Saccadic Body Turns in walking Drosophila
Frontiers in Behavioral Neuroscience, 2014 Drosophila melanogaster structures its optic flow during flight by interspersing translational movements with abrupt body rotations. Whether these ‘body saccades’ are accompanied by steering movements of the head is a matter of debate. By tracking single

A Relative Position Code for Saccades in Dorsal Premotor Cortex [PDF]
, 2010 Spatial computations underlying the coordination of the hand and eye present formidable geometric challenges. One way for the nervous system to simplify these computations is to directly encode the relative position of the hand and the center of gaze ...

Spatial frequency processing in the central and peripheral visual field during scene viewing
, 2016 Visuospatial attention and gaze control depend on the interaction of foveal and peripheral processing. The foveal and peripheral regions of the visual field are differentially sensitive to parts of the spatial-frequency spectrum.

Microsaccades Tracking by Secondary Speckle Pattern Analysis
Journal of Biophotonics, EarlyView.A new approach for detecting microsaccades is introduced using secondary speckle patterns reflected from the sclera. This method offers potential benefits in capturing subtle eye movements and overcoming limitations in traditional pupil‐tracking systems.

Saccadic Behavior during the Response to Pure Vergence Stimuli I: General Properties
Journal of Eye Movement Research, 2007 If two targets are carefully aligned so that they fall along the cyclopean axis, the required eye movement will be symmetrical with the two eyes turning equally inward or outward. When such “pure vergence stimuli” are used only a “pure vergence movement”

Countermanding saccades in humans
Vision Research, 1999 We used a countermanding paradigm to investigate the relationship between conflicting cues for controlling human saccades. Subjects made a saccade to a target appearing suddenly in the periphery; but on some trials, after a delay, a stop-signal was presented that instructed subjects to inhibit the saccade.

Downconversion Master Slave OCT With a Bidirectional Sweeping Laser
Journal of Biophotonics, EarlyView.ABSTRACT This paper explores the challenges of signal processing when using optical coherence tomography (OCT) imaging instruments driven by asymmetric MHz bidirectional sweeping lasers. A downconversion master–slave (DMS) method is proposed as a viable alternative to the traditional OCT protocol.

The influence of visual landscape on the free flight behavior of the fruit fly Drosophila melanogaster [PDF]
, 2002 To study the visual cues that control steering behavior in the fruit fly Drosophila melanogaster, we reconstructed three-dimensional trajectories from images taken by stereo infrared video cameras during free flight within structured visual landscapes ...

Looking away from faces: influence of high-level visual processes on saccade programming
, 2010 Human faces capture attention more than other visual stimuli. Here we investigated whether such face-specific biases rely on automatic (involuntary) or voluntary orienting responses.
