Much progress has been made recently in understanding how olfactory coding works in
insect brains. Here, I propose a wiring diagram for the major steps from the first processing …

Dopamine (DA) is a central monoamine neurotransmitter involved in many physiological
and pathological processes. A longstanding yet largely unmet goal is to measure DA …

Using odors to find food and mates is one of the most ancient and highly conserved
behaviors. Arthropods from flies to moths to crabs use broadly similar strategies to navigate …

The neurotransmitter acetylcholine (ACh) regulates a diverse array of physiological
processes throughout the body. Despite its importance, cholinergic transmission in the …

How, why, and when consciousness evolved remain hotly debated topics. Addressing these
issues requires considering the distribution of consciousness across the animal …

Nervous systems contain sensory neurons, local neurons, projection neurons, and motor
neurons. To understand how these building blocks form whole circuits, we must distil these …

The hemibrain connectome provides large-scale connectivity and morphology information
for the majority of the central brain of Drosophila melanogaster. Using this data set, we …

During olfactory learning in fruit flies, dopaminergic neurons assign value to odor
representations in the mushroom body Kenyon cells. Here we identify a class of downstream …

The definition of neuronal type and how it relates to the transcriptome are open questions.
Drosophila olfactory projection neurons (PNs) are among the best-characterized neuronal …

The sense of smell enables animals to react to long-distance cues according to learned and
innate valences. Here, we have mapped with electron microscopy the complete wiring …
