Cognitive, Motor and Oculomotor Contributions to the Trail Making Test in Progressive Supranuclear Palsy

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Progressive supranuclear palsy (PSP) is a neurodegenerative disorder characterized by motor, oculomotor and cognitive impairments. Yet disentangling cognitive deficits from motor and oculomotor dysfunction remains a diagnostic and methodological challenge.

Cortical control of smooth pursuit eye movements [PDF]

, 2007
In this PhD project, the functions of cortical regions that control smooth pursuit eye movements (SPEM) and visual attention were investigated. Combining behavioural (eye movement) measurements and functional magnetic resonance imaging (fMRI) the ...

Neurotransmitter profile of saccadic omnipause neurons in nucleus raphe interpositus [PDF]

, 1994
Saccadic omnipause neurons (OPNs) are essential for the generation of saccadic eye movements. In primates OPNs are located near the midline within the nucleus raphe interpositus (rip).

Kinematic Features of Voluntary and Involuntary Head Movements in Cervical Dystonia

Movement Disorders, EarlyView.
Abstract Background Cervical dystonia (CD) has a varied motor presentation, combining abnormal postures with complex involuntary head movements. Classification of these motor patterns remains imprecise, relying on descriptive terminology without robust definitions. Objectives To provide a kinematically‐grounded description of the motor phenomenology of

Neural control of saccadic eye movements

Current Opinion in Neurobiology, 1993
Recent experiments report that localization of brief targets presented during an ongoing saccade is not accurate. Because interpretations of these findings challenge an important tenet of existing oculomotor models, we examine the methodological and logical bases of these conclusions.

Early Longitudinal Brain Network Changes in Huntington's Disease Before Clinical Motor Onset

Movement Disorders, EarlyView.
Abstract Background Longitudinal studies of seed‐based functional connectivity (SBFC) in young adult Huntington's disease gene‐expanded (HDGE) individuals are rare, and none, to our knowledge, have examined adult cohorts decades from predicted clinical motor diagnosis.

Unveiling Otolith Mystery: Contemporary Testing Approaches and Their Clinical Significance

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Otolith is a critical component of the peripheral vestibular system responsible for detecting linear acceleration. Dysfunction of the otolith organs can lead to vertigo, balance disturbances, and gaze instability. By elucidating the physiological foundations and evaluating both current and emerging methods for assessing otolith ...

FPGA‐Based Real‐Time Implementation of Closed‐Loop Brain‐Controlled Eye Movement System

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper presents a comprehensive closed‐loop brain‐eye movement framework, spanning parametric modelling, dynamic analysis and real‐time FPGA implementation. A simplified first‐order oculomotor model was derived from the classical Robinson formulation to preserve the essential neural‐mechanical feedback structure while enabling efficient ...

Fixational eye movement waveforms in amblyopia: Characteristics of fast and slow eye movements

Journal of Eye Movement Research, 2019
Fixational eye movements comprise of fast microsaccades alternating with slow inter-saccadic drifts. These physiologic eye movements play an important role in visual perception.
