Neuronal activity to environmental sounds when presented together with semantically related words : An MMN study on monolingual and bilingual processing of homophones

Neuronal activity of monolingual and bilinguals to environmental sounds and words that are semantically related to them were studied using the mismatch negativity (MMN) component of event-related potentials. MMN was expected to reflect the language selection process in bilinguals on the bases of sem...
