Noise‐induced increased responsiveness in the acoustic reflex mechanism

The time course of the acoustic reflex.

The time course of the impedance changes caused by the contralateral acoustic reflex was investigated in five normal hearing, young adult subjects The acoustic reflex function was measured with equipment having a time constant of 15 milliseconds which permitted precise temporal measures. Temporal intervals from signal onset and termination to various portions of the acoustic reflex function wer...

Cerebellar interaction with the acoustic reflex.

The involvement of the cerebellar vermis in the acoustic reflex was analyzed in 12 cats, decerebrated or in pentobarbital anesthesia. Anatomical data suggested the existence of a connection of lobules VIII with the ventral cochlear nucleus. Single cell recording and evoked potential techniques demonstrated the existence of the acoustic projection to lobulus VIII. Electrical stimulation of this ...

Increased visceral pain responsiveness in female mice compared to male mice afer partial sciatic nerve ligation

Neuropathic pain which is a chronic pain causes hyperalgesia due to peripheralm nerve damage.the relation between neuropathic pain and hyperalgesia and the response to treatment in case of somatic and inflammatory pain have been investigated previuosly.however the response of visceral pain in peripheral neuropathy and the possible gender differences in visceral pain response and gender differnc...

Characterization of Acoustic Reflex Latency in Females

Acoustic Reflex Latency (ARL) is the time interval between onset of an intense auditory stimulus and onset of middle-ear muscle contraction. Unlike pure tone audiogram, the usual procedure to detect middle ear disorders and conductive hearing loss, ARL can differentiate between cochlear and retrocochlear pathologies, yields information about the nature of the conductive disorder, can detect mil...
