Single-Voxel- versus Multi-Voxel-Protonen-MR-Spektroskopie bei verschiedenen intrakraniellen Läsionen
… Läsionen mittels Singelvoxel- versus Multivoxel-MR-Protonen-Spektroskopie signifikant unterschiedliche Ergebnisse bestehen. Untersucht wurden Hirntumoren der WHO-Grade 2 bis 4, Metastasen und fokal-entzündliche Läsionen. Zusammenfassend ist die Unterscheidung zwischen normalem und …

Approaches to Understanding the Function of Intrinsic Activity and its Relationship to Task-evoked Activity in the Human Brain
… dependent (BOLD) signal with fMRI to analyze the multivoxel activity patterns and FC structures of intrinsic activity, and compare them to those evoked by natural and synthetic visual stimuli.</p><p>In chapter 1, we review previous evidence of an association between intrinsic and task-evoked …

EXPLORING COVERT MOTOR PROCESSES: BEHAVIORAL INSIGHTS AND INNOVATIVE APPLICATIONS OF TRANSCRANIAL MAGNETIC STIMULATION
… and applies decoding techniques inspired by multivoxel pattern analysis (MVPA). This method captures distributed patterns of corticospinal activity, providing a more ecologically valid and multidimensional perspective on covert motor processes. The experimental studies discussed in this …

Thinking in patterns : representations in the neural basis of theory of mind
… of mental states. Specifically, I show that multivoxel pattern analysis (MVPA) can detect features of mental state representations (e.g., intent), and that these neural patterns are behaviorally relevant, including in autism spectrum disorders. In Chapter 3, I demonstrate that these brain …

Characterizing the spatiotemporal profile and the level of abstractness of action representations: neural decoding of magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) data
… representations are encoded. Using fMRI-based multivoxel pattern decoding, we aimed at dissociating the neural representations of states and action functions. Participants observed stills of objects (e.g., window blinds) that were in either open or closed states, and videos of actions involving …

Strength of family bond predicts disrupted neural habituation to visual familial threat in adolescence
BACKGROUND: Familial stressors, such as low family connectedness, confer risk for affective pathologies, yet little is known regarding how they uniquely impinge on neural systems involved in adaptive threat processing. METHODS: MVPA analysis of fMRI data was used in a novel way to measure disrupted …

The Role of the DLPFC in Bilingual and Monolingual Switching: Evidence from MVPA and tDCS
Previous research suggests that the bilingual experience controlling two languages may transfer to non-linguistic control tasks, resulting in a “bilingual advantage.” If this is the case, there should be a neural basis for this transfer (i.e., a region of the brain involved in both types of …
