The neural bases of (written) language recovery and learning
- Identifying the neural substrates that support recovery of written language functions in individuals with post-stroke dysgraphia and dysgraphia associated with primary progressive aphasia
- Investigating the neural mechanisms that support recovery. We are investigating this at multiple scales: macro, meso and micro (voxel to voxel), examining changes in local aspects of neural representations as well as inter-module and whole-brain connectivity.
- Orthographic learning: Investigating the neural substrates involved in the normal learning of word spellings.
- Investigating both the functional and structural connectivity networks that support written language processing, learning and recovery.
Optimizing dysgraphia treatment
- Applying principles of learning theory to maximize the benefits of rehabilitation in acquired dysgraphia.
- Identifying pre-treatment predictors of responsiveness to dysgraphia treatment
Written language: processes and representations
- The internal structure and content of orthographic representations: What do we know when we know the spellings of words?
- Using patterns of errors in acquired dysgraphia as well as neural data (multi-voxel fMRI approaches) to investigate the nature and content of orthographic representations
- Understanding the functional architecture of reading and spelling: The operations of long term and working memory components of reading and spelling, their neural instantiations and their relationships to other language and cognitive systems
Spoken Language: Processes and representations
- Elucidating the processes involved in going from a thought/concept to speech production.
- Identifying the neural substrates of lexical processes involved in spoken word comprehension and production.
- Understanding the processing and representational relationships between written and spoken language in the literate mind/brain. To what extent are processes shared between spoken and written language (e.g, working memory)? To what extent is written language autonomous from spoken language?
Representation and plasticity in the somatosensory system
- The reorganization of somatosensory perceptions subsequent to neural injury or abnormal development
- Somatosensory frames of reference
- Cross-modal attention: integration and competition across sensory modalities
