Subdivisions of hymenopteran mushroom body calyces by their afferent supply

  • 9 July 2001
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.
Morphologic representation of visual and antennal information in the ant brain
Data is presented supporting the view that the mushroom bodies may participate in spatial orientation, landmark recognition, and visual information storage, and the size and manifestation of the eyes generally correlates well with that of the optic lobes.
Fast actions in small animals: springs and click mechanisms

In flight, sound generation, jumping, or predatory strikes arthropods employ different strategies to transform muscular action to the desired movement, while other accessory structures such as snap mechanism or latches with trigger mucles determined the stability and the timing of the instantaneous discharge in catapult mechanisms.
Molecular traces of alternative social organization in a termite genome.
The genome and stage-specific transcriptomes of the dampwood termite Zootermopsis nevadensis (Blattodea) are sequence and similarities in the number and expression of genes related to caste determination mechanisms support a hypothesized epigenetic regulation of caste differentiation.
Segregation of visual input to the mushroom bodies in the honeybee (Apis mellifera)
This work describes visual inputs to the calyces of the mushroom bodies of the honeybee Apis mellifera, the neurons' dendritic fields in the optic lobes, the medulla and lobula, and the organization of their terminals in the calYces, indicating that the mushroom body may be composed of many more functional subsystems than previously suggested.
Draft genome of the red harvester ant Pogonomyrmex barbatus
Gene networks involved in generating key differences between the queen and worker castes show signatures of increased methylation and suggest that ants and bees may have independently co-opted the same gene regulatory mechanisms for reproductive division of labor.
Structure and function of ant (Hymenoptera: Formicidae) brains: Strength in numbers
The structure and function of major brain neuropils is described (visual and olfactory centers and central multi-sensory integrative brain compartments) together with some of their neurons.
Mushroom body volumes and visual interneurons in ants: Comparison between sexes and castes
The structure of visual neurons is described and the volume of brain structures involved in visual processing, especially the optic lobes and parts of the mushroom bodies receiving visual input in males, winged females, and workers of carpenter ants (Camponotus).
Descending neurons supplying the neck and flight motor of diptera: Physiological and anatomical characteristics
In Diptera, dorsal neuropils of the pro‐, meso‐, and metathoracic ganglia supply motor neurons to neck and flight muscles, suggesting that flight descending neurons should respond to complex stimuli reflecting panoramic movement and small‐field motion.
Oculomotor control in calliphorid flies: Organization of descending neurons to neck motor neurons responding to visual stimuli
Examining the relationships between neck muscle motor neurons and the terminals visiting them from approximately 50 pairs of descending neurons suggests a role for tactile, gustatory, and olfactory signals in controlling head position.
