Dissociable roles of dorsolateral prefrontal cortex and frontal eye fields during saccadic eye movements

open access: yesFrontiers in Human Neuroscience, 2015
The dorsolateral prefrontal cortex (DLPFC) and the frontal eye fields (FEF) have both been implicated in the executive control of saccades, yet possible dissociable roles of each region have not been established.

Saccadic suppression of displacement in face of saccade adaptation

open access: yesVision Research, 2011
Saccades challenge visual perception since they induce large shifts of the image on the retina. Nevertheless, we perceive the outer world as being stable. The saccadic system also can rapidly adapt to changes in the environment (saccadic adaptation). In such case, a dissociation is introduced between a driving visual signal (the original saccade target)

The Spectrum of Abnormal Tongue Movements: Review of Phenomenology, Etiology, and Differential Diagnosis

open access: yesMovement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Classifying abnormal tongue movements is challenging due to their varied presentations and limited visibility compared to other body parts. Accurate identification of the phenomenology guides physical examination and can point to specific diagnoses.

Eye Movements in Parkinson’s Disease and Inherited Parkinsonian Syndromes

open access: yesFrontiers in Neurology, 2017
Despite extensive research, the functions of the basal ganglia (BG) in movement control have not been fully understood. Eye movements, particularly saccades, are convenient indicators of BG function.

Ocular-based automatic summarization of documents: is re-reading informative about the importance of a sentence? [PDF]

open access: yes, 2018
Automatic document summarization (ADS) has been introduced as a viable solution for reducing the time and the effort needed to read the ever-increasing textual content that is disseminated.

Collision-avoidance and landing responses are mediated by separate pathways in the fruit fly, Drosophila melanogaster [PDF]

open access: yes, 2002
Flies rely heavily on visual feedback for several aspects of flight control. As a fly approaches an object, the image projected across its retina expands, providing the fly with visual feedback that can be used either to trigger a collision-avoidance ...

Convergence Deficits in Myoclonus‐Dystonia Point to Cerebellar Impairment

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.

Eye tracking disturbances in Schizophrenia

open access: yesIndian Journal of Ophthalmology, 2000
Purpose: To study the frequency of different types of eye tracking disturbances in schizophrenia. Materials and Methods: Smooth pursuit eye movements were studied by electro-oculography (EOG) in 22 schizophrenic patients (ICD-10 criteria) and 15 age and ...

A framework for detection and classification of events in neural activity

open access: yes, 2005
We present a method for the real time prediction of punctate events in neural activity, based on the time-frequency spectrum of the signal, applicable both to continuous processes like local field potentials (LFP) as well as to spike trains.

Searching and fixating: scale-invariance vs. characteristic timescales in attentional processes

open access: yes, 2011
In an experiment involving semantic search, the visual movements of sample populations subjected to visual and aural input were tracked in a taskless paradigm. The probability distributions of saccades and fixations were obtained and analyzed.
