The field of neuroimaging has experienced a tremendous boom due to technological advances in the last ten years and this is also reflected in the electroencephalography / event-related potentials (EEG/ERP) method. This contribution provides an overview of the main EEG/ERP hardware systems and software development currently on the market and the benefits of such technology for the study of language issues. We discuss the “added-value” such technology brings to the research of language and the possibilities of combining various neuroimaging technique with emphasis on the integration of EEG/ERP and functional magnetic resonance imaging (fMRI). Our contribution ends with a look at what we think may be the methodologies that drive the field forward in the not too distant future.

The neuronal correlate of a rare explicit bidirectional synesthesia was investigated with numerical and physical size comparison tasks using both functional magnetic resonance imaging and event-related potentials. Interestingly, although participant I.S. exhibited similar congruity effects for both tasks at the behavioral level, subsequent analyses of the imaging data revealed that different brain areas were recruited for each task, and in different time windows. The results support: (1) the genuineness of bidirectional synesthesia at the neuronal level, (2) the possibility that discrepancy in the neuronal correlates of synesthesia between previous studies might be task-related, and (3) the possibility that synesthesia might not be a unitary phenomenon.

Background Lack of an olfactory bulb (OB) is typically associated with anosmia. Methods We present a patient with subnormal olfactory function in whom the OB could not be detected with magnetic resonance imaging (MRI). Results Olfactory function was evaluated on two occasions. Orthonasal olfactory function was assessed with the “Sniffin’ Sticks” test providing a score equivalent to hyposmia. Retronasal olfactory function was studied with “smell powders” indicating a decreased, but not absence of, olfactory function. Importantly, chemosensory event-related potentials were clearly present in response to olfactory and trigeminal stimuli. Conclusion This indicates that olfactory function may be present in some subjects even when an OB can not be detected with MRI.
