Pre-attentive cortical processing of behaviorally perceptible spatial changes in older adults—a mismatch negativity study
From behavioral studies it is known that auditory spatial resolution of azimuthal space declines over age. To date, it is not clear how age affects the respective sensory auditory processing at the pre-attentive level. Here we tested the hypothesis that pre-attentive processing of behaviorally perceptible spatial changes is preserved in older adults. An EEG-study was performed in older adults (...
متن کاملEvidence for the role of German final devoicing in pre-attentive speech processing: a mismatch negativity study
Results of a mismatch negativity experiment are reported in which the pre-attentive relevance of the German phonological alternation of final devoicing (FD) is shown in two ways. The experiment employs pseudowords. (1) A deviant [vus] paired with standard /vuzə/ did not show a mismatch effect for the voicing change in /z/ versus [s] because the two can be related by FD. When standard and devian...
متن کاملIs pre-attentive processing compromised by prolonged wakefulness? Effects of total sleep deprivation on the mismatch negativity.
We investigated the potential influence of sustained wakefulness on pre-attentive capacities by recording the mismatch negativity (MMN), an electrophysiological manifestation associated with nonintentional detection of auditory oddball stimuli. The MMN was elicited by pitch deviants presented to both ears via earphones, at the beginning of a total sleep deprivation session (baseline), after 24 ...
متن کاملThe neural circuitry of pre-attentive auditory change-detection: an fMRI study of pitch and duration mismatch negativity generators.
Electrophysiological studies have revealed a pre-attentive change-detection system in the auditory modality. This system emits a signal termed the mismatch negativity (MMN) when any detectable change in a regular pattern of auditory stimulation occurs. The precise intracranial sources underlying MMN generation, and in particular whether these vary as a function of the acoustic feature that chan...
متن کاملMismatch negativity
New perspectives in cognitive1,2 and clinical3,4 neuroscience have been opened up with the recent discovery of mismatch negativity (MMN),5 an auditory event-related brain potential (ERP) elicited by infrequent deviant sounds occurring in a sequence of repeated tones.1 The MMN appears as a negative displacement on the ERP to deviant sounds relative to that to standard sounds, with a peak latency...
