Abstract In a complex environment, animals learn from their responses to stimuli and events. Appropriate response to reward and punishment can promote survival, reproduction and increase evolutionary fitness. Interestingly, the neural processes underlying these responses are remarkably similar across phyla. In all species, dopamine is central to encoding reward and directing motivated behaviors, however, a comprehensive understanding of how circuits encode reward and direct motivated behaviors… 
Dopamine modulation of sensory processing and adaptive behavior in flies
TLDR
The fly is an attractive system to study the roles of dopamine in decision making and state-dependent behavior because a learning and memory center—the mushroom body—is richly innervated by dopaminergic neurons that enable it to integrate multi-modal information according to state and context, and to modulate decision-making and behavior.
A Fly’s Eye View of Natural and Drug Reward
TLDR
An overview of the research on natural and drug reward in D. melanogaster is provided, including natural rewards such as sugar and other food nutrients, and drug rewards including ethanol, cocaine, amphetamine, methamphetamine, and nicotine.
Drosophila reward system - A summary of current knowledge
Dissection of the Drosophila neuropeptide F circuit using a high-throughput two-choice assay
TLDR
A simple two-choice, high-throughput assay suitable for performing large neuronal activation screens for neural circuits involved in reward perception/processing in flies, and shows that optogenetic activation of NPF neuron is rewarding in olfactory conditioning experiments and that the preference forNPF neuron activation is dependent on NPF signaling.
Mechanisms Underlying the Risk to Develop Drug Addiction, Insights From Studies in Drosophila melanogaster
TLDR
This paper reviews studies in Drosophila melanogaster that model different aspects of natural and drug rewards, with an emphasis on how motivational states shape the value of the rewarding experience, as an entry point to understanding the mechanisms that contribute to the vulnerability of drug addiction.
Circuits that encode and guide alcohol-associated preference
TLDR
It is shown that circuits required for alcohol-associated preference shift from population level dopaminergic activation to select dopamine neurons that predict behavioral choice in Drosophila melanogaster.
Neurogenetics of connectomes: from fly to fish
The Journal of Neurogenetics presents this special issue entitled ‘‘Neurogenetics of connectomes: from fly to fish.’’ In this special issue, we invited established researchers to review and present
Circuits that encode and predict alcohol associated preference
TLDR
How circuits required for alcohol associated preference shift from population level dopaminergic activation to select dopamine neurons that predict behavioral choice is defined and insight into the inflexible, maladaptive nature of alcohol associated memories is provided.
Come Fly with Me: an overview of dopamine receptors in Drosophila melanogaster.
TLDR
An overview of the homology between human and Drosophila dopaminergic systems is provided and the current literature on the pharmacology, molecular signalling mechanisms, and behavioural outcomes of DA receptor activation in the Dosophila brain is reviewed.

Neural mechanisms of reward in insects.
TLDR
This work compares what is known of reward processing mechanisms in insects with the well-studied vertebrate reward systems, suggesting a modular structure to the insect reward processing system, which broadly parallels that of the mammals in terms of functional organization.
Toward elucidating diversity of neural mechanisms underlying insect learning
TLDR
There are unexpected diversities in basic mechanisms of learning and memory among different insect species, especially between crickets and fruit flies.
Neuropeptide F neurons modulate sugar reward during associative olfactory learning of Drosophila larvae.
TLDR
It is demonstrated that artificial activation of dNPF neurons inhibits appetitive olfactory learning by modulating the sugar reward signal during acquisition, and a new part of the sugar reinforcement signaling pathway for classical Olfactory conditioning in Drosophila larvae is described.

Layered reward signaling through octopamine and dopamine in Drosophila
TLDR
It is shown, using temporal control of neural function in Drosophila, that only short-term appetitive memory is reinforced by octopamine, andOctopamine-dependent memory formation requires signalling through dopamine neurons, and that reinforcement systems in flies are more similar to mammals than previously thought.
A subset of dopamine neurons signals reward for odour memory in Drosophila
TLDR
It is shown that a group of dopamine neurons in the protocerebral anterior medial (PAM) cluster signals sugar reward by transient activation and inactivation of target neurons in intact behaving flies and highlights the cellular specificity underlying the various roles of dopamine and the importance of spatially segregated local circuits within the MBs.

Input-specific control of reward and aversion in the ventral tegmental area
TLDR
It is established that distinct VTA circuits generate reward and aversion, and thereby provides a new framework for understanding the circuit basis of adaptive and pathological motivated behaviours.
