The main functions of the lobe systems based on work by Young and his colleagues (Messenger, 1979, Young, 1961, Young, 1971, Young, 1974, Young, 1976, Young, 1977, Young, 1979, Boycott and Young, 1955, Boycott and Young, 1957, Wells and Wells, 1957, Nixon and Young, 2003). Supraoesophageal mass includes basal lobe and optic track complexes. Suboesophageal mass consists of the brachial lobe, pedal lobe, magnocellular lobe, and palliovisceral lobe complexes. * indicates that the lobe is further divided into the left and right lobe. Ψ indicates a further sub-division of the anterior chromatophore lobes into dorsal and ventral halves.
