Attention selects behaviorally relevant stimuli for greater neural representation. In this issue of Neuron, Luo and Maunsell (2015) show that attention acts, in part, by boosting the signal-to-noise ratio (SNR) of sensory neurons.

Background: Recently, it has been shown that increasing body mass index (BMI) in asthma is associated with reduced exhaled NO. Our objective in this study was to determine if the BMIrelated changes in exhaled NO differ across asthmatics and controls, and to determine if these changes are related to increased airway oxidative stress and systemic levels of leptin and adiponectin. Methods: Observa...

Variability in speaking rate results in a many-to-many mapping between acoustic properties in speech and the linguistic interpretation of an utterance. In order to recognize the phonetic structure of an utterance, listeners must calibrate their phonetic decisions against the rate at which the speech was produced. This process of rate normalization is fast and effective allowing listeners to mai...
