    Motor intracortical excitability before speech onset in adults who stutter

    A. Elfers, S. Hommel, N. Neef, AW. von Gudenberg, W. Paulus, M. Sommer (Bad Emstal, Germany)

    Objective: A core feature of persistent developmental stuttering is the paroxysmal, transient, involuntary loss of speech motor control. However, the neurophysiology of stuttering remains largely…

    Impaired intracortical inhibition predicts response to medication in Parkinson’s disease patients

    SR. Filipović, A. Kačar, S. Milanović, M. Ljubisavljević, VS. Kostić (Beograd, Serbia)

    Objective: To check whether measures of motor cortex excitability and plasticity are associated with clinical response to dopaminergic treatment in Parkinson’s disease (PD) patients. Background:…

    Impaired LTP-like plasticity in Parkinson’s Disease can be restored by γ-transcranial alternating current stimulation

    A. Guerra, A. Suppa, F. Asci, V. D'Onofrio, V. Sveva, M. Bologna, A. Berardelli (Rome, Italy)

    Objective: To test whether the co-stimulation γ-transcranial alternating current stimulation (γ-tACS)-intermittent theta burst stimulation (iTBS) is effective in improving the impaired long-term potentiation (LTP)-like plasticity…

    Cortical gamma oscillations as biomarkers for levodopa-induced dyskinesia

    C. Güttler, J. Altschüler, K. Tanev, S. Böckmann, JK. Haumesser, A. Kühn, C. van Riesen (Berlin, Germany)

    Objective: The aim of our study was to characterize cortical neuronal network activity in levodopa-induced dyskinesia in order to better understand the underlying pathophysiology and…

    To respond or not to respond to paired associative stimulation: proof of intervention by cerebello-cortical circuit

    A. Kishore, P. James, P. Rajeswari, A. Thejaus, G. Sarma, S. Meunier (Trivandrum, India)

    Objective: To test whether the non-responder or responder status of primary motor cortex (M1) to an LTP- inducing paired associative stimulation (PAS) protocol in healthy…

    The dopamine receptor antagonist haloperidol enhances beta and gamma oscillations and bursts in the motor cortex

    M. Alam, T. Doll, J. Krauss, K. Schwabe (Hannover, Germany)

    Objective: We aimed to investigate the changes in oscillatory activity in the motor cortex (MCtx) and the sensorimotor cortex (SMCtx) of rats after acute injection…

    Parkinsonism alters directed connectivity in the cortico-subthalamo-pallidal circuit

    D. Escobar Sanabria, L. Johnson, Y. Yu, J. Zhang, S. Nebeck, Z. Busby, G. Molnar, J. Vitek (Minneapolis, MN, USA)

    Objective: To characterize how parkinsonism alters directed connectivity across the motor cortex (M1), subthalamic nucleus (STN), and internal segment of the globus pallidus (GPi). Background:…

    Deep brain stimulation-guided optogenetic rescue of parkinsonian symptoms

    B. Degos, M. Vandecasteele, S. Valverde, C. Piette, G. Gangarossa, W. Derousseaux, A. Aristieta Arbelaiz, J. Touboul, L. Venance (Paris, France)

    Objective: Using opto-activation of cortical interneurons, we aimed at mimicking the cortical effects of deep brain stimulation of the subthalamic nucleus (STN-DBS) to reproduce its…

    Ponto-cortical aberrations:Neural correlations for Hypomimia in PD

    P. Singru, V. Vadiyala, E. Ganesh, V. Vinodhanand (Georgetown, Guyana)

    Objective: We team neuron, focused on analyzing progressive degeneration of neural structural connectivity of the tract from Brodmann area 4, part precentral gyrus to facial motor…

    Neurophysiological correlates of bradykinesia in Parkinson’s disease

    M. Bologna, A. Guerra, G. Paparella, L. Giordo, D. Alunni Fegatelli, AR. Vestri, J. Rothwell, A. Berardelli (Rome, Italy)

    Objective: In the present study we aimed to investigate whether objective measures of bradykinesia in Parkinson’s disease have any relationship with neurophysiological measures in primary…
