Odorant receptor specificities and receptor combinatorials: implications for olfactory coding.

The perception and discrimination of thousands of different odorants by the vertebrate olfactory system results from the activation of specific olfactory neurons within the olfactory epithelium of the nose (reviewed in Buck, 2000; Firestein, 2001). Activity from these cells is then interpreted by the brain to discern the molecular identity of a given odorant stimulus. How is this process of mol...

Environmental adaptation of olfactory receptor distributions

Olfactory receptor usage is highly non-uniform, with some receptor types being orders of magnitude more abundant than others. Intriguingly, in mammals the receptors are replaced regularly and the receptor distribution changes in response to olfactory experience. We propose a theoretical model that explains these experimental observations. Our model suggests that the receptor distribution is tun...

Efficient Olfactory Coding in the Pheromone Receptor Neuron of a Moth

The concept of coding efficiency holds that sensory neurons are adapted, through both evolutionary and developmental processes, to the statistical characteristics of their natural stimulus. Encouraged by the successful invocation of this principle to predict how neurons encode natural auditory and visual stimuli, we attempted its application to olfactory neurons. The pheromone receptor neuron o...

Olfactory coding in Drosophila larvae investigated by cross-adaptation.

In order to reveal aspects of olfactory coding, the effects of sensory adaptation on the olfactory responses of first-instar Drosophila melanogaster larvae were tested. Larvae were pre-stimulated with a homologous series of acetic esters (C3-C9), and their responses to each of these odours were then measured. The overall patterns suggested that methyl acetate has no specific pathway but was det...

A Scalable Coding Framework for Efficient Video Adaptation

Current digital video applications require video coding techniques that cater a wide range of quality levels, spatial resolutions and frame rates supporting different user preferences, varying transmission bandwidths and terminal capabilities. Efficient adaptation of video content is vital in such application environments. Encoding video in scalable formats support fast and efficient adaptation...
