Vision Egg citations


Scene content is predominantly conveyed by high spatial frequencies in scene selective visual cortex

PLoS One
PMCID: 5741213
PMID: 29272283
DOI: 10.1371/journal.pone.0189828

[…] were unfamiliar with the image set and had not participated in the fMRI experiment.Images were shown on a CRT monitor with a refresh rate of 60 Hz, attached to a standard PC running Python using the Vision Egg package []. Participants were seated approximately 57 cm from the screen, and images subtended approximately 23° x 18° of visual angle.In the experiment, participants were asked to categori […]


Complex object motion represented by context‐dependent correlated activity of visual interneurones

PMCID: 5532489
PMID: 28716820
DOI: 10.14814/phy2.13355

[…] The procedure for generation of visual stimuli was similar to that used by (Guest and Gray ). Vision Egg software (Straw ) running on a Python programming platform rendered visual stimuli as 1024 × 1024 pixel portable network graphics (png) files. Individual projected pixels were ~0.7 mm, subt […]


A sublethal dose of a neonicotinoid insecticide disrupts visual processing and collision avoidance behaviour in Locusta migratoria

Sci Rep
PMCID: 5430526
PMID: 28428563
DOI: 10.1038/s41598-017-01039-1

[…] ed on the right side of the wind tunnel, displayed the visual stimulus: the image of a 14 cm black disk, approaching the animal at 300 cm/s on a direct collision course. The stimulus was created with Vision Egg visual stimulus generation software on a Python programming platform. For jumping assays, locusts were oriented 15 cm from and parallel to the rear-projection screen so that the center of t […]


Infants' perception of lightness changes related to cast shadows

PLoS One
PMCID: 5351879
PMID: 28296912
DOI: 10.1371/journal.pone.0173591

[…] ior was videotaped through this camera. The experimenter could observe the infant’s behavior via a monitor connected to the pinhole camera.The experiment was programmed in Python 2.5, with the use of Vision Egg 2.3. Stimuli were constructed off-line before the experiment using 3D rendering software (New Tec LightWave 11.0) and the computer graphic software (Adobe Photoshop CS 6). […]


Transient Dysregulation of Dopamine Signaling in a Developing Drosophila Arousal Circuit Permanently Impairs Behavioral Responsiveness in Adults

PMCID: 5304146
PMID: 28243212
DOI: 10.3389/fpsyt.2017.00022

[…] y a water moat. The arena was uniformly lit with blue light at a luminance intensity of 770 lx from six surrounding LED panels (128 × 32 individual LED units each, Unity Opto Technology Co., Taiwan). Vision Egg software () was used to create the visual stimuli in Python programming language. Visual stimuli were controlled on LEDs with LED Studio Software (Shenzen Sinorad, Medical Electronics, Shen […]


Background visual motion affects responses of an insect motion‐sensitive neuron to objects deviating from a collision course

PMCID: 4886169
PMID: 27207786
DOI: 10.14814/phy2.12801

[…] Visual stimuli were generated using Vision Egg visual stimulus generation software (Straw ). Approach parameters of a looming object can be described by a ratio of the half size of the object (l) divided by the absolute velocity during […]
