title = {Anatomical basis of sun compass navigation I: the general layout
of the monarch butterfly brain.},
journal = {J Comp Neurol},
year = {2012},
volume = {520},
pages = {1599--1628},
abstract = {Each fall, eastern North American monarch butterflies (Danaus plexippus)
use a time-compensated sun compass to migrate to their overwintering
grounds in central Mexico. The sun compass mechanism involves the
neural integration of skylight cues with timing information from
circadian clocks to maintain a constant heading. The neuronal substrates
for the necessary interactions between compass neurons in the central
complex, a prominent structure of the central brain, and circadian
clocks are largely unknown. To begin to unravel these neural substrates,
we performed 3D reconstructions of all neuropils of the monarch brain
based on anti-synapsin labeling. Our work characterizes 21 well-defined
neuropils (19 paired, 2 unpaired), as well as all synaptic regions
between the more classically defined neuropils. We also studied the
internal organization of all major neuropils on brain sections, using
immunocytochemical stainings against synapsin, serotonin, and ?-aminobutyric
acid. Special emphasis was placed on describing the neuroarchitecture
of sun-compass-related brain regions and outlining their homologies
to other migratory species. In addition to finding many general anatomical
similarities to other insects, interspecies comparison also revealed
several features that appear unique to the monarch brain. These distinctive
features were especially apparent in the visual system and the mushroom
body. Overall, we provide a comprehensive analysis of the brain anatomy
of the monarch butterfly that will ultimately aid our understanding
of the neuronal processes governing animal migration.},

title = {Central neural coding of sky polarization in insects.},
journal = {Philos Trans R Soc Lond B Biol Sci},
year = {2011},
volume = {366},
pages = {680--687},
abstract = {Many animals rely on a sun compass for spatial orientation and long-range
navigation. In addition to the Sun, insects also exploit the polarization
pattern and chromatic gradient of the sky for estimating navigational
directions. Analysis of polarization-vision pathways in locusts and
crickets has shed first light on brain areas involved in sky compass
orientation. Detection of sky polarization relies on specialized
photoreceptor cells in a small dorsal rim area of the compound eye.
Brain areas involved in polarization processing include parts of
the lamina, medulla and lobula of the optic lobe and, in the central
brain, the anterior optic tubercle, the lateral accessory lobe and
the central complex. In the optic lobe, polarization sensitivity
and contrast are enhanced through convergence and opponency. In the
anterior optic tubercle, polarized-light signals are integrated with
information on the chromatic contrast of the sky. Tubercle neurons
combine responses to the UV/green contrast and e-vector orientation
of the sky and compensate for diurnal changes of the celestial polarization
pattern associated with changes in solar elevation. In the central
complex, a topographic representation of e-vector tunings underlies
the columnar organization and suggests that this brain area serves
as an internal compass coding for spatial directions.},

title = {Behavioural and physiological mechanisms of polarized light sensitivity
in birds.},
journal = {Philos Trans R Soc Lond B Biol Sci},
year = {2011},
volume = {366},
pages = {763--771},
abstract = {Polarized light (PL) sensitivity is relatively well studied in a large
number of invertebrates and some fish species, but in most other
vertebrate classes, including birds, the behavioural and physiological
mechanism of PL sensitivity remains one of the big mysteries in sensory
biology. Many organisms use the skylight polarization pattern as
part of a sun compass for orientation, navigation and in spatial
orientation tasks. In birds, the available evidence for an involvement
of the skylight polarization pattern in sun-compass orientation is
very weak. Instead, cue-conflict and cue-calibration experiments
have shown that the skylight polarization pattern near the horizon
at sunrise and sunset provides birds with a seasonally and latitudinally
independent compass calibration reference. Despite convincing evidence
that birds use PL cues for orientation, direct experimental evidence
for PL sensitivity is still lacking. Avian double cones have been
proposed as putative PL receptors, but detailed anatomical and physiological
evidence will be needed to conclusively describe the avian PL receptor.
Intriguing parallels between the functional and physiological properties
of PL reception and light-dependent magnetoreception could point
to a common receptor system.},
