The neuroscientific examination of music processing in audio-visual contexts offers a valuable framework to assess how auditory information influences the emotional encoding of visual information. Using fMRI during naturalistic film viewing, we investigated the neural mechanisms underlying the effect of music on valence inferences during mental state attribution. Thirty-eight participants watched the same short-film accompanied by systematically controlled consonant or dissonant music.

Although the brain underpinnings of social cognition have been extensively studied, no empirical work has yet examined the impact of musical structure manipulation on the neural processing of emotional valence during mental state inferences. We used a novel sound-based theory-of-mind paradigm in which participants categorized stimuli of different sensory dissonance level in terms of positive/negative valence.

Despite the existence of numerous neuroimaging studies demonstrating significant brain functional alterations in substance users, only a few studies have tried to analyze the association between the duration of abstinence and brain metabolism within substance users. The aim of this study was to examine the association between resting-state regional brain metabolism (measured with 18F-fluordeoxyglucose Positron Emission Tomography (FDGPET) and duration of drug abstinence in a sample of 49 abstinent polysubstance users. PET images were pre-processed and analyzed using SPM5 and SPSS 15.

The study of substance-abuse-related neuropsychological deficits and brain alterations may provide a better understanding of the neuroadaptations associated with addiction. In this study we investigated the association between performance on neuropsychological tests of cold and hot executive functions and regional brain metabolism. Measured with positron emission tomography (PET), in a sample of 49 substance-dependent individuals (SDI).
