Previous studies have demonstrated that cochlear implant (CI) patients are more efficient at performing sound categorisation than sound identification. However, it remains unclear how this categorisation capacity develops with time during the rehabilitation period after implantation. To investigate the role of the post-implantation auditory experie...

•Electric and infrared neural stimulation (INS) was applied to the cochlear nucleus.•Electric stimulation elicited collicular and auditory brainstem responses (ABRs).•INS also elicited colliculular responses & ABRs similar to acoustically-evoked ABRs.•Deafening decreased INS responses, suggesting their generation by a laser artifact.

•The ratio of the oVEMP amplitude to 500 and 1000 Hz may be diagnostically valuable in Menière's disease.•For Menière's ears, this ratio is significantly smaller compared to contralateral Menière's ears and healthy controls.•There is an association of an older age and a diminished amplitude ratio in healthy controls but not in Menière's ears.

•Residual inhibition (RI) was measured using bone-conducted ultrasound (BCU).•RI was induced by 30-kHz BCU in 90.5% of subjects (n = 19/21).•RI duration induced by BCU was significantly longer than those by 4-kHz sounds.•RI duration induced by BCU was not significantly different from that by white noise.

The study assessed the ability of the central nervous system (CNS) to use echoic information from sensory substitution devices (SSDs) to rotate the shoulders and safely pass through apertures of different width. Ten visually normal participants performed this task with full vision, or blindfolded using an SSD to obtain information regarding the wid...

Cognitive skills, such as processing speed, memory functioning, and the ability to divide attention, are known to diminish with aging. The present study shows that, despite these changes, older adults can successfully compensate for degradations in speech perception. Critically, the older participants of this study were not pre-selected for high pe...
