The jawless fish that were ancestral to all living vertebrates had four spectral cone types that
were probably served by chromatic-opponent retinal circuits. Subsequent evolution of …

Synaptic interactions to extract information about wavelength, and thus color, begin in the
vertebrate retina with three classes of light-sensitive cells: rod photoreceptors at low light …

Animal colour vision is based on comparing signals from different photoreceptors. It is
generally assumed that processing different spectral types of photoreceptor mainly serves …

Visual stimuli can evoke complex behavioral responses, but the underlying streams of
neural activity in mammalian brains are difficult to follow because of their size. Here, I review …

Retinal degenerations are a heterogeneous group of diseases characterized by death of
photoreceptors and progressive loss of vision. Retinal degenerations are a major cause of …

The use of spectral information in natural light to inform behaviour is one of the oldest and
most fundamental abilities of visual systems. It long-predates animals' venture onto the land …

In recent years, a rapidly increasing number of scientific papers have been published that
utilize zebrafish (Danio rerio) as an alternative model organism in the study of a wide range …

Visual system development is a highly complex process involving coordination of
environmental cues, cell pathways, and integration of functional circuits. Consequently, a …

In vertebrate vision, the tetrachromatic larval zebrafish permits non-invasive monitoring and
manipulating of neural activity across the nervous system in vivo during ongoing behavior …

Unlike mammals, zebrafish regenerate in response to retinal damage. Because microglia
are activated by retinal damage, we investigated their role during regeneration following …
