... of Biologists Ltd 2019 http://www.biologists.com/user-licence-1-1/ Summary: An associative conditioning paradigm shows that there is an absence of evidence for lateral transfer of olfactory memory in the bees Apis mellifera and Apis dorsata . PER conditioning Mushroom body Olfactory...

...Melanie Haehnel; Randolf Menzel SUMMARY Honeybees learn to associate an odor with sucrose reward under conditions that allow the monitoring of neural activity by imaging Ca 2+ transients in morphologically identified neurons. Here we report such recordings from mushroom body extrinsic neurons...

...Anna Balkenius; Sonja Bisch-Knaden; Bill Hansson SUMMARY The responses to bimodal stimuli consisting of odour and colour were recorded using calcium-sensitive optical imaging in the mushroom bodies of the hawkmoth Manduca sexta . The results show that the activity in the mushroom bodies...

... projection neurons and mushroom body Kenyon cells in the brain of the honeybee Apis mellifera . Rhodamine-labelled neurons were identified in vitro prior to recording, and whole-cell K + and Ca 2+ currents were measured. All neurons expressed transient and sustained outward K + currents, but Kenyon cells...

... in the fruitfly, in the novel context of the neurobiology of aggression. We find that octopamine, dopamine and a region in the Drosophila brain called the mushroom bodies, all profoundly influence the expression of aggressive behaviour. Serotonin had no effect. We conclude that Drosophila , with its advanced set...
