Resumen:
ABSTRACT
The Decapoda is the largest order of crustaceans,
some 10,000 species having been described to date.
The order includes shrimps, lobsters, crayfishes, and
crabs. Most of these are highly visual animals that display
complex visually guided behaviors and, consequently,
large areas of their nervous systems are
dedicated to visual processing. However, our knowledge
of the organization and functioning of the visual nervous
system of these animals is still limited. Beneath the
retina lie three serially arranged optic neuropils connected
by two chiasmata. Here, we apply dye tracers in
different areas of the retina or the optic neuropils to
investigate the organization of visual space maps in the
optic neuropils of the brachyuran crab Chasmagnathus
granulatus. Our results reveal the way in which the visual
space is represented in the three main optic neuropils
of a decapod. We show that the crabs optic
chiasmata are oriented perpendicular to each other, an
arrangement that seems to be unique among malacostracans.
Crabs use retinal position in azimuth and elevation
to categorize visual stimuli; for instance, stimuli
moving above or below the horizon are interpreted as
predators or conspecifics, respectively. The retinotopic
maps revealed in the present study create the possibility
of relating particular regions of the optic neuropils
with distinct behavioral responses elicited by stimuli
occurring in different regions of the visual field. J.
