“…Model 2 explains deactivation as a consequence of cross-modal inhibition mechanisms that reduce potentially distracting neural processes (Laurienti, et al 2002). With respect to the present study, the Model 2 advocates that deactivation in the posterior insula, PCL, ACG, MTG, CG, PHG, PCG, and precuneus during WM but less so during VA is a result of direct neural inhibition.…”

“…Similarly, fMRI studies using cross-modal stimuli showed deactivation of the auditory cortices during visual stimulation, while deactivation of the visual cortices occurred during auditory stimulation (Laurienti, et al 2002;Lewis, et al 2000). These findings suggest that the concomitant deactivation could represent cross-modal inhibition (an active suppression of neural activity), to minimize potentially distracting, taskirrelevant neural processes.…”

This parametric functional magnetic resonance imaging (fMRI) study investigates the balance of negative, and positive fMRI signals in the brain. A set of visual attention (VA) and of working memory (WM) tasks with graded levels of difficulty was used to deactivate separate, but overlapping networks that include the frontal, temporal, occipital, and limbic lobes; regions commonly associated with auditory and emotional processing. Brain activation (% signal change, and volume) was larger for VA tasks than for WM tasks, but deactivation was larger for WM tasks. BOLD responses crosscorrelated strongly in the deactivated network during VA but less so during WM. The variability of the deactivated network across different cognitive tasks supports the hypothesis that global CBF vary across different tasks, but not between conditions of the same task. The task-dependent balance of activation and deactivation might allow maximization of resources for the activated network.

“…In reference to this deactivated area, Levitin & Menon (2003) reported greater activation in a similar region in the cuneus and superior and middle occipital gyri among other nearby areas in the presence of scrambled music compared to non-scrambled music. From this finding the authors did not infer this activation as reflecting processing of scrambled music, since many of these regions are known to be deactivated during both auditory and visual processing (Laurienti, Burdette, Wallace, Yen, Field, & Stein, 2002). In the study carried out by Alluri et al (2012), the left-right MTG (with leftward bias) seemed to be implicated in the perceptual processing of timbral features of the Piazzolla piece that was used in the present study.…”

Sivumäärä -Number of pages 70Tiivistelmä -Abstract Working memory (WM) is at the core of any cognitive function as it is necessary for the integration of information over time. Despite WM's critical role in high-level cognitive functions, its implementation in the neural tissue is poorly understood. Preliminary studies on auditory WM show differences between linguistic and musical memory, leading to the speculation of specific neural networks encoding memory for music. Moreover, in neuroscience WM has not been studied in naturalistic listening conditions but rather in artificial settings (e.g., n-back and Sternberg tasks). Western tonal music provides naturally occurring motivic repetition and variation, recognizable units serving as WM trigger, thus allowing us to study the phenomenon of motif-tracking in the context of real music. Adopting a modern tango as stimulus, behavioural methods were used to identify the stimulus motifs and build a time-course predictor of WM neural responses. This predictor was then correlated with the participants' functional magnetic resonance imaging (fMRI) signal obtained during a continuous listening condition. Neural correlates related to the sensory processing of a set of musical features were filtered out from the brain responses to music to aid in the exclusive recruitment of executive processes of music-related WM. Correlational analysis revealed a widely distributed network of cortical and subcortical areas, predominantly right-lateralized, responding to the WM condition, including ventral and dorsal areas in the prefrontal cortex, basal ganglia, and limbic areas. Significant subcortical processing areas, active in response to the WM condition, were pruned with the removal of the acoustic content, suggesting these music-related perceptual processing areas might aid in the encoding and retrieval of WM. The pattern of dispersed neural activity indicates WM to emerge coherently from the integration of distributed neural activity spread out over different brain subsystems (motoric-, cognitive-and sensory-related areas of the brain).Asiasanat -Keywords working memory; cognitive neuroscience; music; musical motifs; functional magnetic resonance imaging ( Lashley was attempting to identify the locus of memory within the cortex, and, to do so, first trained rats to run mazes, and then removed various cortical regions. He allowed the animals to recover and tested the retention of the maze-running skills. To his surprise it was not possible to find a particular region corresponding to the ability to remember the way through a maze. Instead all the rats which had had cortex regions removed suffered some kind of impairment, and the extent of the impairment was roughly proportional to the amount of cortex taken off. Removing cortex damaged the motor and sensory capacities of the animals, and they would limp, hop, roll, or stagger, but somehow they always managed to traverse the maze. So far as memory 'as concerned, the cortex appeared to be equipotential, that is, with all regions of eq...

“…Task-related decreases in BOLD contrast (deactivations) have been reported in fMRI studies [14][15][16][17] and have been correlated with decreased blood oxygenation and neural suppression [17]. Functional neuroimaging studies could therefore provide the desired converging evidence by determining whether a stimulus category, such as faces, evokes spatially discrete BOLD contrast activations and deactivations.…”

Faces evoke spatially differentiated patterns of BOLD activation and deactivation

Using fMRI techniques sensitive to blood oxygen-level dependent (BOLD) contrast, we measured brain activity in participants (n ¼ 8) as they viewed images of faces presented periodically within a continuously changing montage of common objects. Consistent with prior studies, we identi¢ed regions of ventral extrastriate cortex, primarily in the fusiform and inferior temporal gyri and nearby cortex, that were activated by faces as measured by an increase in BOLD signal. In addition, we made the novel observation that faces deactivated other areas of ventral extrastriate cortex, primarily in the lingual and parahippocampal gyri and medial to activations. These deactivated regions, identi¢ed by a decrease in BOLD signal, may re£ect populations of neurons that decrease their activity when faces appear, possibly as a consequence of category-speci¢c inhibition.
