BMC Neurosci
. 2023 Dec;
24(1):67.
PMID: 38097940
Background: The behavioral photosensitivity of animals could be quantified via the optomotor response (OMR), for example, and the luminous efficiency function (the range of visible light) should largely rely on...

PMID: 37107554
Somatolactin alpha (SLα) is a fish-specific hormone involved in body color regulation. The growth hormone (GH) is another hormone that is expressed in all vertebrates and promotes growth. These peptide...

PMID: 36301532
Purpose: Ablation of short single cones (SSCs) expressing short-wavelength-sensitive opsin (SWS1) is well analyzed in the field of regenerative retinal cells. In contrast with ablation studies, the phenomena caused by...

PMID: 34780539
The three-chamber experiment, in which one test animal can choose between two animals placed in physically inaccessible compartments, is a widely adopted strategy for studying sexual preference in animals. Medaka,...

PMID: 34386255
Various procedures have been adopted to investigate spectral sensitivity of animals, e.g. absorption spectra of visual pigments, electroretinography, optokinetic response, optomotor response (OMR) and phototaxis. The use of these techniques...

PMID: 32903371
Common ancestors of vertebrates had four types of cone opsins: short-wavelength sensitive 1 (SWS1), SWS2, rhodopsin 2 (RH2), and long-wavelength sensitive (LWS) types. Whereas fish and birds retain all the...

PMID: 30804415
Tandem gene duplication has led to an expansion of cone-opsin repertoires in many fish, but the resulting functional advantages have only been conjectured without empirical demonstration. Medaka (Oryzias latipes and...

PMID: 29921705
The optomotor response (OMR) is a locomotor behavior of animals that is induced by moving repetitive visual stimuli. This characteristic helps animals particularly when stabilizing and maintaining position in schools...

PMID: 29447852
Colour vision is often essential for animals. Fine discrimination of colours enhances the ability of animals to find food, predators, or mating partners. Using two colour variants of medaka (Oryzias...

PMID: 28871081
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....
