Abstract How do the multiple cortico‐basal ganglia‐thalamo‐cortical loops interact? Are they parallel and fully independent, controlled by an arbitrator or are they hierarchically organized? We introduce here a set of four key concepts, integrated and evaluated by means of a neuro‐computational model, that bring together current ideas regarding cortex ‐ basal ganglia interactions in the context of habit learning. According to key concept one, each loop learns to select an intermediate objective...

Abstract Lateralized differences in pallidal outflow are putatively linked to asymmetric tonic contractions of the neck muscles in cervical dystonia (CD). At the population level, the interhemispheric asymmetry has been traditionally studied for the estimation of the spectral power in specified frequency bands. Broadband spectral features, however, were not taken into consideration. The contemporary analysis revealed that the aperiodic (1/f) broadband activity could be a neurophysiological marker...

Abstract The ability to learn, store, and recapture information about unique personal experiences is referred to as episodic memory and is sustained by a network of brain areas that are nestled within the medial temporal lobe (MTL) and associated networks. Human and animal data demonstrate that these structural components are influential in the organization and processing of incoming information. Strengthening the cellular and neural communication within the aforementioned components of the brain,...

Abstract Complete arch fixed implant supported prosthesis made of monolithic zirconia is a popular treatment option with minimal complications, as documented in the literature over a five‐year period. One of the limitations of this material is its inability to be used when the span between adjacent implants is excessively long. A potential solution to mitigate this is problem is to support the zirconia prosthesis with a metal substructure, which intrinsically has higher tensile strength. This clinical...

Abstract Purpose Image registration of the optical intraoral scan to computed tomography image is essential for computer‐guided implant surgery. The remaining teeth, which are considered to be congruent structures observed in the scan and radiographic images, are used to perform the image registration. The purpose of this study was to evaluate the effects of the distribution of matching fiducial points on the accuracy of the image registration. Materials and Methods A partially edentulous...
