Daphnids are freshwater crustaceans used in toxicity tests. Although lethality and
immobilisation are the most commonly used endpoints in those tests, more sensitive …

The use of vision to coordinate behavior requires an efficient control design that stabilizes
the world on the retina or directs the gaze towards salient features in the surroundings. With …

Whatever theory may be advanced to explain diurnal migration, the underlying reactions
involved must be demonstrated conc-sively in the laboratory before the explanation can be …

In malacostracan crustaceans and insects three nested optic lobe neuropils are linked by
two successive chiasmata that reverse and then reverse again horizontal rows of retinotopic …

Giant motion-sensitive tangential neurons in the lobula plate are thought to be cardinal
elements in the oculomotor pathways of flies. However, these large neurons do not …

Developmental and evolutionary data from vertebrates are beginning to elucidate the origin
of the sensorimotor pathway that links gravity and motion detection to image-stabilizing eye …

We reveal the neuroanatomy of the optic ganglia and central brain in the water flea Daphnia
magna by use of classical neuroanatomical techniques such as semi-thin sectioning and …

Daphnia are keystone species of freshwater habitats used as model organisms in ecology
and evolutionary biology. Their small size, wide geographic distribution, and sensitivity to …

In insects, head movements are mediated by neck muscles supplied by nerves originating in
the brain and prothoracic ganglion. Extracellular recordings of the nerves demonstrate units …

The freshwater crustacean Daphnia is well known for its phenotypic plasticity, in which
environmental cues are perceived by the nervous system and transformed into phenotypic …
