Many animal species rely on the Earth’s magnetic field during navigation, but where in brain information is processed still unknown. To unravel this, we manipulated natural at nest entrance of Cataglyphis desert ants and investigated how this affects relevant regions early compass calibration. We found that manipulating has profound effects neuronal plasticity two sensory integration centers. Magnetic manipulations interfere with a typical look-back behavior learning walks naive ants. Most importantly, structural analyses ants’ (central complex) memory centers (mushroom bodies) demonstrate visual learning. This suggests does not only serve as cue for navigation also global reference system crucial spatial formation. propose neural circuit into guidance networks ant brain. Taken together, our results provide an insight substrate insects.

The insect central complex appears to encode and process spatial information through vector manipulation. Here, we draw on recent insights into circuit structure fuse previous models of sensory-guided navigation, path integration memory. Specifically, propose that the allocentric encoding location provided by creates a spatially stable anchor for converging sensory signals is relevant in multiple behavioural contexts. reference frame given transforms goal direction demonstrate modelling it can enhance approach target noisy, cluttered environments or with temporally sparse stimuli. We further show same improve performance more navigational task route following. model suggests specific functional roles elements helps explain their high preservation across species.

Spatial memory helps animals to navigate familiar environments. In insects, spatial has extensively been studied in central place foragers such as ants and bees. However, if butterflies memorize a location remains unclear. Here, we conducted behavioural experiments test whether monarch (Danaus plexippus) can remember retrieve the of food source. We placed several visually identical feeders flight cage, with only one feeder providing sucrose solution. Across multiple days, individual predominantly visited rewarding feeder. Next, displaced salient landmark close which visual cue used relocate While occasional displacements were ignored by did not affect their decisions, systematic displacement both demonstrated that associated feeder's position. Altogether, show consolidate context foraging.

ABSTRACT Many animals exhibit innate behaviours, which are often interpreted as hard-wired, reflex-like responses, particularly in insects. Among these beacon-aiming—an approach towards dark areas or objects—is observed many animals; however, its functional significance remains unclear, and some ant species do not it. Here we show that one such species, Camponotus japonicus, the behaviour was triggered only under adverse substrate conditions, during crossing of liquid-covered surfaces, regardless locomotor patterns like walking swimming, mere presence water, when upside-down. Once initiated, beacon-aiming persists even normal demonstrated by ants transitioning from water-covered to dry substrates suitable for comfortable walking. This behavioural flexibility indicates is hard-wired but modulated internal states. Furthermore, changes states may serve adaptive decision-making, potentially allowing prepare future conditions. The isolated on a water-surrounded platform gradually established an attraction direction beacon before ultimately swimming These findings suggest regulated states, especially anxiety-like formed response past, imminent, predicted conditions ants.
