    Auditory Environment and Change Detection as Indexed by the Mismatch Negativity (MMN)

    Mismatch negativity (MMN) is an automatic event-related brain potential (ERP) that reflects a change in auditory stimulation and provides a unique measure of central sound representation. The electrically regi...

    Neuromagnetic Responses of the Human Auditory Cortex to Different Types of Infrequent Deviant Stimuli

    An infrequent “deviant” auditory stimulus presented among repetitive “standard” stimuli elicits a specific EEG signal termed the mismatch negativity (MMN; Näätänen et al., 1978) which is not seen in responses ...

    The Orienting Response; A Combination of Informational and Energetical Aspects of Brain Function

    The orienting response (OR) or orienting reflex continues to be one of the most central concepts of psychophysiology. In a way, this concept has become even too popular. It has grown too broad to serve as a ve...
