The neuronal basis of visual word recognition

Within the Marie Curie 'Research Training Network: Language and Brain' [RTN:LAB] I used Magnetoenchephalography (MEG) to investigate the spatiotemporal evolution of cortical activity during the processing of words presented left or right from a central fixation, developing new methods for the acquisition and analysis of neuromagnetic signals (e.g., beamforming and virtual electrodes). Results highlight the role, within the left hemisphere, of top-down influences from motor-articulatory regions to visual-recognition areas.

I have explored the impact of auditory deprivation on word recognition, using coregistration of functional MRI signal and Electroencephalography (WoRHD project, funded within the Marie Curie Reintegration Grant schema).
