... (mean age 71.75 ± 6.81) did not receive AT. The mismatch negativity (MMN) test and matrix test were used to evaluate the effectiveness of AT. Tests were conducted for the study group before and after the AT. The tests were carried out for the control group at the same times with the study group...

... adopted an objective indicator of attentional processing, i.e. the mismatch negativity (MMN), to assess the attentional bias in patients with decompensated tinnitus. Three kinds of pure tones, D 1 (8,000 Hz), S (8,500 Hz) and D 2 (9,000 Hz), were used to induce event-related potentials (ERPs...

...Junming Chen; Suijun Chen; Yiqing Zheng; Yongkang Ou Mismatch negativity (MMN) has been widely used to study the function of central auditory processing in the elderly. However, current research has not yet considered the effect of noise and high-frequency hearing threshold on MMN in the elderly...

...Fawen Zhang; Chelsea Benson; Qian-Jie Fu A better understanding of melodic pitch perception in cochlear implants (CIs) may guide signal processing and/or rehabilitation techniques to improve music perception and appreciation in CI patients. In this study, the mismatch negativity (MMN) in response...

...Risto Näätänen; Kimmo Alho The mismatch negativity (MMN), elicited by any discriminable change in a repetitive sound even when this sound is not attended to, provides a pre-perceptual physiological measure of the accuracy of the central sound representation in the human brain. This accuracy, which...

...Valeria Csépe; Márk Molnár The mismatch negativity (MMN) is an event-related potential component that signifies neurophysiological processing of fine acoustic differences. The MMN indicates attention-independent change detection, reflects auditory sensory memory and provides a physiological measure...

...Paul Groenen; Ad Snik; Paul van den Broek Mismatch negativity (MMN) provides an objective measure for evaluating subjects with problems related to speech processing. For a valid neurophysiological profile of speech-processing mechanisms, an efficient procedure to elicit MMNs is needed...

... to explain this variation. Using mismatch negativity methods, this study explored associations between auditory sensory memory mechanisms and verbal working memory function in children with cochlear implants and a group of hearing controls of similar age. Whilst clear relationships were observed...

...Eila Lonka; Teija Kujala; Anne Lehtokoski; Reijo Johansson; Satu Rimmanen; Kimmo Alho; Risto Näätänen Speech-discrimination performance and the mismatch negativity (MMN) response elicited by vowel changes were used to track vowel-perception improvement of 5 adult cochlear-implant (CI) recipients...

...Rika Takegata; Simone Mariotto Roggia; Risto Näätänen The mismatch negativity (MMN) of the event-related potential has been purported to be an objective index of central auditory processing. The present study tested a new paradigm to measure the MMN responses to phonological changes in parallel...

... have emerged. These are called mismatch negativity (MMN) and late discriminative negativity (LDN). MMN, the brain’s automatic change-detection response in audition, has been intensively used in adults in both basic and clinical studies for longer than 20 years. LDN, on the other hand, was only recently...

... in an ascending order, whereas in the deviant pairs (p = 0.1), their order was reversed. Tone durations of 5 and 20 ms were employed in separate experiments. With the 20-ms stimulus duration, the change-specific mismatch negativity (MMN) component was elicited with all within-pair ISIs employed (0, 10, 30, 90 ms...
