Morphology of feedback neurons in the mushroom body of the honeybee, Apis mellifera.
The anatomy of gamma-aminobutyric acid (GABA)-immunoreactive, recurrent feedback neurons in the mushroom body (MB) of the honeybee, Apis mellifera, was investigated by using intraneuropilar injections of cobalt ions and light microscopic techniques. Each MB contains approximately 110 GABA-immunoreactive neurons, and approximately 50% of them are feedback neurons, i.e., they connect the MB outpu...
متن کاملMushroom body extrinsic neurons in the honeybee (Apis mellifera) brain integrate context and cue values upon attentional stimulus selection.
Multimodal GABA-immunoreactive feedback neurons in the honeybee brain connecting the output region of the mushroom body with its input are expected to tune the input to the mushroom body in an experience-dependent way. These neurons are known to change their rate responses to learned olfactory stimuli. In this work we ask whether these neurons also transmit learned attentional effects during mu...
متن کاملAssociative and Non-Associative Plasticity in Kenyon Cells of the Honeybee Mushroom Body
The insect mushroom bodies are higher-order brain centers and critical for odor learning. We investigated experience dependent plasticity of their intrinsic neurons, the Kenyon cells (KCs). Using calcium imaging, we recorded KC responses and investigated non-associative plasticity by applying repeated odor stimuli. Associative plasticity was examined by performing appetitive odor learning exper...
متن کاملLong-term memory and response generalization in mushroom body extrinsic neurons in the honeybee Apis mellifera.
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 - which belong to a recurrent tract connecting the output of the mushroom body with its input, potentially providing inhibitory feedback - and...
متن کاملOlfactory learning without the mushroom bodies: Spiking neural network models of the honeybee lateral antennal lobe tract reveal its capacities in odour memory tasks of varied complexities
The honeybee olfactory system is a well-established model for understanding functional mechanisms of learning and memory. Olfactory stimuli are first processed in the antennal lobe, and then transferred to the mushroom body and lateral horn through dual pathways termed medial and lateral antennal lobe tracts (m-ALT and l-ALT). Recent studies reported that honeybees can perform elemental learnin...
