The basic psychophysical principle of speed-accuracy tradeoff (SAT) has been used to understand key aspects of neuronal information processing in vision and audition, but the principle of SAT is still debated in olfaction. In this study we present the direct observation of SAT in olfaction. We developed a behavioral paradigm for mice in which both the duration of odorant sampling and the diffic...

Intrasexual competition is an important element of natural selection in which the most attractive conspecific has a considerable reproductive advantage over the others. The conspecifics that are approached first often become the preferred mate partners, and could thus from a biological perspective have a reproductive advantage. This underlines the importance of the initial approach and raises t...

Introduction: Olfactory loss in patients with chronic rhinosinusitis has been measured by different methods. However, the results have been variable, and it is not clear whether endoscopic sinus surgery significantly improves olfactory function. This study was performed to evaluate the influence of endoscopic sinus surgery on olfactory function in patients with chronic rhinosinusitis.  Material...

Mammals rely on vision, audition, and olfaction to remotely sense stimuli in their environment. Determining how the mammalian brain uses this sensory information to recognize objects has been one of the major goals of psychology and neuroscience. Likewise, researchers in computer vision, machine audition, and machine olfaction have endeavored to discover good algorithms for stimulus classificat...

Cross-modal interactions between vision, audition and touch have been extensively studied in the last decade. However, our understanding of how the chemical senses interact with other sensory modalities remains relatively scarce. We performed a cued auditory localization paradigm in healthy young adults by measuring reaction times to monaural auditory stimuli after subjects had been cued by uni...

The sense of olfaction reached its zenith in development much earlier than other special senses. Olfaction is much more acute than the other senses, exhibits both high sensitivity for odours and high discrimination between them. This plays a very important role even in the social and behavioral aspects of human beings. Recent studies using molecular genetics, electrophysiology and behavioral an...

Some visual attributes, such as colour, are purely visual, but others, such as orientation and movement, can be perceived by touch or audition. A magnetic stimulation study has now shown that the perception of tactile orientation may be influenced by visual Information.
