Auditory disturbances in patients with complex regional pain syndrome

Pain, 2022
Abstract Complex regional pain syndrome (CRPS) is often associated with reduced sound tolerance (hyperacusis) on the affected side, but the mechanism of this symptom is unclear. As compensatory increases in central auditory activity after cochlear injury may trigger hyperacusis, hearing and discomfort thresholds to pure tones (250, 500, 1000,

The use of broad vs restricted regions of interest in functional near-infrared spectroscopy for measuring cortical activation to auditory-only and visual-only speech.

Hearing Research, 2021
As an alternative to fMRI, functional near-infrared spectroscopy (fNIRS) is a relatively new tool for observing cortical activation. However, spatial resolution is reduced compared to fMRI and often the exact locations of fNIRS optodes and specific ...

A cortical region sensitive to auditory spectral motion

NeuroReport, 2000
The functional architecture of human auditory cortex is still poorly understood compared with that of visual cortex, yet anatomical and electrophysiological studies in non-human primates suggest that the auditory cortex also might be functionally specialized, in a model of parallel and hierarchical organization.

Regional Cerebral Blood Flow Correlates of Auditory Processing

Archives of Neurology, 1982
To study the regional cerebral blood flow (rCBF) correlates of auditory processing, we performed rCBF measurements in young, normal right-handed volunteers engaged in listening tasks. Using the xenon Xe 133 inhalation technique, rCBF was measured in 11 regions in each hemisphere.

Auditory P300 in Young Alcoholics: Regional Response Characteristics

Alcoholism: Clinical and Experimental Research, 1995
An auditory oddball paradigm was used to record the P300 component of the event‐related potential (ERP) in a group of medication‐free, chronic male alcoholics (n= 51, mean = 32.2) and a control group (n= 25, mean = 27.2). Each subject received a binaurally presented series of high (1600‐Hz)‐ and low (600‐Hz)‐frequency tones. The designation of the rare

An auditory-like region in the motor cortex

The Journal of the Acoustical Society of America, 2021
Left premotor cortex is activated during listening to speech, but whether this reflects a motor mechanism or a response to auditory features is debated. Previously, we showed that left dorsal premotor cortex (dPM) responded to vocal pitch in a degraded speech recognition task, but only when speech was rated as unintelligible. Crucially, vocal pitch was

Auditory stimuli activate parietal brain regions

NeuroReport, 1994
Previous studies using magnetoencephalographic (MEG) recordings have revealed neuronal populations responding to discrete auditory stimuli in the supratemporal cortex of the human brain. We used the novel whole-head magnetometer (Neuromag-122) to determine whether regions outside the auditory cortex are activated by auditory stimulation as well. In the

Regional Brain Metabolism During Auditory Hallucinations in Chronic Schizophrenia

British Journal of Psychiatry, 1990
Regions of the brain involved in language and attention were studied using [18F]-fluorodeoxyglucose in PET. In nine chronic DSM–III schizophrenic patients who had persistent auditory hallucinations, ten who had recovered from hallucinations and ten normal controls.

Some neurochemical studies on auditory regions of mouse brain

Experimental Brain Research, 1979
The mouse brain auditory pathway has been dissected into five regions: geniculate bodies, posterior colliculi, superior olives, cochlear nuclei, and cochleas. The following analyses were made in these regions and in the auditory cortex: protein, glutamate, gamma-aminobutyrate, taurine, choline acetyltransferase, and glutamate decarboxylase.

Regional distribution of neurotrophin receptors in the developing auditory brainstem

The Journal of Comparative Neurology, 1996
Neuron survival and axonal regeneration become severely limited during early postnatal development. In conjunction with our recent organotypic analysis of regeneration in the auditory midbrain, we wished to determine whether neurotrophins could serve as a trophic substance during the postnatal period.
