Distinct associative learning abilities for colour and odour in the flower-feeding Drosophila elegans and the fruit-feeding Drosophila melanogaster

This study compares odour and colour associative learning in two Drosophila species, finding D. elegans has better colour learning but worse odour learning than D. melanogaster.

Ferulic acid eicosyl ester enhances cognitive flexibility and modulates arousal-related neural circuits in mice

This study shows that FAE-20 improves cognitive flexibility in young adult mice but not spatial learning, with sex-specific effects on arousal-related neural circuits.

Starvation modulates associative short-term memory of Drosophila in a task-dependent manner

This study examines how starvation affects associative short-term memory in Drosophila across various learning tasks, finding task-dependent effects that challenge the adaptive specificity hypothesis.

Avoidance engages dopaminergic punishment in Drosophila

The paper shows that inducing backward movement in Drosophila engages dopaminergic punishment and supports aversive memories, explaining the avoidance paradox.

Compromising tyrosine hydroxylase function establishes a delusion-like temporal profile of reinforcement by dopamine neurons in Drosophila

This study shows that impairing tyrosine hydroxylase in Drosophila alters dopamine neuron reinforcement timing, mimicking delusional causality attribution in different conditioning paradigms.

Prediction error drives associative olfactory learning and conditioned behavior in a spiking model of Drosophila larva

The paper develops a spiking neural network model of Drosophila larva olfactory learning that uses prediction error to drive associative learning and behavior.

Rewarding capacity of optogenetically activating a giant GABAergic central-brain interneuron in larval Drosophila

The paper investigates the role of the APL neuron in larval Drosophila, finding that optogenetic activation can induce a rewarding effect through dopaminergic pathways.

High-resolution analysis of individual Drosophila melanogaster larvae within groups uncovers inter- and intra-individual variability in locomotion and its neurogenetic modulation

The paper introduces IMBA, a tool for analyzing individual Drosophila larva behavior, revealing inter- and intra-individual locomotion variability and its genetic modulation.

Optogenetically induced reward and 'frustration' memory in larval Drosophila

The paper characterizes reward and frustration memory in larval Drosophila using optogenetics and behavioral assays, revealing timing-dependent memory valence based on reward occurrence or termination.

A quick and versatile protocol for the 3D visualization of transgene expression across the whole body of larval Drosophila

This paper describes a protocol for whole-body multifluorescence imaging of larval Drosophila using optimized clearing and imaging techniques.

Multilevel feedback architecture for adaptive regulation of learning in the insect brain

The paper maps the synaptic connectome of the Drosophila larva mushroom body and identifies feedback pathways that enable modulatory neurons to compute teaching signals for reinforcement learning.

The Complete Connectome Of A Learning And Memory Center In An Insect Brain

The paper reconstructs the complete synaptic connectome of the Drosophila larval mushroom body, revealing novel circuit structures and input integration patterns in Kenyon cells.
