  • dynamic plasticity in phototransduction regulates seasonal changes in Color Perception
    Nature Communications, 2017
    Co-Authors: Tsuyoshi Shimmura, Ai Shinomiya, Tomoya Nakayama, Shoji Fukamachi, Masaki Yasugi, Eiji Watanabe, Takayuki Shimo
    Abstract:

    To cope with seasonal changes in the environment, organisms adapt their physiology and behavior. Although Color Perception varies among seasons, the underlying molecular basis and its physiological significance remain unclear. Here we show that dynamic plasticity in phototransduction regulates seasonal changes in Color Perception in medaka fish. Medaka are active and exhibit clear phototaxis in conditions simulating summer, but remain at the bottom of the tank and fail to exhibit phototaxis in conditions simulating winter. Mate preference tests using virtual fish created with computer graphics demonstrate that medaka are more attracted to orange-red-Colored model fish in summer than in winter. Transcriptome analysis of the eye reveals dynamic seasonal changes in the expression of genes encoding photopigments and their downstream pathways. Behavioral analysis of photopigment-null fish shows significant differences from wild type, suggesting that plasticity in Color Perception is crucial for the emergence of seasonally regulated behaviors. Animal Coloration and behavior can change seasonally, but it is unclear if visual sensitivity to Color shifts as well. Here, Shimmura et al. show that medaka undergo seasonal behavioral change accompanied by altered expression of opsin genes, resulting in reduced visual sensitivity to mates during winter-like conditions.

  • Seasonal changes in Color Perception
    General and Comparative Endocrinology, 2017
    Co-Authors: Tsuyoshi Shimmura, Ai Shinomiya, Tomoya Nakayama, Takashi Yoshimura
    Abstract:

    In temperate zones, organisms experience dynamic fluctuations in environment including changes in Color. To cope with such seasonal changes in the environment, organisms adapt their physiology and behavior. Although Color Perception has been believed to be fixed throughout life, there is increasing evidence for the alteration in opsin gene expression induced by environmental stimuli in a number of animals. Very recently, dynamic seasonal plasticity in Color Perception has been reported in the seasonally breeding medaka fish. Interestingly, seasonal changes in human Color Perception have also been reported. Therefore, plasticity of Color Perception, induced by environmental stimuli, might be a common phenomenon across various species.

  • Language , Learning , and Color Perception
    Current Directions in Psychological Science, 2004
    Co-Authors: United Kingdom, Emre Ozgen
    Abstract:

    People perceive Colors categorically. But what is the role of the environment (or nurture)—specifically, language—in Color Perception? The effects of language on the way people categorize and perceive Colors have been considered to be minimal, but recent evidence suggests that language may indeed change Color Perception. Speakers of languages with different Color-name repertoires show differences in the way they perceive Color. Research shows that categorical effects on Color percep- tion can be induced through laboratory training and suggests language can similarly change Color Perception through the mechanism of perceptual learning.
