Rodents can localize odor sources by comparing odor inputs to the right and left nostrils. However, the neuronal circuits underlying such odor localization are not known. We recorded neurons in the anterior olfactory nucleus (AON) while administering odors to the ipsilateral or contralateral (ipsi- or contra-) nostril. Neurons in the AON pars externa (AONpE) showed respiration phase-locked exci...

A 69 year-old man, with bilateral inflamed sinonasal polyps that had been treated medically for years, referred for surgical treatment suffering from moderate progressive bilateral nasal obstruction, sinus pressure with no rhinorrhoea or other symptoms and typical bilateral inflamed polyps emerging from the middle meatus, not exceeding the level of the lower concha (Endoscopic Appearance Score ...

This work is motivated by the goal of providing a non-contact means of controlling the mouse pointer on a computer system for people with motor difficulties using low-cost, widely available hardware. The required information is derived from video data captured using a web camera mounted below the computer’s monitor. A colour filter is used to identify skin coloured regions. False positives are ...

introduction: neonatal nasal airway obstruction induces various degrees of respiratory distress. the management of this disease, including surgical repair, will depend on the severity and location of the obstruction. we describe here a case of congenital nasal nostril stenosis that required surgical repair for stenting of both nares after coanal atresia repair.   case report: a 2 days old femal...

Breathing waveform extracted via nasal thermistor is the most common method to study respiratory function in sleep studies. In essence, this is a temporal waveform of mean temperatures in the nostril region that at every time step collapses two-dimensional data into a single point. Hence, spatial heat distribution in the nostrils is lost along with valuable functional and anatomical cues. This ...

When two different images are presented to the two eyes, we perceive alternations between seeing one image and seeing the other. Termed binocular rivalry, this visual phenomenon has been known for over a century and has been systematically studied in recent years at both the behavioral and neural levels. A similar phenomenon has been documented in audition. Here we report the discovery of alter...
