Chemicals selectively stimulating the olfactory nerve typically cannot be localized in a lateralization task. Purpose of this study was to investigate whether the ability of subjects to localize an olfactory stimulus delivered passively to 1 of the 2 nostrils would improve under training. Fifty-two young, normosmic women divided in 2 groups participated. One group performed olfactory lateraliza...

Bilateral cochlear implant (BiCI) users have shown variability in interaural time difference (ITD) sensitivity at different places along the cochlea. This paper investigates perception of multi-electrode binaural stimulation to determine if auditory object formation (AOF) and lateralization are affected by variability in ITD sensitivity when a complex sound is encoded with multi-channel process...

This paper presents a dichotic listening experiment on the perception of Mandarin tones under clean and noisy conditions. We examine the enhancing role of noise on the lateralization patterns of tones. We discover that the lateralization patterns of different tones are inconsistent: the perception of tone 1 exhibits a left ear advantage, while that of tone 2 or tone 4 has a right ear advantage....

It has been hypothesized that cerebral lateralization can significantly enhance cognition and that this was one of the primary selective forces shaping its wide-spread evolution amongst vertebrate taxa. Here, we tested this hypothesis by examining the link between cerebral lateralization and numerical discrimination. Guppies, Poecilia reticulata, were sorted into left, right and non-lateralized...

Functional MRI is a well-established tool used for pre-surgical planning to help the neurosurgeon have roadmap of critical functional areas that should be avoided, if possible, during surgery minimize morbidity patients with brain tumors (though this also has applications surgical resection epileptogenic tissue and vascular lesions). This article reviews locations secondary language centers wit...

This study tests how peripheral auditory processing and spectral dominance impact lateralization of precedence effect (PE) stimuli consisting of a pair of leading and lagging clicks. Predictions from a model whose parameters were set from established physiological results were tested with specific behavioral experiments. To generate predictions, an auditory nerve model drove a binaural, cross c...

Spatial relations within and between objects can be represented either coordinately or categorically. Coordinate representations concern metric and precise relations, and are strongly associated with right parietal cortex activity, while categorical representations relate to more qualitative, abstract relations, and have shown to have a, somewhat weaker, relationship with left parietal cortex a...

PURPOSE Our purpose was to determine the utility of functional MR imaging in conjunction with a word-generation paradigm in the assessment of language lateralization. METHODS Functional MR imaging and Wada testing for language lateralization was performed in patients with complex partial seizures during the performance of word-generation tasks. A language lateralization quotient was calculate...

OBJECTIVES/HYPOTHESIS One of the primary goals of endoscopic sinus surgery (ESS) is to create widely patent paranasal sinus ostia, but lateralization of the middle turbinate (MT) after ESS can obstruct otherwise patent ethmoid and maxillary sinuses. The aim of this study was to evaluate the effectiveness of turbinate-septal suturing in preventing lateralization of the MT. STUDY DESIGN A prosp...
