The influence of speech stimuli contrast in cortical auditory evoked potentials

open access: yesBrazilian Journal of Otorhinolaryngology, 2013
Studies about cortical auditory evoked potentials using the speech stimuli in normal hearing individuals are important for understanding how the complexity of the stimulus influences the characteristics of the cortical potential generated.

Direct Current Auditory Evoked Potentials During Wakefulness, Anesthesia, and Emergence from Anesthesia [PDF]

open access: yes, 2001
Direct current auditory evoked potentials (DC-AEPs) are a sensitive indicator of depth of anesthesia in ani-mals. However, they have never been investigated in humans. To assess the potential usefulness of DC-AEPs as an indicator of anesthesia in humans,

The effects of neck flexion on cerebral potentials evoked by visual, auditory and somatosensory stimuli and focal brain blood flow in related sensory cortices

open access: yesJournal of Physiological Anthropology, 2012
Background A flexed neck posture leads to non-specific activation of the brain. Sensory evoked cerebral potentials and focal brain blood flow have been used to evaluate the activation of the sensory cortex.

Newborns discriminate novel from harmonic sounds: a study using magnetoencephalography [PDF]

open access: yes, 2006
Objective: We investigated whether newborns respond differently to novel and deviant sounds during quiet sleep. Methods: Twelve healthy neonates were presented with a three-stimulus oddball paradigm, consisting of frequent standard (76%), infrequent

Auditory attention in childhood and adolescence: An event-related potential study of spatial selective attention to one of two simultaneous stories

open access: yesDevelopmental Cognitive Neuroscience, 2015
Auditory selective attention is a critical skill for goal-directed behavior, especially where noisy distractions may impede focusing attention. To better understand the developmental trajectory of auditory spatial selective attention in an acoustically ...

Gain modulation of synaptic inputs by network state in auditory cortex in vivo [PDF]

open access: yes, 2015
The cortical network recurrent circuitry generates spontaneous activity organized into Up (active) and Down (quiescent) states during slow-wave sleep or anesthesia.

Contralateral inhibition of click- and chirp-evoked human compound action potentials [PDF]

open access: yes, 2017
Cochlear outer hair cells (OHC) receive direct efferent feedback from the caudal auditory brainstem via the medial olivocochlear (MOC) bundle. This circuit provides the neural substrate for the MOC reflex, which inhibits cochlear amplifier gain and is ...

Analysis of gender based differences in auditory evoked potentials among healthy elderly population

open access: yesAdvanced Biomedical Research, 2014
Background: Influence of gender on auditory evoked potentials is contentious. Although there are quite a few studies documenting the gender as an influencing factor on auditory evoked potentials in younger subjects, but there is a lack of similar studies

Irregular speech rate dissociates auditory cortical entrainment, evoked responses, and frontal alpha [PDF]

open access: yes, 2015
The entrainment of slow rhythmic auditory cortical activity to the temporal regularities in speech is considered to be a central mechanism underlying auditory perception.

Acoustically evoked potentials in two cephalopods inferred using the auditory brainstem response (ABR) approach [PDF]

open access: yes, 2009
It is still a matter of debate whether cephalopods can detect sound frequencies above 400 Hz. So far there is no proof for the detection of underwater sound above 400 Hz via a physiological approach.
