painless, a Drosophila Gene Essential for Nociception
We describe a paradigm for nociception in Drosophila. In response to the touch of a probe heated above 38 degrees C, Drosophila larvae produce a stereotypical rolling behavior, unlike the response toExpand

Oscillations and Sparsening of Odor Representations in the Mushroom Body
In the insect olfactory system, oscillatory synchronization is functionally relevant and reflects the coherent activation of dynamic neural assemblies. We examined the role of such oscillatoryExpand

Computation of Object Approach by a Wide-Field, Motion-Sensitive Neuron
The lobula giant motion detector (LGMD) in the locust visual system is a wide-field, motion-sensitive neuron that responds vigorously to objects approaching the animal on a collision course. WeExpand

  • 1 November 2002
The brain faces many complex problems when dealing with odorant signals. Odours are multidimensional objects, which we usually experience as unitary percepts. They are also noisy and variable, but weExpand

Encoding of Olfactory Information with Oscillating Neural Assemblies
In the brain, fast oscillations of local field potentials, which are thought to arise from the coherent and rhythmic activity of large numbers of neurons, were observed first in the olfactory systemExpand

Dynamic optimization of odor representations by slow temporal patterning of mitral cell activity.
Mitral cells (MCs) in the olfactory bulb (OB) respond to odors with slow temporal firing patterns. The representation of each odor by activity patterns across the MC population thus changesExpand

Distinct Mechanisms for Synchronization and Temporal Patterning of Odor-Encoding Neural Assemblies
Stimulus-evoked oscillatory synchronization of neural assemblies and temporal patterns of neuronal activity have been observed in many sensory systems, such as the visual and auditory cortices ofExpand

Normalization for Sparse Encoding of Odors by a Wide-Field Interneuron
A single neuron is responsible for adaptive normalization in an olfactory circuit generating sparse odor representations. Sparse coding presents practical advantages for sensory representations andExpand

Elementary Computation of Object Approach by a Wide-Field Visual Neuron
An essential function of the brain is to detect threats, such as those posed by objects or predators on a collision course. A wide-field, movement-sensitive visual neuron in the brain of the locustExpand

Invariance of Angular Threshold Computation in a Wide-Field Looming-Sensitive Neuron
The lobula giant motion detector (LGMD) is a wide-field bilateral visual interneuron in North American locusts that acts as an angular threshold detector during the approach of a solid square along aExpand
