathway, the source of BR dynamics is unclear. Psychophysical and modeling studies suggest that both low- and high-level cortical processes underlie BR dynamics. Previous neuroimaging studies have demonstrated the involvement of high-level regions by showing that frontal and parietal cortices responded time locked (...)
