ABSTRACT Air-cushioned spheres are widely used as treadmills to study behavioural and neurophysiological questions in numerous species. We describe an improved spherical treadmill design that reliably registers the path and walking behaviour of an animal walking on top of the sphere. The simple and robust set-up consists of a very light hollowed styrofoam ball supported by an air stream in a hollow half sphere and can be used indoors and outdoors. Two optical mouse sensors provided with lenses…

Navigation of a Freely Walking Fruit Fly in Infinite Space Using a Transparent Omnidirectional Locomotion Compensator (TOLC)

The proposed Transparent Omnidirectional Locomotion Compensator (TOLC) for a freely walking fruit fly without tethering enables its navigation in infinite space and will offer a unique opportunity to investigate longitudinal studies of a wide range of behavior in an unrestricted walking Drosophila.

All current evidence suggests that Cataglyphis does not compute a vector in 3-D: path integration seems to operate exclusively in the horizontal plane, and the mechanisms by which ants may measure slopes still await clarification.

A motion compensation treadmill for untethered wood ants (Formica rufa): evidence for transfer of orientation memories from free-walking training

It is demonstrated that ants are able to transfer associative and navigational memories from classical maze and arena contexts to the treadmill, demonstrating the possibility to study navigational behaviour over ecologically relevant durations in precisely controlled environments.

Bumblebees navigate using path integration while walking

It is reported that the bumblebee, Bombus terrestris, uses path integration while walking over short distances in an indoor arena, and exhibits systematic search patterns when home vectors failed to lead them accurately back to the nest.

Transfer of orientation memories in untethered wood ants (Formica rufa) from walking in an arena to walking on a motion compensation treadmill

A motion compensating treadmill for wood ants is developed and validated which opens new perspectives to study insect navigation behaviour in a fully controlled manner over ecologically relevant durations, bridging the gap between natural and highly controlled laboratory experiments.

The Antarium: A Reconstructed Visual Reality Device for Ant Navigation Research

The Antarium is a large projection device with 20,000 UV-Blue-Green LEDs that allows us to present tethered ants with views of their natural foraging environment and can be used to investigate the dynamics of navigational guidance and the neurophysiological basis of ant navigation in natural visual environments.

The role of attractive and repellent scene memories in ant homing (Myrmecia croslandi)

It is concluded that the ants' behaviour at release sites is exclusively driven by what they currently see and not by information on expected outcomes of their behaviour; and that navigating ants might continuously integrate attractive and repelling visual memories.

The orientation of walking honeybees in odour fields with small concentration gradients

The behaviour of walking honeybees in small gradient odour fields was investigated by means of a simulation technique and revealed that honeybees are capable of finding odour sources in the absence of optical cues and with concentration gradients too small to allow tropotactic or klinotactic orientation.

Visual navigation in desert ants Cataglyphis fortis: are snapshots coupled to a celestial system of reference?

Investigation of the use of landmark information and a celestial system of reference for nest location by training desert ants shows that, in the ants' visual snapshot memory, a Memorized landmark scene can temporarily be decoupled from a memorized celestial systemof reference.

Visual navigation in insects: coupling of egocentric and geocentric information

The flexible use of vectors, snapshots and landmark-based routes suffices to interpret the insect's behaviour and the cognitive-map approach in particular and the representational paradigm in general are discussed.

Stationary and dynamic responses during visual edge fixation by walking insects

In this investigation, free moving animals with head movements unrestricted also show optomotor responses when no slip speed between animal and surround is present.

This work experimentally manipulates ants' outbound trajectories to elucidate the ant's way of computing its mean home vector and shows that the ants solve this path integration problem not by performing a true vector summation but by employing a computationally simple approximation.

The locomotory behaviour of workers of 12 ant species belonging to four different genera was studied by filming individuals walking on smoked-glass plates and subsequent multivariate analyses of footfall positions and walking kinematics revealed a set of constant features characterizing ant locomotion.

Calibration processes in desert ant navigation: vector courses and systematic search

It is suggested that the ants cannot learn separate inbound and outbound vectors, and that the recalibration of the vector and the modification of the search geometry are fast and flexible processes occurring whenever the ant experiences a mismatch between the stored and actual states of its path integrator.

Insect navigation: use of maps or Ariadne's thread ?

This chapter discusses how an animal using the mental analogue of a topographical map can episodically take a positional fix, i.e. rely on information collected on site.
