Previous research on event-related potentials (ERPs) on second language processing has revealed a great degree of plasticity in brain mechanisms of adult language learners. Studies with natural and artificial languages show that the N400 as well as the P600 component appear in learners after sufficient training. The present experiment tests if and which ERP components in response to syntactic and thematic processes generalize to unfamiliar lexical material in adult language learners. Learners of a miniature version of Japanese were presented with correct and incorrect sentences, half of which contained an unfamiliar word in the crucial sentence position. Incorrect sentences were either case-marking violations or word category violations. When all words were familiar, case-marking violations elicited a biphasic N400—P600 pattern and word category violations led to an early negativity that was followed by a P600. When the case violation occurred on an unfamiliar noun, only a P600 was seen. Word category violations that involved unknown verbs led to an early negativity and only to a reduced P600. The results suggest a high degree of nativelikeness for the learners during processing of familiar sentences. Unfamiliar words seem to entail additional processing costs and specifically lead to difficulties in the domain of case processing.

Abstract: We recorded reaction times (RTs) and event-related potentials (ERPs) in patients with unilateral lesions during a memory search task. Participants memorized faces or abstract words, which were then recognized among new ones. The RT deficit found in patients with left brain damage (LBD) for words increased with memory set size, suggesting that their problem relates to memory search. In contrast, the RT deficit found in patients with RBD for faces was apparently related to perceptual encoding, a conclusion also supported by their reduced P100 ERP component. A late slow wave (720-1720 ms) was enhanced in patients, particularly to words in patients with LBD, and to faces in patients with RBD. Thus, the slow wave was largest in the conditions with most pronounced performance deficits, suggesting that it reflects deficit-related resource recruitment.

Abstract. Objective: Fecal incontinence and constipation are common disorders in childhood. The enteric nervous system and the central nervous system are highly interactive along the brain-gut axis. The interaction is mainly afferent. These afferent pathways include centers that are involved in the central nervous processing of emotions as the mid/posterior insula and the anterior cingulate cortex. A previous study revealed altered processing of emotions in children with fecal incontinence. The present study replicates these results. Methods: In order to analyze the processing of emotions, we compared the event-related potentials of 25 children with fecal incontinence and constipation to those of 15 control children during the presentation of positive, negative, and neutral pictures. Results: Children with fecal incontinence and constipation showed altered processing of emotions, especially in the parietal and central cortical regions. Conclusions: The main study results of the previous study were replicated, increasing the certainty and validity of the findings.

Abstract. Objective: Daytime urinary incontinence (DUI) is common in childhood. The aim of the study was to neurophysiologically analyse the central emotion processing in children with DUI. Method: In 20 children with DUI (mean age 8.1 years, 55 % male) and 20 controls (mean age 9.1 years, 75 % male) visual event-related potentials (ERPs) were recorded after presenting emotionally valent (80 neutral, 40 positive, and 40 negative) pictures from the International Affective Picture System (IAPS) as an oddball-paradigm. All children received a full organic and psychiatric assessment. Results: Children with DUI did not differ significantly from controls regarding responses to emotional pictures in the frontal, central, and parietal regions and in the time intervals 250–450 ms, 450–650 ms, and 650–850 ms after stimulus onset. The patient group had more psychological symptoms and psychiatric comorbidities than the control group. Conclusions: EEG responses to emotional stimuli are not altered in children with DUI. Central emotion processing does not play a major role in DUI. Further research, including a larger sample size, a more homogeneous patient group (regarding subtype of DUI) or brain imaging techniques, could reveal more about the central processing in DUI.
