A New Eye On Semantics: Probing the Spatiotemporal Brain Dynamics Underlying Natural Reading
… the influence of task and context on the semantic processing of single words in isolation and in a sentence context. In one study, I considered task effects on single-word semantic representations using multivariate pattern analysis. In two further studies, I tested whether sentence …

Uncovering Dynamic Semantic Networks in the Brain Using Novel Approaches for EEG/MEG Connectome Reconstruction
… unresolved predictions of recent models of the semantic brain system, such as the hub-and-spokes model. In particular, we tackle different aspects of the hypothesis that a widespread network of interacting heteromodal (hub(s)) and unimodal (spokes) cortices underlie semantic cognition. For this …

Social-semantic knowledge and behavioural changes in frontotemporal dementia
Key insights into the organisation of semantic memory in the brain have been derived from semantic dementia, a subtype of frontotemporal dementia (FTD) associated with a degradation of conceptual knowledge following atrophy in the anterior temporal lobes (ATLs). Recent research in FTD has begun to …

Development of novel multidimensional pattern-based EEG/MEG connectivity methods and their application to investigate the semantic brain network
… methods to gain novel insights into the brain semantic network. In order to do so, I compared two semantic visual word processing tasks, varying the depth of semantic processing of words by contrasting a semantic decision (SD) and a lexical decision (LD) task. I used both conventional …

A comparison of imaging modalities and decoding methods for detecting semantic information in the brain
Representation of semantic information enables us to engage with the world in a meaningful way – to comprehend and produce language, identify and use objects, and understand and participate in events that involve us. Our understanding of where in the brain semantic information is represented has …

The contributions of posterior lateral temporal cortex to language and control networks
… challenge. In recent years, the Controlled Semantic Cognition framework has offered an account of the neural correlates of representation and control of meaningful information. The context-independent storage of semantic representations is subserved by the bilateral anterior temporal lobe …
