    The neural basis of absolute pitch (AP), the ability to effortlessly identify a musical tone without an external reference, is poorly understood. One of the key questions is whether perceptual or cognitive processes underlie the phenomenon, as both sensory and higher-order brain regions have been associated with AP. To integrate the perceptual and cognitive views on AP, here, we investigated joint contributions of sensory and higher-order brain regions to AP resting-state networks. We performed a comprehensive functional network analysis of source-level EEG in a large sample of AP musicians (n = 54) and non-AP musicians (n = 51), adopting two analysis approaches: First, we applied an ROI-based analysis to examine the connectivity between the auditory cortex and the dorsolateral prefrontal cortex (DLPFC) using several established functional connectivity measures. This analysis is a replication of a previous study which reported increased connectivity between these two regions in AP musicians. Second, we performed a whole-brain network-based analysis on the same functional connectivity measures to gain a more complete picture of the brain regions involved in a possibly large-scale network supporting AP ability. In our sample, the ROI-based analysis did not provide evidence for an AP-specific connectivity increase between the auditory cortex and the DLPFC. The whole-brain analysis revealed three networks with increased connectivity in AP musicians comprising nodes in frontal, temporal, subcortical, and occipital areas. Commonalities of the networks were found in both sensory and higher-order brain regions of the perisylvian area. Further research will be needed to confirm these exploratory results.

  • A reevaluation of the electrophysiological correlates of absolute pitch and relative pitch: No evidence for an absolute pitch-specific negativity
    Item type: Journal Article

    Musicians with absolute pitch effortlessly identify the pitch of a sound without an external reference. Previous neuroscientific studies on absolute pitch have typically had small samples sizes and low statistical power, making them susceptible for false positive findings. In a seminal study, Itoh et al. (2005) reported the elicitation of an absolute pitch-specific event-related potential component during tone listening — the AP negativity. Additionally, they identified several components as correlates of relative pitch, the ability to identify relations between pitches. Here, we attempted to replicate the main findings of Itoh et al.'s study in a large sample of musicians (n = 104) using both frequentist and Bayesian inference. We were not able to replicate the presence of an AP negativity during tone listening in individuals with high levels of absolute pitch, but we partially replicated the findings concerning the correlates of relative pitch. Our results are consistent with several previous studies reporting an absence of differences between musicians with and without absolute pitch in early auditory evoked potential components. We conclude that replication studies form a crucial part in assessing extraordinary findings, even more so in small fields where a single finding can have a large impact on further research.

  • Exploring psychophysiological indices of disruptive behavior disorders and their subtypes of aggression
    Item type: Journal Article

    Background: Psychophysiological measures of arousal are often considered as potential biomarkers for disruptive behavior disorder (DBD). Nevertheless, the evidence is mixed, possibly reflecting the heterogeneity of DBD and different subtypes of aggression. Additionally, arousal measures of the central nervous system (e.g. electroencephalogram: EEG) are underrepresented compared to peripheral ones (heart rate: HR; skin conductance: SC). Methods: We recorded HR, SC, and EEG (frequency band power at three electrodes Fz, Cz, Pz) in 49 participants with DBD, and 15 typically developing peers during two resting state and an emotional task condition. Group differences were assessed by a repeated measure ANOVA and regression analyses were applied to evaluate subtype-specific patterns. Results: Our results showed higher mean HR activity in DBD participants, which was however driven by medicated participants and no significant group differences were found for SC. Interestingly, a significant group x frequency band interaction emerged for the EEG. DBD youth showed lower alpha activity. Regression analyses showed that higher theta and lower alpha band activity were related to more general aggression scores and higher delta and lower beta activity predicted proactive aggression. Conclusions: The lack of robust and significant differences for peripheral measurements (HR and SC) fits with previous mixed findings for externalizing disorders. Our results suggest that EEG measurements might be more sensitive to detect group differences and higher delta and lower beta activity might represent an index of a proactive subtype of aggression.
