OBJECTIVE We measured late cortical potentials in a psychophysical procedure for binaural unmasking of a dichotically-embedded pitch. METHODS Late-latency auditory evoked potentials were measured from 128 recording channels in 13 healthy subjects. Control stimuli consisted of 500 ms segments of broadband acoustic noise presented identically to both ears via earphones, evoking a perception of ...

The human auditory cortex plays a special role in speech recognition. It is therefore necessary to clarify the functional roles of individual auditory areas. We applied functional magnetic resonance imaging (fMRI) to examine cortical responses to speech sounds, which were presented under the dichotic and diotic (binaural) listening conditions. We found two different response patterns in multipl...

UNLABELLED In the elderly, the results of central auditory pathways behavioral assessments are considered to be difficult to read because of the possible interference of peripheral auditory pathway involvement. AIM Assess the efficacy of the central auditory function in elderly patients who do not complain of hearing. MATERIALS AND METHODS Case study involving 40 individuals within the age ...

OBJECTIVE To investigate central auditory processing in children with unilateral stroke and to verify whether the hemisphere affected by the lesion influenced auditory competence. METHOD 23 children (13 male) between 7 and 16 years old were evaluated through speech-in-noise tests (auditory closure); dichotic digit test and staggered spondaic word test (selective attention); pitch pattern and ...

In the elderly, the results of central auditory pathways behavioral assessments are considered to be difficult to read because of the possible interference of peripheral auditory pathway involvement. Aim: Assess the efficacy of the central auditory function in elderly patients who do not complain of hearing. Materials and Methods: Case study involving 40 individuals within the age range of 60 t...

A prior study found a selective deficit in verbal working memory in a subgroup of patients with schizophrenia who performed as well as healthy controls on a screening test of attention and auditory perception [Arch. Gen. Psychiatry 55 (1998) 1093]. Given the importance of defining pathophysiologically distinct subtypes of schizophrenia, the present study aimed to replicate and extend this findi...

The presentation of visual stimuli of moving mouth is known to affect the phoneme perception of the auditory stimuli during natural speech, and provides important insights into the scientific and technological study of speech. In order to investigate the laterality of the audio-visual integration we studied the relationship between the McGurk effect (McGurk and McDonaold 1976) and Right Ear Adv...

Objectives: The aim of this research is designing a computerized program, in game format, for working memory training in mild intellectual disabled children. Methods: 24 students participated as test and control groups. The auditory and visual-spatial WM were assessed by primary test, which included computerized Wechsler numerical forward and backward sub- tests, and secondary tests, which c...
