Dissociable Cortical and Subcortical Mechanisms for Mediating the Influences of Visual Cues on Microsaccadic Eye Movements

Frontiers in Neural Circuits, 2021
Visual selection in primates is intricately linked to eye movements, which are generated by a network of cortical and subcortical neural circuits. When visual selection is performed covertly, without foveating eye movements toward the selected targets, a

The Tendon‐to‐Bone Seam: A Transtendinous Approach to Rotator Cuff Repair

Arthroscopy Techniques, EarlyView.
Abstract This technique article describes the tendon‐to‐bone seam technique, a knotless, transtendinous approach to arthroscopic rotator cuff repair. The technique employs a single‐use deployment device preloaded with multiple PEEK anchors interconnected with a single polyethylene #2 suture, enabling the surgeon to create a continuous “seam” of ...

Smooth pursuit and saccadic abnormalities in first-episode schizophrenia. [PDF]

, 1998
Background. Previous studies of oculomotor dysfunction in schizophrenia have tended to concentrate on abnormalities of smooth pursuit eye tracking in chronic medicated patients. We report the results of a study of smooth pursuit, re¯exive and antisaccade

Prescribing competence: The pros and cons of different methods for assessment

British Journal of Clinical Pharmacology, EarlyView.
Evaluating a medical graduate’s competence in rational prescribing is challenging. With the aim to guide and inspire teachers, this narrative review explores different methods that can be used to assess prescribing competence. Each method has its own advantages and disadvantages, and thus a mix of different assessment methods is needed throughout the ...

High-Field fMRI Reveals Brain Activation Patterns Underlying Saccade Execution in the Human Superior Colliculus [PDF]

, 2010
Background: The superior colliculus (SC) has been shown to play a crucial role in the initiation and coordination of eye-and head-movements. The knowledge about the function of this structure is mainly based on single-unit recordings in animals with ...

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

Droplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Deconstructing saccades : identifying the components of saccades that produce saccade-induced retrieval enhancement. [PDF]

, 2013
Multiple studies have found that performing repetitive saccades for 30 s improves subsequent memory retrieval. Although the effect is well established, the mechanism by which saccades affect retrieval is currently unknown.

Paroxysmal slow waves mark ictal networks

Epilepsia, EarlyView.
Abstract Objective Epilepsy diagnosis and treatment monitoring are hindered by the episodic, heterogeneous expression of seizures and by normal‐appearing scalp electroencephalography (EEG) in many patients. We previously described paroxysmal slow‐wave events (PSWEs), brief epochs of broadband slowing detectable on EEG in people with epilepsy.

Dopamine and impairment at the executive level. [PDF]

, 1999
Patients with schizophrenia have an impairment in the inhibition of reflexive saccades, as a consequence of a functional impairment of the prefrontal cortex, which has not yet been encapsulated in terms of a formal model.

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

Epilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.
