The present study was carried out in the department of otorhinolaryngology at a Secondary health care institute, with aim screening new born (especially high risk) for hearing OAE (Oto Acoustic Emission test). Loss impairment auditory sense is most prevalent deficit all sensory organs. Hearing causes huge impact on one’s social, educational, and economic wellbeing. There are about 5 - 6 infants...

In addition to reducing carbon dioxide (CO 2 ) emissions, actively removing CO from the atmosphere is widely considered necessary keep global warming well below 2°C. Ocean Alkalinity Enhancement (OAE) describes a suite of such removal processes that all involve enhancing buffering capacity seawater. theory, OAE both stores and offsets ocean acidification. practice, response marine biogeochemica...

Auditory neuropathy is defined by the presence of normal evoked otoacoustic emissions (OAE) and absent or abnormal auditory brainstem responses (ABR). The sites of lesion could be at the cochlear inner hair cells, spiral ganglion cells of the cochlea, synapse between the inner hair cells and auditory nerve, or the auditory nerve itself. Genetic, infectious or neonatal/perinatal insults are the ...

Delay times in the mammalian cochlea, whether from measurement of basilar membrane (BM) vibration or otoacoustic emissions (OAEs) have, to date, been largely based on phase-gradient estimates from steady-state responses. Here we report cochlear delays measured directly in the time domain from OAEs evoked by amplitude-modulated tone-burst (AMTB) stimuli. Measurement using OAEs provides a non-inv...

In the present study, we have investigated the effects and interaction of CCK and GABAergic systems in the dorsal hippocampus of rats using the elevated plus-maze test of anxiety. Bilateral injection of different doses of CCK(8s) (0.01, 0.05 and 0.1 microg/rat) into the dorsal hippocampus (intra-CA1) decreased percentage of open arm time (%OAT) and open arm entries (%OAE) that are representativ...

The 2f1-f2 distortion product otoacoustic emission (DPOAE) is thought to arise primarily from the complex interaction of components that come from two different cochlear locations. Such distortion has its origin in the nonlinear interaction on the basilar membrane of the excitation patterns resulting from the two stimulus tones, f1 and f2. Here we examine the spatial extent of initial generatio...
