1. The electrocochleograpy in the auditory neuropathy/auditory dyssynchrony / "A eletrococleografia na neuropatia/dessincronia auditiva"
The auditory neuropathy/auditory dys-synchrony is characterized by the normal cochlear functioning due to the presence of the otoacoustic emissions and/or of the cochlear microphonic associated to the absence of the auditory brainstem response. This study had as an objective to evaluate the cochlear and neural functions in individuals with the diagnosis of a

2. Low-frequency characteristics of intracellularly recorded receptor potentials in guinea-pig cochlear hair cells.
Intracellular receptor potentials were recorded from inner and outer hair cells in response to low-frequency tones, from the basal, high-frequency region of the guinea-pig cochlea. The receptor potentials recorded from inner hair cells are asymmetrical about the resting membrane potential with the depolarizing phase, which corresponds to rarefaction in sound

3. Abnormal Cochlear Potentials from Deaf Patients with Mutations in the Otoferlin Gene
Otoferlin is involved in neurotransmitter release at the synapse between inner hair cells (IHCs) and auditory nerve fibres, and mutations in the OTOF gene result in severe to profound hearing loss. Abnormal sound-evoked cochlear potentials were recorded with transtympanic electrocochleography from four children with otoferlin (OTOF) mutations to evaluate phy

4. Receptor potentials of lizard hair cells with free-standing stereocilia: responses to acoustic clicks.
Receptor potentials of single hair cells in the free-standing region of the basilar papilla of the anaesthetized alligator lizard were measured intracellularly with micropipettes. Stimuli were primarily acoustic pulses (clicks) delivered to the tympanic membrane. The receptor potential was independent of click repetition rate for the range 10-150 clicks/s. T
