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 …

Neural coding for olfactory sensory stimuli has been mapped near completion in the
Drosophila first-order center, but little is known in the higher brain centers. Here, we report …

In most sensory modalities, neuronal connectivity reflects behaviorally relevant stimulus
features, such as spatial location, orientation, and sound frequency. By contrast, the …

Local interneurons are essential in information processing by neural circuits. Here we
present a comprehensive genetic, anatomical and electrophysiological analysis of local …

The larval brain of Drosophila is a useful model to study olfactory processing because of its
cellular simplicity. The early stages of central olfactory processing involve the detection of …

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 …

Neural circuits are often remodeled after initial connections are established. The
mechanisms by which remodeling occurs, in particular whether and how synaptically …

In the first brain relay of the olfactory system, odors are encoded by combinations of
glomeruli, but it is not known how glomerular signals are ultimately integrated. In Drosophila …

Chemotopic odour representations in the olfactory bulb are transferred to multiple forebrain
areas and translated into appropriate output responses. However, a comprehensive …

Odor representations are initially formed in the olfactory bulb, which contains a topographic
glomerular map of odor molecular features. The bulb transmits sensory information directly …
