In the visual cortex of many mammals, orientation preference changes smoothly along the cortical surface, with the exception of singularities such as pinwheels and fractures. The reason for the existence of these singularities has remained elusive, suggesting that they are developmental artifacts. We show that singularities reduce the length of intracortical neuronal connections for some connec...
Neurophysiological biomarkers were assessed using a transcranial magnetic stimulation multiparadigm approach in 13 presymptomatic (n = 13 Granulin) and 14 symptomatic (n = 11 Granulin, n = 3 C9orf72) subjects with a pathogenic mutation for frontotemporal dementia (FTD). Intracortical facilitation and long-term potentiation-like plasticity were impaired in presymptomatic carriers, compared to he...
Most reports regarding hardware removal involve the violation of the cortex to allow a specialized to tool to extract a retained fragment. This leaves large, unfilled screw holes that act as stress risers for months postoperatively. This article describes a novel technique to remove a retained intracortical screw fragment during total hip arthroplasty. Conversion of an intertrochanteric osteoto...
BACKGROUND AND PURPOSE Using transcranial magnetic stimulation, we investigated short-interval intracortical inhibition and short-latency afferent inhibition in acute ischemic stroke. METHODS We evaluated short-interval intracortical inhibition and short-latency afferent inhibition in the affected hemisphere and unaffected hemisphere in 16 patients and correlated electrophysiological paramete...
1. Department of Radiology, Alysis Zorggroep, location Rijnstate, TA Arnhem, The Netherlands Background: A 42-year-old female presented with chronic knee pain. Anamnesis and physical examination revealed no history of traumatic events. Furthermore, there was no local tenderness, swelling or warm aspect of the knees or tibiae. On conventional imaging, gonarthrosis was seen, as well as a well-def...
