Classical conditioning of proboscis extension in honeybees (Apis mellifera).
TLDR
In a first series of experiments, acquisition was found to be very rapid, both in massing and in spaced trials; its associative basis was established by differential conditioning and by an explicitly unpaired control procedure (which produced marked resistance to acquisition in subsequent paired training); and both extinction and spontaneous recovery in massed trials were demonstrated.

TLDR
It is argued that these properties, although reflecting general characteristics of step-wise memory formation, are adapted to the species-specific adaptations in natural behavior, here to foraging at scattered and unreliable food sources.

The spectral input systems of hymenopteran insects and their receptor-based colour vision
TLDR
The predicted colour discriminability curves differ in their relative height of best discrim inability in the UV-blue or bluegreen area of the spectrum, indicating that relatively small differences in the S(λ) functions may have considerable effects on colour discriminatinginability.

Detection of coloured stimuli by honeybees: minimum visual angles and receptor specific contrasts
TLDR
The results suggest that green contrast can be utilized for target detection if target recognition has been established by means of the colour vision system.

TLDR
Data on associative learning and memory formation in honeybees is presented, emphasizing a comparative approach and believed that bees might be a useful model for studying cognitive faculties at a middle level of complexity.

Multiple sites of associative odor learning as revealed by local brain microinjections of octopamine in honeybees.
TLDR
The results suggest that the neuromodulator OA has the capacity of inducing associative learning in an insect brain and suggest the antennal lobes and the calyces as at least partially independent sites of associating odors that may contribute differently to learning and memory consolidation.

A digital three-dimensional atlas of the honeybee antennal lobe based on optical sections acquired by confocal microscopy
TLDR
A digital atlas of the glomeruli in the antennal lobe of the honeybee, Apis mellifera, accessible to the scientific community via the Internet is presented, a step towards interactive and freely accessible databases of animal brains.

The glomerular code for odor representation is species specific in the honeybee Apis mellifera
TLDR
It may be possible to create a functional atlas of the AL in which particular molecular receptive ranges are attributed to each glomerulus, based on measured glomerular responses to 30 different odors in the AL of honeybees.
