✦ Synopsis
The projection of Octopus vulgaris motor chromatophore fibres on the body surface is revealed by sectioning the brain nerves. The denervated areas remain pMe and, therefore, allow to determine the pattern of nerve projection. Ten of the approximately 30 nerves leaving the O. vulgaris brain contain chromatophore fibres. Their areas of colour control are well defined, and do not overlap.
nerves cut under the microscope after opening of the head cartilage b y a median line incision. The cephalopods were allowed to recover in a stream of flowing sea water for some minutes after the operation. The location of the nerve section was checked several days after the operation on the perfused individual (3.5 % glutaraldehyde in sea water).
