  2. Motion perception - Wikipedia

    en.wikipedia.org/wiki/Motion_perception

    The inability to perceive motion is called akinetopsia and it may be caused by a lesion to cortical area V5 in the extrastriate cortex. Neuropsychological studies of a patient who could not see motion, seeing the world in a series of static "frames" instead, suggested that visual area V5 in humans [1] is homologous to motion processing area V5/MT in primates.

  3. Biological motion perception - Wikipedia

    en.wikipedia.org/wiki/Biological_motion_perception

    The following model contains detectors modeled from existing neurons that extracts motion features with increasing complexity. (Figure 4). [22] Detectors of Local Motion. These detectors detect different motion directions and are modeled from neurons in monkey V1/2 and area MT [24] The output of the local motion detectors are the following:

  4. Feature detection (nervous system) - Wikipedia

    en.wikipedia.org/wiki/Feature_detection_(nervous...

    Feature detection is a process by which the nervous system sorts or filters complex natural stimuli in order to extract behaviorally relevant cues that have a high probability of being associated with important objects or organisms in their environment, as opposed to irrelevant background or noise.

  5. Phi phenomenon - Wikipedia

    en.wikipedia.org/wiki/Phi_phenomenon

    The Hassenstein–Reichardt detector model is considered to be the first mathematical model to propose that our visual system estimates motion by detecting a temporal cross-correlation of light intensities from two neighboring points, in short a theoretical neural circuit for how our visual system track motion.

  6. Interocular transfer - Wikipedia

    en.wikipedia.org/wiki/Interocular_transfer

    A prolonged exposure to motion of a stimulus in a particular direction causes a perception of motion in the opposite direction. The middle temporal area (known as MT or V5), is associated with motion aftereffects. [10] Interocular transfer occurs in the relational-motion detectors, which are of the binocular or monocular class. The study ...

  7. Corollary discharge theory - Wikipedia

    en.wikipedia.org/wiki/Corollary_Discharge_Theory

    The corollary discharge theory (CD) of motion perception helps understand how the brain can detect motion through the visual system, even though the body is not moving. . When a signal is sent from the motor cortex of the brain to the eye muscles, a copy of that signal (see efference copy) is sent through the brain as

  8. Motion detector - Wikipedia

    en.wikipedia.org/wiki/Motion_detector

    A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.

  9. Hypercomplex cell - Wikipedia

    en.wikipedia.org/wiki/Hypercomplex_cell

    A hypercomplex cell (currently called an end-stopped cell) is a type of visual processing neuron in the mammalian cerebral cortex.Initially discovered by David Hubel and Torsten Wiesel in 1965, hypercomplex cells are defined by the property of end-stopping, which is a decrease in firing strength with increasingly larger stimuli.
