The Relationship between Contralateral Suppression of Transient Evoked Otoacoustic Emission and Unmasking of Speech Evoked Auditory Brainstem Response

open access: yesInternational Archives of Otorhinolaryngology, 2022
Introduction Several studies have shown that efferent pathways of the auditory system improve perception of speech-in-noise. But, the majority of investigations assessing the role of efferent pathways on speech perception have used contralateral ...

Corticofugal and Brainstem Functions Associated With Medial Olivocochlear Cholinergic Transmission

open access: yesFrontiers in Neuroscience, 2022
Cholinergic transmission is essential for survival and reproduction, as it is involved in several physiological responses. In the auditory system, both ascending and descending auditory pathways are modulated by cholinergic transmission, affecting the ...

Auditory cortex basal activity modulates cochlear responses in chinchillas. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: The auditory efferent system has unique neuroanatomical pathways that connect the cerebral cortex with sensory receptor cells. Pyramidal neurons located in layers V and VI of the primary auditory cortex constitute descending projections to ...

Neuronal regulation of the gut immune system and neuromodulation for treating inflammatory bowel disease

open access: yesFASEB BioAdvances, 2021
The gut immune system in the healthy intestine is anti‐inflammatory, but can move to a pro‐inflammatory state when the gut is challenged by pathogens or in disease.

The Effect of Sham Feeding on Neurocardiac Regulation in Healthy Human Volunteers

open access: yesCanadian Journal of Gastroenterology, 2007
BACKGROUND: Distension and electrical stimuli in the esophagus alter heart rate variability (HRV) consistent with activation of vagal afferent and efferent pathways. Sham feeding stimulates gastric acid secretion by means of vagal efferent pathways.

Efferent Auditory Pathways Inhibition in Turner syndrome.

open access: yesCoDAS, 2021
The goal of this study is to investigate the efferent auditory pathways inhibition in Turner's syndrome and to relate it to the cytogenetic profile.This is a cross-sectional study with a comparison group. A sample with 94 participants divided into two groups: The study group was a sample of 40 patients diagnosed with Turner's syndrome (17.6 years of ...

Corticofugal modulation of peripheral auditory responses

open access: yesFrontiers in Systems Neuroscience, 2015
The auditory efferent system originates in the auditory cortex and projects to the medial geniculate body, inferior colliculus, cochlear nucleus and superior olivary complex reaching the cochlea through olivocochlear fibers.

Subthalamic Nucleus: Neuroanatomical Review

open access: yesBrazilian Neurosurgery, 2017
Discovered in 1865 by Jules Bernard Luys, the subthalamic nucleus is a set of small nuclei located in the diencephalon, inferior to the thalamus and superior to the substantia nigra, that can be visualized in a posterior coronal section.
