Peptidergic regulation of chromatophore function in the European cuttlefish Sepia officinalis
Color patterning in cephalopod molluscs involves activation of a peripheral chromatophore system that is under neuromuscular control. The complex behavior of individual chromatophores is mediated by a specific set of muscles, the chromatophore muscles, that receive direct innervation from the central nervous system. To date, glutamate is the only excitatory transmitter that has been proposed to...
متن کاملPeripheral innervation patterns and central distribution of fin chromatophore motoneurons in the cuttlefish Sepia officinalis.
Body patterning behavior in unshelled cephalopod molluscs such as squid, octopuses, and cuttlefish is the ability of these animals to create complex patterns on their skin. This behavior is generated primarily by chromatophores, pigment-containing organs that are directly innervated by central motoneurons. The present study focuses on innervation patterns and location of chromatophore motoneuro...
متن کاملThe Dermal Chromatophore Unit
Rapid color changes of amphibians are mediated by three types of dermal chromatophores, xanthophores, iridophores, and melanophores, which comprise a morphologically and physiologically distinct structure, the dermal chromatophore unit. Xanthophores, the outermost element, are located immediately below the basal lamella. Iridophores, containing light-reflecting organelles, are found just beneat...
متن کاملNeural regulation of a complex behavior: body patterning in cephalopod molluscs.
Unshelled cephalopods have a remarkable ability to alter their appearance, using textural, postural, and chromatic elements to generate a myriad of body patterns. Of the unshelled cephalopods, it is generally acknowledged that cuttlefish express the most detailed and widest range of body patterns, including static and dynamic patterns. In this paper we present data on the neuronal mechanisms un...
متن کاملBehavioural responses of juvenile cuttlefish (Sepia officinalis) to local water movements
Physiological studies have shown that the epidermal head and arm lines in cephalopods are a mechanoreceptive system that is similar to the fish and amphibian lateral lines (Budelmann BU, Bleckmann H. 1988. A lateral line analogue in cephalopods: Water waves generate microphonic potentials in the epidermal head lines of Sepia officinalis and Lolliguncula brevis. J. Comp. Physiol. A 164:1–5.); ho...
