Evolving olfactory systems on the fly

The detection of odour stimuli in the environment is universally important for primal behaviours such as feeding, mating, kin interactions and escape responses. Given the ubiquity of many airborne chemical signals and the similar organisation of animal olf ...

Emergent Dynamics in Neocortical Microcircuits

Rodrigo de Campos Perin

Interactions among neurons can take place in a wide variety of forms. It is the goal of this thesis to investigate the properties and implications of a number of these interactions that we believe are relevant for information processing in the brain. Neuro ...

Dual activities of odorants on olfactory and nuclear hormone receptors

Horst Vogel, Horst Pick, Olivia Baud, Sylvain Etter, Ralf Schmauder

We have screened an odorant compound library and discovered molecules acting as chemical signals that specifically activate both G-protein-coupled olfactory receptors (ORs) on the cell surface of olfactory sensory neurons and the human nuclear estrogen rec ...

Large-scale production and study of a synthetic G protein-coupled receptor: Human olfactory receptor 17-4

Horst Vogel, Horst Pick

Although understanding of the olfactory system has progressed at the level of downstream receptor signaling and the wiring of olfactory neurons, the system remains poorly understood at the molecular level of the receptors and their interaction with and rec ...

Structure and function of the olfactory bulb microcircuit

Michele Pignatelli

The aim of this study is to contribute to understand the physiology of the Olfactory System through detailed microcircuit investigation, adopting advanced electrophysiological and anatomical techniques. Multiple patch clamp recordings allow understanding t ...

Alteration of brain glycogen turnover in the conscious rat after 5h of prolonged wakefulness

Rolf Gruetter, Pierre Magistretti, Bernard Lanz, Jean-Marie Petit, Hanne Frenkel

Although glycogen (Glyc) is the main carbohydrate storage component, the role of Glyc in the brain during prolonged wakefulness is not clear. The aim of this study was to determine brain Glyc concentration ([]) and turnover time (tau) in euglycemic conscio ...

Occurrence of dissolved and particle-bound taste and odor compounds in Swiss lake waters

Urs von Gunten

The occurrence of algal taste and odor (T&O) compounds was investigated in three Swiss lakes which exhibit different nutrient levels from eutrophic to oligotrophic (Lake Greifensee, Lake Zurich and Lake Lucerne). Apart from dissolved T&O compounds, the stu ...

Interleaving bisection stimuli - randomly or in sequence - does not disrupt perceptual learning, it just makes it more difficult

Michael Herzog, Carl Kristoffer Aberg

Presenting stimuli of two or more stimulus types randomly interleaved, so called roving, disrupts perceptual learning in many paradigms. Recently, it was shown that no disruption occurs when Gabor stimuli were presented interleaved in sequence, instead of ...

Nanobiosensors based on individual olfactory receptors

Luis Guillermo Villanueva Torrijo

The animal olfactory system represents the gold standard of biosensors, due to its ability to identify and discriminate thousands of odorant compounds with very low thresholds. Using olfactory receptors (ORs) as sensing elements instead of chemical sensors ...

Modified Trans-synaptic Tracing Viruses Reveal Novel Connectivity in the Rat Olfactory Bulb

Aurélie Pala

Olfaction and the olfactory pathway is a good system to study sensory processing in general, mainly because of the simplified organization of the cells constituting the olfactory bulb, the anatomical structure responsible for early odor encoding and proces ...
