Photoreactions of cephalopod rhodopsin
Vision Research, 1981Abstract In the cephalopod rhodopsin system, two new photoproducts from alkaline metarhodopsin were found. One was slowly converted to rhodopsin in the dark and called pseudo-rhodopsin. It could be photoconverted to the other, pseudo-metarhodopsin. This resulted in a photosteady state mixture in the light. Absorbance spectra of both pigments depended

Components of the cephalopod electroretinogram
Experimental Eye Research, 1975Abstract The electroretinogram of the cephalopod Sepiola atlantica has been studied using microelectrode recording of extracellular potentials in the retina. Differential-depth studies of the photoresponse to a very short light flash reveal a “fast” component which is prominent in the outer segments of the photoreceptor cells, and a “slow” component ...

The organization of a cephalopod ganglion
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1972Abstract The stellate ganglion of cephalopods is sharply divided into a ventral part containing only large cells and a dorsal part where there are also microneurons (amacrine cells). Axons proceed from the larger cells of the ganglion to the stellar nerves in distinct dorsal and ventral roots, which join as they leave the ganglion ...

Cephalopod lens proteins have been studied by electrophoresis, immunological methods and ultracentrifugal sedimentation. The most important result is the systematic order difference between the decapods and octopods, as revealed by their electrophoretic eye lens patterns and their corresponding serological cross-reactions.

Neurovenous tissues in cephalopods
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1970Abstract The juxta-ganglionic tissues of cephalopods consist of tubes containing columns of cells and nerve fibres. They arise in or near ganglia and pass to endings in the walls of veins or the organ of the anterior chamber of the eye.

Cephalopods are generally regarded as the most intelligent group among the invertebrates. Despite their popularity, relatively little is known about the range and function of their cognitive abilities. This book fills that gap, accentuating the varied and fascinating aspects of cognition across the group.
