- Optic and echo-acoustic flow interact in bats
Summary: Flying bats respond to both optic and echo-acoustic flow and rely on a weighted integration of the two cues for manoeuvring in light and dark environments.
- The brain behind straight-line orientation in dung beetles
Summary: Insights into the neural mechanisms underlying compass orientation in dung beetles are placed into the context of the mechanisms of other insects.
- Navigation and the developing brain
Summary: Spatial development in humans takes a decade or more to unfold, and involves tuning initial systems in response to changing motor capacities and environmental feedback.
- The insect central complex and the neural basis of navigational strategies
Summary: Neural circuits of the insect central complex are involved in guiding multiple navigation strategies, and the emerging core circuit for navigational decisions might provide an overarching framework of central-complex function.
- The internal maps of insects
Summary: Insect behaviour can be explained as a combination of path integration, vector memory and view memory, but what is the evidence that these geometric capabilities form an integrated map?
- Merging information in the entorhinal cortex: what can we learn from robotics experiments and modeling?
Summary: Grid cells related to path integration and vision are explained as modulo projections of different cortical activities. The entorhinal cortex appears as a generic merging tool building hash codes.
- Evidence for a southward autumn migration of nocturnal noctuid moths in central Europe
Summary: During autumn in central Europe, red underwing and large yellow underwing moths make a southward oriented nocturnal migration, although on foggy evenings, the latter species becomes disoriented.
- Carpenter ants use diverse antennae sampling strategies to track odor trails
Highlighted Article: High-resolution imaging of antennae reveals distinct patterns of sampling with non-redundant roles in odor tracking.
- Head-mounted sensors reveal visual attention of free-flying homing pigeons
Highlighted Article: A lightweight custom-made logger equipped with an inertial measurement unit (IMU) and GPS revealed head-gaze movement during homing flights in pigeons.
- Flying Drosophila melanogaster maintain arbitrary but stable headings relative to the angle of polarized light
Summary: Relative to celestial cues, fruit flies select unpredictable flight headings and maintain them with gradually increasing fidelity. This may be a general dispersal strategy for animals with no target destination.
