Twentv riaht-handed Ss listened to a dichotic tape in which one of six consonant-vowel syllables was paired with a burst of white noise on each trial. Eight blocks of 40 trials were presented. with the syllables within a block presented to the same ear. On each trial. Ss decided if /ba/ was presented. Mean RT to right-ear items was 440.0 msec. while mean left-ear RT was 453.6 msec. Responses in...

We report five cases of duplicated external ear canal with especial attention to its histology and surgical care of facial nerve for their complete resection. These five patients were selected from 50 cases of first bronchial cleft anomalies including atretic external ear canals, preauricular fistula, cyst and sinuses. The characteristic histopathology and clinical features such as external ope...

Serios otitis media is one of those ear Trou­bles that has enjoyed a very extensive research two decaides.  I ts recognition in medical literature goes b,ick tc eighteenth century. Since then there has been rather little progress in this field. The dis­covery of antibiotcs and thence lessening of in­ fecticus ear diseases, attention has been paid to preserve the function of ear, and naturally...

OBJECTIVES/HYPOTHESIS Ventilation of the chronically inflamed middle ear is a key outcome in functional middle ear surgery. Grommets eliminate middle ear effusion, but there is also evidence that they downregulate inflammation. The reason for this is not understood, but there is little to suggest alteration in eustachian tube ventilatory capacity. Previous work has shown that the Junbo mouse mo...

In most of the surviving patients after a lightning strike, audiovestibular abnormalities have been reported. The most frequently reported type of abnormalities is a tympanic membrane perforation with hearing loss and external ear canal burn. However a sensor neural hearing loss and mixed type hearing loss can also occur, but these occur rarely. A nineteen-year-old female patient had, after a l...

An experiment was conducted at Institute of Agriculture and Animal Science (IAAS), Rampur, Nepal during July 2011 to September 2011 with an objectine to determine phenotypic variability of Nepalese finger millet landraces using descriptive statistics, cluster analysis and principal component analysis. FValue of REML procedure of mixed model analysis revealed that highly significant variation wa...

Background: Hearing loss is one of the common complaints of diabetics. The aim of this study was to evaluate the hearing status of diabetic patients in Babol, North of Iran. Methods: The hearing status of 50 type 2 diabetic patients (case group) and 50 healthy individuals (control group) were evaluated from October 2011 to September 2012. Audiometry was done with the frequencies of 250, 500, 1...

Using adequate sample size in experimental units improves the efficiency of the research. In the agricultural year of 2004/2005, an experiment was conducted in Santa Maria, Rio Grande do Sul State, Brazil, with the objective of estimating sample size for the following traits: ear length, ear and cob diameter, ear weight, weight of grains per ear, cob weight and the weight of 100 grains, number ...

Cherry (1953) reported that when listeners were presented with dichotic signal over headphones, they could reliably report words presented to the attended ear, while only being aware of the gross properties of the talker in the unattended ear. More recently, Gallun et al. (2007) showed that there were large differences in performance on dichotic tasks depending on ear of presentation, with sign...
