A Vertical Asymmetry in Saccades

Journal of Eye Movement Research, 2015
Visual exploration of natural scenes imposes demands that differ between the upper and the lower visual hemifield. Yet little is known about how ocular motor performance is affected by the location of visual stimuli or the direction of a behavioural ...

Cortical potentials with antisaccades

, 1996
The term antisaccade refers to saccades that are performed towards the side opposite to that of target appearance. The performance of antisaccades is considered to be determined by intact frontal inhibitory areas as patients with frontal, and especially ...

Antisaccades and memory-guided saccades in genetic generalized epilepsy and temporal lobe epilepsy

, 2021
Objective: Oculomotor tasks can be used to measure volitional control of behavior sensitive to frontal dysfunction. This study aimed to examine the saccadic eye movement in Genetic Generalized Epilepsy (GGE) which could correlate with the abnormality of ...

Human fronto-tectal and fronto-striatal-tectal pathways activate differently during anti-saccades

Frontiers in Human Neuroscience, 2010
Almost all cortical areas in the vertebrate brain take part in recurrent connections through the subcortical basal ganglia (BG) nuclei, through parallel inhibitory and excitatory loops. It has been suggested that these circuits can modulate our reactions

Differential Contributions of Thalamic Nuclei in the Generation of Antisaccades

, 2010
Our knowledge of thalamus function comes largely from anatomical studies showing, for example, that the ventroanterior (VA) and ventrolateral (VL) nuclei are connected to “motor” regions, whereas the mediodorsal (MD) nucleus is connected to prefrontal ...

Where left becomes right: a magnetoencephalographic study of sensorimotor transformation for antisaccades. [PDF]

, 2007
To perform a saccadic response to a visual stimulus, a 'sensorimotor transformation' is required (i.e., transforming stimulus location into a motor command). Where in the brain is this accomplished?

Functional organisation of saccades and antisaccades in the frontal lobe in humans: a study with echo planar functional magnetic resonance imaging.

, 1998
The cortical activation pattern of saccades and antisaccades (versus rest) in the frontal lobe was analysed using an echo planar imaging (EPI) technique in 10 healthy subjects.

Enhanced modulation of neuronal activity during antisaccades in the primate globus pallidus. [PDF]

, 2009
The antisaccade task has been widely used to investigate the neural mechanisms underlying volitional movement control. In this task, subjects suppress reflexive saccades to the sudden appearance of peripheral visual stimuli (prosaccades) and generate a ...
