The Drosophila brain contains a relatively simple circuit for forming Pavlovian associations,
yet it achieves many operations common across memory systems. Recent advances have …

Making inferences about the computations performed by neuronal circuits from synapse-
level connectivity maps is an emerging opportunity in neuroscience. The mushroom body …

Understanding memory formation, storage and retrieval requires knowledge of the
underlying neuronal circuits. In Drosophila, the mushroom body (MB) is the major site of …

Animals discriminate stimuli, learn their predictive value and use this knowledge to modify
their behavior. In Drosophila, the mushroom body (MB) plays a key role in these processes …

Learned and adaptive behaviors rely on neural circuits that flexibly couple the same sensory
input to alternative output pathways. Here, we show that the Drosophila mushroom body …

Dopamine plays a central role in motivating and modifying behavior, serving to invigorate
current behavioral performance and guide future actions through learning. Here we examine …

To understand the brain, molecular details need to be overlaid onto neural wiring diagrams
so that synaptic mode, neuromodulation and critical signaling operations can be considered …

Although associative learning has been localized to specific brain areas in many animals,
identifying the underlying synaptic processes in vivo has been difficult. Here, we provide the …

Animals rely on the relative timing of events in their environment to form and update
predictive associations, but the molecular and circuit mechanisms for this temporal …
