Glutamatergic neurons are abundant in the Drosophila central nervous system, but their
physiological effects are largely unknown. In this study, we investigated the effects of …

Drosophila olfactory receptor neurons project to the antennal lobe, the insect analog of the
mammalian olfactory bulb. GABAergic synaptic inhibition is thought to play a critical role in …

In the Drosophila antennal lobe, excitation can spread between glomerular processing
channels. In this study, we investigated the mechanism of lateral excitation. Dual recordings …

Patterning of the antennal lobe of adult Drosophila occurs through a complex interaction
between sensory neurons, glia, and central neurons of larval and adult origin. Neurons from …

Odorant receptors in the periphery map precisely onto olfactory glomeruli (" coding
channels") in the brain. However, the odor tuning of a glomerulus is not strongly correlated …

Each odorant receptor gene defines a unique type of olfactory receptor neuron (ORN) and a
corresponding type of second-order neuron. Because each odor can activate multiple ORN …

We characterize an inhibitory circuit motif in the Drosophila olfactory system, parallel
inhibition, which differs from feedforward or feedback inhibition. Excitatory and GABAergic …

To understand how odor information is represented and processed in the antennal lobe (AL)
of Drosophila melanogaster, we have optically recorded glomerular calcium responses to …

Ionotropic glutamate receptors (iGluRs) mediate neuronal communication at synapses
throughout vertebrate and invertebrate nervous systems. We have characterized a family of …

Olfaction can elicit a rich perceptual experience. It is not known, however, whether olfactory
information is decomposed into various components and processed in distinct perceptual …
