Behavioural Color Discrimination in Monkeys

Check if the same lab product or an alternative is used in the 5 most similar protocols

The behavioural colour discrimination evaluation was performed in a computerized system consisting of a video monitor (Diamond Pro 2070SB, Mitsubishi, Cypress, CA, USA, spatial resolution: 2048 × 1536 at 86 Hz -, frame rate: 160 Hz, colour resolution: 14 bits) in which the stimuli were displayed on a video monitor adapted to receive touch inputs. A software programmed the experimental sessions and recorded the monkey’s responses. The setup (ViSaGe system® - Cambridge Research Systems, Rochester, UK, and CRT monitor), previously used and described in detail by Goulart and collaborators [20 (link)], was adapted for Alouatta subjects, with a larger food dispenser and tray. Gamma correction was performed to calibrate the luminance of the monitor guns using the software VSG Desktop (CRS) and a ColorCAL MKII Colorimeter (Cambridge Research Systems, Rochester, UK). The monitor was placed at a distance of 20 cm from the subjects’ eyes, allowing them to reach the target only with the fingers. For this experiment, the equipment was mounted on a mobile rack, allowing in situ experiments, attached to a 60 × 60 × 60 cm experimental chamber.

Eye Tracking Study of University Students

Subjects were four students of the University of Potsdam (all female, ages 21, 23, 24, and 26 years) who participated in exchange of study credit or a total of 21€ for their participation in three sessions. All participants had normal or corrected-to-normal vision. Subjects sat 60 cm in front of the computer screen (Mitsubishi Diamond Pro 2070 SB) in a dimly lit room with their heads stabilized on a chinrest. Movements of the right eye were recorded. The eye tracker was calibrated with a standard 9-point calibration and validation procedure before the beginning of each block and after every 12th trial.

Visual Stimuli and Eye Tracking Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

For all experiments except Experiment 3b, stimuli were generated by a ViSaGe graphics card (Cambridge Research Systems Ltd., Rochester, UK) and displayed on a 100-Hz CRT screen (Mitsubishi Diamond Pro 2070SB), with a resolution of 1,024 x 768 pixels. Experiments took place in a dimly lit room. Observer’s head was maintained fixed by a chin-forehead rest 67 cm away from the screen. Eye position was recorded by a video-based eye tracker with a sampling frequency of 250 Hz (CRS High Speed Video Eyetracker, Cambridge Research Systems Ltd., Rochester, UK). The eye tracker was calibrated at the beginning of each session by presenting nine points in a pseudo-random order covering the display area.
In Experiment 3b, the PsychToolbox for MATLAB (Brainard, 1997 (link)) was used to display the stimuli and the Eyelink 1000 (SR-Research, Osgoode, Ontario, Canada) was used to track eye movements. The refresh rate of the monitor was 85 Hz instead of 100 Hz.

Precise Calibration of Visual Stimuli

Check if the same lab product or an alternative is used in the 5 most similar protocols

Visual stimuli were generated using Matlab 7.12 (The Math-Works, Natick, MA) with PsychToolbox 3.0 (Brainard, 1997; Pelli, 1997) . They were displayed on a 20-inch CRT monitor (Mitsubishi Diamond Pro 2070sb, 1280 Â 1024 pixel resolution and 100 Hz refresh rate) at a viewing distance of 57 cm. A SpectroCAL (Cambridge Research Systems, Rochester, Kent, UK) photometer was used for the luminance calibration and the linearization of the display. The minimum and maximum luminance values of the screen were .48 and 106.56 cd/m 2 , respectively. The mean luminance was 53.52 cd/m 2 . Precise temporal overlapping of triggers and the onset times of each stimulus during a trial were verified with a digital oscilloscope (Rigol DS 10204B, GmbH, Puchheim, Germany) connected to a photodiode which detected visual stimulus onsets and offsets. All data were collected in a silent and dimly lit room.

Direction Discrimination of Drifting Gabor Patches

Check if the same lab product or an alternative is used in the 5 most similar protocols

The stimulus was a drifting Gabor patch shown along with its parameters in Figure 2. Size and contrast of the stimulus remained constant within a testing block; there were four blocks corresponding to the four combinations of size and contrast level. For each block, there were 6 presentation times (17, 33, 66, 132, 264 and 528 msec), 2 directions (left and right) and 4 repetitions, for a total of 48 trials. The stimulus characteristics are illustrated in Figure 2. The participants’ task was to report the direction of motion of the Gabor patch, left or right, by pressing the appropriate arrow button on a standard computer keyboard. Stimuli were programmed using psychophysics toolbox and MatLab (Brainard, 1997 (link)) and were presented on one of two 21″ CRT monitors. Twenty-two patients and 10 controls were tested on a Mitsubishi Diamond Pro 2070sb, mean luminance 47.3 cd/m², which presented the low-contrast stimulus at 3.4% contrast, and the high contrast stimulus at 75.1% contrast. The remaining 7 patients and 12 controls were tested on one of two Hewlitt Packard FP2141sb, mean luminances of 58.4 and 56.2cd/m²). The maximum contrast values for these two monitors were 4% and 3.8% respectively for the low contrast stimuli, and 81.8% and 79.2% respectively for the high contrast stimuli. All three monitors operated at 120 Hz.

Smooth Pursuit Eye Movement Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

The subjects were seated 70 cm in front of a CRT monitor (22 inch, Diamond Pro 2070SB, Mitsubishi, refresh rate of 100 Hz, background mean luminance 60 cd/m²) with the head stabilized by a chin rest and a forehead restraint. Eye position signals from the right eye were calibrated by requiring the subjects to fixate a target spot (diameter of 0.3 deg) at known horizontal and vertical eccentricities in binocular viewing condition. The visual stimuli and target motion were generated by Psychophysics Toolbox extensions on MATLAB (Mathworks, MA). Smooth pursuit was produced by a step‐ramp paradigm (Rashbass 1961) with a constant speed of 18.5 deg/sec. The pursuit stimuli (diameter of 2 deg) were random dot fields (each dot, 5 × 5 pixels) whose contrast was modulated by a Gaussian window with a space constant of 20 pixels. Dots had a density of 50% and dot lifetime was equal to presentation duration. The subjects first fixated on a central stationary target (diameter of 0.3 deg) that appeared on uniform gray background for 1.0–1.5 sec and a pursuit target appeared 1.4 deg left or right from the center. The target then started to move either leftward or rightward. The subjects were instructed to track a moving target with their eyes. Ten trials were conducted for each direction. The leftward and rightward directions for smooth pursuit were randomized.

Visual Stimuli Presentation and EEG Synchronization

Visual stimuli were generated with Matlab 7.12 (The Math-Works, Natick, MA) and presented by using the PsychToolbox 3.0 (Brainard, 1997; Pelli, 1997) . A 20-inch CRT monitor (Mitsubishi Diamond Pro 2070sb, 1600 Â 1200 pixel resolution and 60 Hz refresh rate) was used to display the stimulus from a viewing distance of 57 cm with a chinrest to stabilize the head. All procedures were carried out in a dark room. A photometer (SpectroCAL, Cambridge Research Systems, Rochester, Kent, UK) was used for the calibration of the display. Using a digital oscilloscope (Rigol DS 10204B, GmbH, Puchheim, Germany) connected to a photodiode centered over the position of our stimuli, we continuously synchronized our EEG recordings with the stimulus/event onset times.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
