Most colour in nature arises from pigments, but the most brilliant, deeply saturated visual
signals have structural origins. These colours are generated from nanoscale structural …

Recent powerful tools for reconstructing connectomes using electron microscopy (EM) have
made outstanding contributions to the field of neuroscience. As a prime example, the …

The spatial and spectral properties of an eye can often be directly linked to the behaviour
and habitat of the animal. In a honey bee (Apis mellifera) society, the drones use the well …

The monarch butterfly, Danaus plexippus, is well known for its intimate association with
milkweed plants and its incredible multi-generational trans-continental migrations. However …

In both vertebrates and invertebrates, evidence supports separation of luminance
increments and decrements (ON and OFF channels) in early stages of visual processing (;); …

In dim light, scarcity of photons typically leads to poor vision. Nonetheless, many animals
show visually guided behavior with dim environments. We investigated the signaling …

The receptor mechanism for color vision has been extensively studied. In contrast, the circuit
(s) that transform (s) photoreceptor signals into color percepts to guide behavior remain (s) …

The functional significance of gene duplication is rarely addressed at the level of animal
behavior. Butterflies are excellent models in this regard because they can be trained and the …

Colour vision allows animals to use the information contained in the spectrum of light to
control important behavioural decisions such as selection of habitats, food or mates. Among …

Understanding how activity patterns in specific neural circuits coordinate an animal's
behavior remains a key area of neuroscience research. Genetic tools and a brain of …
