Midline frontal cortex low-frequency activity drives subthalamic nucleus oscillations during conflict.
Making the right decision from conflicting information takes time. Recent computational, electrophysiological, and clinical studies have implicated two brain areas as being crucial in assuring sufficient time is taken for decision-making under conditions of conflict: the medial prefrontal cortex and the subthalamic nucleus (STN). Both structures exhibit an elevation of activity at low frequenci...
متن کاملHuman subthalamic nucleus activity during non-motor decision making
Recent studies have implicated the subthalamic nucleus (STN) in decisions that involve inhibiting movements. Many of the decisions that we make in our daily lives, however, do not involve any motor actions. We studied non-motor decision making by recording intraoperative STN and prefrontal cortex (PFC) electrophysiology as participants perform a novel task that required them to decide whether t...
متن کاملTransient and state modulation of beta power in human subthalamic nucleus during speech production and finger movement.
Signs of Parkinson's disease (PD) are augmented by speech and repetitive motor tasks. The neurophysiological basis for this phenomenon is unknown, but may involve augmentation of β (13-30 Hz) oscillations within the subthalamic nucleus (STN). We hypothesized that speech and motor tasks increase β power in STN and propose a mechanism for clinical observations of worsening motor state during such...
متن کاملSensorimotor adaptation in speech production.
Human subjects are known to adapt their motor behavior to a shift of the visual field brought about by wearing prism glasses over their eyes. The analog of this phenomenon was studied in the speech domain. By use of a device that can feed back transformed speech signals in real time, subjects were exposed to phonetically sensible, online perturbations of their own speech patterns. It was found ...
متن کاملMotor cortex activity predicts response alternation during sensorimotor decisions
Our actions are constantly guided by decisions based on sensory information. The motor cortex is traditionally viewed as the final output stage in this process, merely executing motor responses based on these decisions. However, it is not clear if, beyond this role, the motor cortex itself impacts response selection. Here, we report activity fluctuations over motor cortex measured using MEG, wh...
