Cognitive Neuropsychology
Parts of the left ventral visual pathway are engaged selectively during the perception of words, letterstrings, and even single letters. While studies have shown overlap between activations for letters and characters across writing systems, they adopted group analyses with very limited spatial resolution, or used words and letterstrings, which have been shown to activate different regions from ...

NeuroReport 5, 2381-2384 (1994) WHEN two concurrent sensorimotor tasks require separate responses, selection of the first response generally delays selection of the second. Dual-task performance was examined in four patients who had undergone surgical transection of the forebrain commissures including the corpus callosum. One light flash was presented to each visual field in succession, and pat...

The neural basis of auditory perception can be investigated non-invasively by recording event-related brain potentials (ERPs) during auditory stimulation.1 ERPs can be conceptualized as a sequence of components each with its own set of neural generators and reflecting different psychological functions.2 The ERP component termed the mismatch negativity (MMN) reflects a pre-attentive auditory dev...

In event-related potentials (ERPs) studies, recognition memory is associated with two positivities: one over parietal regions, and one over frontal regions. With nameable neutral stimuli, such as words or common objects, the parietal effect is usually left lateralized, and the frontal effect is usually right lateralized. We investigated the lateralization of these effects for nonnameable emotio...

A deviant sound in a sequence of repeating (standard) sounds elicits the mismatch negativity (MMN) component in the event-related brain potential (ERP) recorded from the scalp.1 The MMN is elicited even when the subject is instructed to ignore the auditory stimuli and attend to other stimuli. In the ERP to deviant sounds, the MMN overlaps with the negative N1 (peak latency about 100 ms from sti...
