TLDR
The data suggest that the many parallel channels of intrinsic neurons may each process different aspects of sensory input information within the mushroom body's calyx, which is particularly large in social Hymenoptera.Abstract:
The mushroom bodies are regions in the insect brain involved in processing complex multimodal information. They are composed of many parallel sets of intrinsic neurons that receive input from and transfer output to extrinsic neurons that connect the mushroom bodies with the surrounding neuropils. Mushroom bodies are particularly large in social Hymenoptera and are thought to be involved in the control of conspicuous orientation, learning, and memory capabilities of these insects. The present account compares the organization of sensory input to the mushroom body's calyx in different Hymenoptera. Tracer and conventional neuronal staining procedures reveal the following anatomic characteristics: The calyx comprises three subdivisions, the lip, collar, and basal ring. The lip receives antennal lobe afferents, and these olfactory input neurons can terminate in two or more segregated zones within the lip. The collar receives visual afferents that are bilateral with equal representation of both eyes in each calyx. Visual inputs provide two to three layers of processes in the collar subdivision. The basal ring is subdivided into two modality-specific zones, one receiving visual, the other antennal lobe input. Some overlap of modality exists between calycal subdivisions and within the basal ring, and the degree of segregation of sensory input within the calyx is species-specific. The data suggest that the many parallel channels of intrinsic neurons may each process different aspects of sensory input information.read more

Octopamine-Like Immunoreactivity in the Honey Bee and Cockroach: Comparable Organization in the Brain and Subesophageal Ganglion
TL;DR: In cockroaches and honey bees structurally comparable systems of perikarya and their extensive yet discrete systems of arborizations in neuropils are revealed and possible roles of octopamine in sensory integration and association are discussed.

Visual processing in the central bee brain

TL;DR: Data suggest that neurons along the visual pathway to the central brain not only are segregated with regard to the physical features of the stimuli, but also differ in the way they encode stimuli, possibly to allow for efficient parallel processing to occur.

TL;DR: The honeybee standard brain (HSB) serves as an interactive tool for relating morphologies of bee brain neurons and provides a reference system for functional and bibliographical properties and the most critical issue of this protocol in terms of user interaction time is drastically improved by the use of a model-based segmentation process.

Age-related plasticity in the synaptic ultrastructure of neurons in the mushroom body calyx of the adult honeybee Apis mellifera
TL;DR: Adult structural plasticity of input synapses in the microglomeruli of the olfactory lip and visual collar is investigated, suggesting that synaptic changes in calycal microcircuits of the mushroom body during periods of altered sensory activity and experience promote behavioral plasticity underlying polyethism and social organization in honeybees.

Age-dependent and task-related volume changes in the mushroom bodies of visually guided desert ants, Cataglyphis bicolor.
TL;DR: It is shown that even during this short period of adult life, Cataglyphis exhibits a remarkable increase in the size of its mushroom bodies, especially of the visual input region, the collar, if compared to age-matched dark-reared animals.

The dance language and orientation of bees
TL;DR: The Dance Language and Orientation of Bees as discussed by the authors is a seminal work in the field of honeybee behavior that describes in non-technical language what he discovered in a lifetime of study about honeybees - their methods of orientation, their sensory faculties, and their remarkable ability to communicate with one another.

Associative odor learning in Drosophila abolished by chemical ablation of mushroom bodies
JS de Belle,Martin Heisenberg +1 more
TL;DR: The results demonstrate that MBs mediate associative odor learning in flies, and that adult flies developing without MBs are unable to perform in a classical conditioning paradigm that tests associative learning of odor cues and electric shock.
