background and aim: the double dichotic digit test (ddt) is a simple test for assessing and screening auditory processing system. the purpose of this study was to develope a double ddt, in persian language and find its basic norm values in girls aged 7 to 11 years. methods: the persian version of double ddt is composed of 3 different 25 numerical lists. numbers in each list were recorded dichot...
background and aim: auditory processing disorder and dyslexia have been reported by many studies as having high comorbidity. the purpose of the study was to investigate the effectiveness of central auditory processing rehabilitation program on speech reception in noise and dichotic listening in dyslexic students. the research was quasi-experimental, including a pretest, posttest and a control g...
OBJECTIVE The aim of this study was to evaluate the cochlear micromechanics and central auditory function in patients with type I diabetes mellitus and to identify the site of possible dysfunction. METHODS Cochlear activity was evaluated by recording distortion product otoacoustic emissions (DPOAEs). DPOAEs were performed using an ILO 92 Otodynamics Analyser. Functional changes in the retroco...
Proper structural organization of spiral ganglion (SG) innervation is crucial for normal hearing function. However, molecular mechanisms underlying the developmental formation of this precise organization remain not well understood. Here, we report in the developing mouse cochlea that deleted in colorectal cancer (Dcc) contributes to the proper organization of spiral ganglion neurons (SGNs) wit...
objectives: the aim of the present study was to assess the auditory lateralization ability in children with (central) auditory processing disorder. methods: participants were divided in two groups: 15 children with central auditory processing disorder (8-10 years) and 80 normal children (8-11 years) from both genders with pure-tone air-conduction thresholds better than 20 db hl bilaterally and ...
The ascending and descending projections of the central auditory system form multiple tonotopic loops. This study specifically examines the tonotopic pathway from the auditory thalamus to the auditory cortex and then to the auditory midbrain in mice. We observed the changes of receptive fields in the central nucleus of the inferior colliculus of the midbrain evoked by focal electrical stimulati...
One of the fascinating properties of the central nervous system is its ability to learn: the ability to alter its functional properties adaptively as a consequence of the interactions of an animal with the environment. The auditory localization pathway provides an opportunity to observe such adaptive changes and to study the cellular mechanisms that underlie them. The midbrain localization path...
Hierarchical models of auditory processing often posit that optimal stimuli, i.e., those eliciting a maximal neural response, will increase in bandwidth and decrease in modulation rate as one ascends the auditory neuraxis. Here, we tested how bandwidth and modulation rate interact at several loci along the human central auditory pathway using functional MRI in a cardiac-gated, sparse acquisitio...
There is substantial variability in speech recognition ability across patients with cochlear implants (CIs), auditory brainstem implants (ABIs), and auditory midbrain implants (AMIs). To better understand how this variability is related to central processing differences, the current electroencephalography (EEG) study compared hearing abilities and auditory-cortex activation in patients with ele...
