Other device
☛Eye tracker
An eye tracker is a device mounted for measuring eye positions and eye movement. The eye tracker is added in front of the computer screen, the infrared light source is directed toward the eye and the camera tracks the corneal reflections of light. Advanced algorithms are then used to calculate the position of the eye and determine exactly where it is focused. The eye tracker is applied in a variety of fields such as psychology, medicine, marketing, and engineering.
☛Electroencephalography (EEG)
EEG is a noninvasive monitoring method to record the electrical activity of the brain over time using electrodes placed on the scalp. In order to avoid electrical noise from outside, the experimenter can collect EEG data in an electrically shielded room. After averaging the EEG recording of several trials, the experimenter can observe the brain's response to specific events or stimuli. Because of its high temporal resolution, EEG is widely used in cognitive neuroscience experiments.
☛Response devices
The subjects' responses can be recorded through a fiber optic system which can avoid interference during fMRI scan. Many MRI compatible devices can be used for fMRI data acquisition and our center provides several devices such as 4-Button Inline Fiber Optic Response Pad, Joystick Fiber Optic Response Pad, and Trackball Fiber Optic Response Pad. The experimenters can choose the response device according to the experiment.
☛Metal-free eyeglasses
For those who need to wear glasses during the fMRI experiment, we provide metal-free glasses specifically design for the MRI environment.
