The Subthalamic Nucleus Contributes to Post-error Slowing
pFC is proposed to implement cognitive control via directed "top-down" influence over behavior. But how is this feat achieved? The virtue of such a descriptive model is contingent on a mechanistic understanding of how motor execution is altered in specific circumstances. In this report, we provide evidence that the well-known phenomenon of slowed RTs following mistakes (post-error slowing) is d...
متن کاملPost-error slowing: an orienting account.
It is generally assumed that slowing after errors is a cognitive control effect reflecting more careful response strategies after errors. However, clinical data are not compatible with this explanation. We therefore consider two alternative explanations, one referring to the possibility of a persisting underlying problem and one on the basis of the low frequency of errors (orienting account). T...
متن کاملTesting theories of post-error slowing
People tend to slow down after they make an error. This phenomenon, generally referred to as post-error slowing, has been hypothesized to reflect perceptual distraction, time wasted on irrelevant processes, an a priori bias against the response made in error, increased variability in a priori bias, or an increase in response caution. Although the response caution interpretation has dominated th...
متن کاملStopping and slowing manual and spoken responses: Similar oscillatory signatures recorded from the subthalamic nucleus.
Response control in the forms of stopping and slowing responses is thought to be implemented by a frontal-subcortical network, which includes the subthalamic nucleus (STN). For manual control, stopping is linked to STN beta (13-30 Hz) and slowing responses are linked to lower frequencies (<12 Hz). Whether similar STN oscillatory activities are associated with the control of spoken responses is ...
متن کاملTargeting the subthalamic nucleus.
The small size and surrounding neuronal structures and fibre tracts make the STN a difficult stereotactic target. In this article we present the technique used by us to target the STN. Our combined experience from two centres comprises 18 lesions and 27 stimulator implants in the STN. Our criteria for patient selection and the use of MRI, frame-on CT and volumetric image fusion are presented. T...
