The responses of visual neurons in the frontal eye field are biased for saccades.

2 Nov 2009 Previous research suggests that visually responsive neurons in the frontal eye field (FEF) respond to visual targets even when they are not the goal of a saccadic eye movement. These results raise the possibility that these neurons respond to visual ... Read more...

From neurons to circuits: linear estimation of local field potentials.

2 Nov 2009 Extracellular physiological recordings are typically separated into two frequency bands: local field potentials (LFPs) (a circuit property) and spiking multiunit activity (MUA). Recently, there has been increased interest in LFPs because of their ... Read more...

Diffuse glaucomatous structural and functional damage in the hemifield without significant pattern loss.

30 Oct 2009 OBJECTIVES: To compare the retinal nerve fiber layer (RNFL) thickness and retinal sensitivity in the normal visual hemifield of glaucomatous eyes with localized visual field loss with those of normal eyes and eyes with suspected glaucoma, and to ... Read more...

Technical information about 'Visual Fields'

Definition: The total area or space visible in a person's peripheral vision with the eye looking straightforward. The average extent is about 65 degree upward, 75 degree downward, 60 degree inward, and 95 degree outward. Visual fields can be measured by PERIMETRY.
