Structural and functional analysis of axonal-axonal reciprocal connections between dopamine neurons and Kenyon cells provides insight into the brain computations for normal associative olfactory learning.
Electrophysiological recordings and a large-scale biophysical model show that a unique inhibitory neuron plays a central role in structuring olfactory codes in the insect brain.
Muscarinic acetylcholine receptor type A in adult Drosophila inhibits Kenyon cells, and is required for aversive olfactory learning and learning-associated synaptic depression between Kenyon cells and their output neurons.
The generation and systematic characterisation of driver lines labelling a large number of neurons in the Drosophila innate olfactory processing centre bridges electron microscopy neuronal reconstructions, circuits and behaviour.
A recurrent reward circuit in Drosophila, comprised of specific dopamine neurons and a single class of mushroom body output neurons, transforms a nascent memory trace into a stable long-term memory.
Using Drosophila as a model organism shows that neural stem cell proliferation decisions in response to dietary nutrient conditions can be regulated by cell-autonomous lineage factors.
One memory center in the fly brain processes distinct appetitive and aversive associative memories of olfactory and visual cues using shared local circuits.
Drep-2 is the first representative of the evolutionary conserved CIDE-N protein family found at synapses and is required for associative learning by functionally intersecting with metabotropic signaling.
Alcohol modifies dopaminergic microcircuits required for acquisition and expression of sensory memories in Drosophila resulting in a shift in behavioral response from malleable to inflexible.
