OBJECTIVE For patients with relatively good low-frequency hearing and relatively poor high-frequency hearing, who met the pre-implant criteria for combined electric and acoustic stimulation (EAS), our aims were to i) assess deficits in low-frequency auditory function, ii) to identify measures which might be sensitive to changes resulting from the insertion of an intracochlear electrode array, a...

Response properties of neurons in the inferior colliculus (IC) were examined in control and profoundly deafened animals to electrical stimulation of the auditory nerve. Seven adult cats were used: two controls; four neonatally deafened (2 bilaterally, 2 unilaterally); and one long-term bilaterally deaf cat. All control cochleae were deafened immediately before recording to avoid electrophonic a...

When two objects are flashed at one location in close temporal proximity in the visual periphery, an intriguing illusion occurs whereby a single flash presented concurrently at another location appears to flash twice (the visual double-flash illusion: Chatterjee et al., 2011, Wilson & Singer, 1981). Here, for the first time, we investigate the time course of the effect, and directly compare it ...

Based on the empirical findings on the human cortical locations responsive to auditory and/or visual stimuli, the objective of this work is to study the neural interactions within and across these cortical locations using electrocorticography (ECoG) signals. To this end, we obtain the brain functional connectivity networks under three basic speech conditions, namely auditory-only, visual-only a...

Under normal conditions, human speech is remarkably robust to degradation by noise and other distortions. However, people with hearing loss, including those with cochlear implants, often experience great difficulty in understanding speech in noisy environments. Recent work with normal-hearing listeners has shown that the amplitude fluctuations inherent in noise contribute strongly to the maskin...

Malignant otitis externa is an inflammation of the external auditory canal with preceding osteomyelitis temporal bone and adjacent structures that could be potentially lethal. may present cranial nerve involvements massive spread disease mimicking nasopharyngeal carcinoma or any other malignancies on imaging. Two elderly patients who presented severe otalgia significant facial palsy lower palsi...

It has been reported that many elderly persons exhibit problems in identifying the location of fused auditory images in a test of the precedence effect in sound localization. The precedence effect involves the neural integration of multiple competing binaural temporal cues, and may reflect subtle age-related neural timing or integration problems. This study investigated whether elderly persons ...
