Mapping the Spatial and Temporal Dynamics of Sensorimotor Integration During the Perception and Performance of Wallowing
… during the production and the perception tasks. Event related spectral perturbation (ERSP) analysis was used to identify spectral power within alpha and beta peaks of the mu cluster across time. Alpha and beta event-related desynchronization (ERD), indicative of somatosensory and motor activity, …

Alpha suppression as a neural marker of task demands in voluntary vs involuntary retrieval in older and younger adults
… EEG analysis, older adults showed greater alpha event-related desynchronization (ERD; a neural marker of memory reactivation) for paired than unpaired sounds at occipital sites, possibly reflecting visual reactivation of the associated pictures. Young adults did not show memory-related alpha ERD …

Developmental Plasticity of Language Representation in Healthy Subjects and Children with Medically Intractable Epilepsy
… beamformer analyses revealed low-beta event-related desynchronization (ERD) in the left inferior frontal lobe for verb generation. The paradigm was well-tolerated by all subjects. The third study involved assessment of expressive language lateralization in 25 healthy subjects, aged 5-18 …

Automatic Activation of Phonological Templates for Native but Not Nonnative Phonemes: An Investigation of the Temporal Dynamics of Mu Activation
… stream’s speech specific mechanisms from memory related ones in speech perception poses a complex problem. Here I argue that these processes may be disentangled from the viewpoint of the temporal dynamics of sensorimotor neural activation around a speech perception related event.</p> …

Investigating the effects of neuromodulatory training on autistic traits: a multi-methods psychophysiological study.
… more pronounced in neurotypical population, the event-related desynchronization (ERD) in low alpha declines. Chapter 3 was also the basis for the choice of pre/post assessment for chapter 4. In chapter 4 the multi-method physiological approach provided parallel physiological evidence for the …

Sensorimotor Modulations by Cognitive Processes During Accurate Speech Discrimination: An EEG Investigation of Dorsal Stream Processing
… Time frequency (ERSP) analysis evaluated task-related changes in focal activation patterns with phase coherence measures employed to track patterns of information flow across the dorsal stream. ERSP decomposition of mu clusters revealed event-related desynchronization (ERD) in beta and alpha …

Behavioural and neurophysiological measures of haptic feedback during a drilling simulation
… measures and demonstrated greater desynchronization in trials with haptic feedback, as compared to trials without haptic feedback. Large effect sizes were found between haptic and non-haptic trials in the alpha frequency band (8-13 Hz). This work provides evidence that task-relevant …

Investigation of differences in cortical activation during wrist flexion and extension performed under real, passive and motor imagined paradigms
… difficulty, movement dynamics, movement related cortical potential (MRCP), event related desynchronization and synchronization (ERD/ERS), and phase locking value (PLV) were measured. Each measurement examines a different aspect of the cortical activation present in the brain, during the …
