interocular transfer. the transfer of an effect (such as adaptation) from one eye to the other.
What is the visual comparator quizlet?
comparator. An area of the visual system that receives one copy of the order issued by the motor system when the eyes move (the other copy goes to the eye muscles). The comparator can compensate for the image changes caused by the eye movement.
Does interocular transfer occur for motion after effects?
What is it? Interocular transfer is simpler than it sounds. It is just the transfer of an effect (such as moton-after effect) is from one eye to another.
What is the aperture problem quizlet?
The aperture problem is the fact that when a moving object is viewed through an aperture (or a receptive field), the direction of motion of a local feature or part of the object may be ambiguous.
Is a rare neuropsychological disorder in which the affected individual has no perception of motion?
Akinetopsia: A rare neuropsychological disorder in which the affected individual has no perception of motion.
Which part of the optical comparator magnifies the image onto the screen?
The projector magnifies the profile of the specimen, and displays this on the built-in projection screen. On this screen there is typically a grid that can be rotated 360 degrees so the X-Y axis of the screen can be aligned with a straight edge of the machined part to examine or measure.
Which of the following is an important consideration when targeting a shotgun?
Bring your left foot slightly forward (if you’re a right-handed shooter), and lean your body in the same direction. The position of the feet is important. The toes of your forward foot should point at about 45 degrees toward the target. Take the time to place your feet properly, even for a quick shot.
What is interocular transfer?
interocular transfer. Refers to a change in threshold in one eye which had been occluded, similar to, but of lower magnitude, than that in the fixating eye in response to a visual stimulation.
Where does interocular transfer occur?
Interocular transfer is considered to be mediated by binocular units in the visual cortex that are activated by either eye, and the reduced magnitude of IOT relative to monocular aftereffects is attributed to the presence of cortical units that can only be stimulated by one eye.
What is aperture problem?
The aperture problem refers to the fact that the motion of a one-dimensional spatial structure, such as a bar or edge, cannot be determined unambiguously if it is viewed through a small aperture such that the ends of the stimulus are not visible.
What causes the aperture problem?
The local motion information from a single neuron is inherently ambiguous with respect to the global motion. That is, many different motions on the retina could cause the same response in a single motion sensitive neuron with a small receptive field. This is called the aperture problem.
What part of the brain is affected by akinetopsia?
Akinetopsia is thought to be associated with damage to the V5 medial temporal (MT) portion of the brain, involving the tempro-parieto-occipital junction. It is mostly secondary to bilateral disease however has been described in unilateral lesions.
