Abstract& The present study investigated simultaneous processing of language and music using visually presented sentences and auditorily presented chord sequences. Music-syntactically regular and irregular chord functions were presented synchronously with syntactically correct or incorrect words, or with words that had either a high or a low semantic cloze probability. Music-syntactically irregular chords elicited an early right anterior negativity (ERAN). Syntactically incorrect words elicited a left anterior negativity (LAN). The LAN was clearly reduced when words were presented simultaneously with music-syntactically irregular chord functions. Processing of high and low cloze-probability words as indexed by the N400 was not affected by the presentation of irregular chord functions. In a control experiment, the LAN was not affected by physically deviant tones that elicited a mismatch negativity (MMN). Results demonstrate that processing of musical syntax (as reflected in the ERAN) interacts with the processing of linguistic syntax (as reflected in the LAN), and that this interaction is not due to a general effect of deviance-related negativities that precede an LAN. Findings thus indicate a strong overlap of neural resources involved in the processing of syntax in language and music. &

Oxytocin (OT) enhances social behaviors such as attachment and parental caretaking. Neural correlates of maternal attachment are found in reward-related brain regions, for example, in the globus pallidus (GP). The present work investigates the effects of OT on the neural correlates of parental attachment. Fathers viewed pictures of their own child (oC), a familiar child (fC), and an unfamiliar child (uC) after intranasal application of OT vs placebo. OT reduced activation and functional connectivity of the left GP with reward- and attachment-related regions responsive to pictures of the oC and the uC. The present results emphasize the key role of OT in human parental attachment and suggest that OT reduces neural reactivity to social cues as a function of social salience. Our results together with previous findings speak to a selective reduction of neural reactivity to social stimuli, irrespective of their valence. We argue that one major pathway by which OT exerts its positive effects on affiliative and social behaviors is the attenuation of automatic neural responses, which in turn leads to increased approach behaviors and decreased social avoidance.

A pedophilic disorder is recognized for its impairment to the individual and for the harm it may cause to others. Pedophilia is often considered a side issue and research into the nature of pedophilia is delayed in comparison to research into other psychiatric disorders. However, with the increasing use of neuroimaging techniques, such as functional and structural magnetic resonance imaging (sMRI, fMRI), together with neuropsychological studies, we are increasing our knowledge of predisposing and accompanying factors contributing to pedophilia development. At the same time, we are faced with methodological challenges, such as group differences between studies, including age, intelligence, and comorbidities, together with a lack of careful assessment and control of child sexual abuse. Having this in mind, this review highlights the most important studies investigating pedophilia, with a strong emphasis on (neuro-) biological studies, combined with a brief explanation of research into normal human sexuality. We focus on some of the recent theories on the etiology of pedophilia such as the concept of a general neurodevelopmental disorder and/or alterations of structure and function in frontal, temporal, and limbic brain areas. With this approach, we aim to not only provide an update and overview but also a framework for future research and to address one of the most significant questions of how pedophilia may be explained by neurobiological and developmental alterations.

To comprehend emotional prosodic cues in speech is a critical function of human social life. However, it is common in everyday communication that conflicting information in emotional prosody and semantic content co-occur. Here, we sought to specify brain regions involved in conflict monitoring of these interfering communication channels. By means of functional magnetic resonance imaging, we obtained signal increases in the right dorsal anterior cingulate cortex and right superior temporal gyrus (STG) and superior temporal sulcus when participants listened to incongruous compared with congruous sentences. Moreover, valence-specific effects were found in the left inferior frontal gyrus and left STG for happily intoned sentences expressing a negative content. The left caudate nucleus along with the thalamus was active when angrily intoned sentences were coupled with positive semantic content. Our results suggest a brain network that monitors conflict in emotional prosody and emotional semantic content comprising of medial prefrontal areas that have previously been associated with cognitive conflict processing. Furthermore, our study extends the knowledge of these processes by suggesting valence-specific differences of emotional conflict processing.

Objective: Compare the processing of music-syntactic irregularities and physical oddballs between cochlear implant (CI) users and matched controls.Methods: Musical chord sequences were presented, some of which contained functionally irregular chords, or a chord with an instrumental timbre that deviated from the standard timbre.Results: In both controls and CI users, functionally irregular chords elicited early (around 200 ms) and late (around 500 ms) negative electric brain responses (early right anterior negativity,ERAN and N5). Amplitudes of effects depended on the degree of music-syntactic irregularity in both groups; effects elicited in CI users were distinctly smaller than in controls. Physically deviant chords elicited a timbremismatch negativity (MMN) and a P3 in both groups, again with smaller amplitudes in CI users.Conclusions: ERAN and N5 (as well as timbre-MMN and P3), can be elicited in CI users. Although amplitudes of effects were considerably smaller in the CI group, the presence of MMN and ERAN indicates that neural mechanisms of both physical and musicsyntactic irregularity-detection were active in this group.
