Somatosensory demands modulate muscular beta-oscillations independent of motor demands
Freek van Ede (and Eric Maris)

ABSTRACT: Neural oscillations in the beta-band occur coherently throughout a widely distributed network comprising somatomotor cortices, cerebellum, thalamus, basal ganglia and spinal cord (evidenced from beta-oscillations in muscle activity). In accordance with the anatomy of this network, these oscillations have traditionally been associated with motor function. At the same time, it has recently become clear that beta-oscillations recorded over the contralateral primary somatomotor cortex also contribute to the perception of touch (independent of movement). We investigated whether these somatosensory-relevant beta-oscillations are actually part of this large-scale coherent beta-network. If so, cortical modulations associated with somatosensory demands – in anticipation and during the processing of tactile stimuli – should also be observed in non-somatosensory parts of the network (given interareal coupling). To address this, we investigated oscillatory muscle activity recorded at the flexors of the forearms while human subjects performed cued somatosensory identification tasks. We observe reliable beta-modulations of oscillatory muscle activity (independent of motor demands) consistent with the hypothesized propagation through this network from cortex to muscle. This confirms that the somatosensory-relevant beta-oscillations are part of the large-scale somatomotor network, placing touch perception as a fundamental computation within this network. In addition, these data reveal that, despite behavioral-demands, neural activity in populations involved in somatosensation and action cannot occur independently, not even at the level of the muscles.

    Stimulus presentation controlled by a realtime EEG signal
    Ilia Korjoukov

    Ilia and his collegue Timo will present an "alpha game" which they created. They will treat us to a demo of the game, present an new algorithm for phase prediction in a realtime EEG signal and show simulations with offline data and discuss what software/hardware capacities are necessary for phase-locked stimulus presentation.

    Effective connectivity of physiological speech production and its alteration in stuttering and Parkinson's disease 

    Abstract
    Speech production offers the opportunity to study complex brain networks that encompass executive, motor, sensory and associative cortices. In this talk I will present functional imaging data on the preparation of these networks and how the setup is affected by alterations in subcortical and cortical dopamine concentration. A second focus will be on auditory-motor interactions underlying auditory feedback integration in health and disease. Finally, I will discuss factors that contribute to the pronounced lateralization of speech production ranging from development to local oscillations.
