“…To overcome this problem, a few studies looking at the anatomical correlates of Fmθ used fMRI with simultaneous EEG recording. Despite the fact that fMRI scanner noise may affect mental concentration in some individuals when engaged in mental reasoning tasks (Pripfl et al, 2006), these fMRI studies clearly visualized Fmθ activity localized to the anteromedial frontal cortex (Gevins et al, 1997; Mizuhara et al, 2004; Sammer et al, 2007). …”

Frontal midline theta rhythm (Fmθ) appears widely distributed over medial prefrontal areas in EEG recordings, indicating focused attention. Although mental calculation is often used as an attention-demanding task, little has been reported on calculation-related activation in Fmθ experiments. In this study we used spatially filtered MEG and permutation analysis to precisely localize cortical generators of the magnetic counterpart of Fmθ, as well as other sources of oscillatory activity associated with mental calculation processing (i.e., arithmetic subtraction). Our results confirmed and extended earlier EEG/MEG studies indicating that Fmθ during mental calculation is generated in the dorsal anterior cingulate and adjacent medial prefrontal cortex. Mental subtraction was also associated with gamma event-related synchronization, as an index of activation, in right parietal regions subserving basic numerical processing and number-based spatial attention. Gamma event-related desynchronization appeared in the right lateral prefrontal cortex, likely representing a mechanism to interrupt neural activity that can interfere with the ongoing cognitive task.

“…Furthermore, it can induce stress and annoyance (e.g. Pripfl et al, 2006) which is prone to interact with affective stimulation. While sophisticated fMRI protocols have been developed to reduce the impact of acoustic scanner noise (Amaro et al, 2002;Blackman and Hall, in press;Griffiths et al, 2001;Hall et al, 1999;Hennel et al, 1999;Marcar et al, 2002;Obleser et al, 2007;Yetkin et al, 2003), the fMRI scanner environment (strict movement restrictions; claustrophobic situation) may still interfere with emotional processing at least in some humans.…”

Auditory cortex activation is modulated by emotion: A functional near-infrared spectroscopy (fNIRS) study

Visual emotional stimuli evoke enhanced activation in early visual cortex areas which may help organisms to quickly detect biologically salient cues and initiate appropriate approach or avoidance behavior. Functional neuroimaging evidence for the modulation of other sensory modalities by emotion is scarce. Therefore, the aim of the present study was to test whether sensory facilitation by emotional cues can also be found in the auditory domain. We recorded auditory brain activation with functional near-infrared-spectroscopy (fNIRS), a non-invasive and silent neuroimaging technique, while participants were listening to standardized pleasant, unpleasant, and neutral sounds selected from the International Affective Digitized Sound System (IADS). Pleasant and unpleasant sounds led to increased auditory cortex activation as compared to neutral sounds. This is the first study to suggest that the enhanced activation of sensory areas in response to complex emotional stimuli is apparently not restricted to the visual domain but is also evident in the auditory domain.

“…Additionally, we predict an effect of NS on the P1 response, because the differences in early ERP components between noise sensitive and non-sensitive individuals have previously been indicated. Evidence for this comes from scarce electrophysiological research on NS35 and annoyance caused by an unpleasant sound36.…”

Noise sensitive individuals are more likely to experience negative emotions from unwanted sounds and they show greater susceptibility to adverse effects of noise on health. Noise sensitivity does not originate from dysfunctions of the peripheral auditory system, and it is thus far unknown whether and how it relates to abnormalities of auditory processing in the central nervous system. We conducted a combined electroencephalography and magnetoencephalography (M/EEG) study to measure neural sound feature processing in the central auditory system in relation to the individual noise sensitivity. Our results show that high noise sensitivity is associated with altered sound feature encoding and attenuated discrimination of sound noisiness in the auditory cortex. This finding makes a step towards objective measures of noise sensitivity instead of self-evaluation questionnaires and the development of strategies to prevent negative effects of noise on the susceptible population.
