For example, PowerPoint now has an easy-to-use animation facility that, in the right hands, can produce very effective educational animations. Because animations can explicitly depict changes over time ( temporal changes), they seem ideally suited to the teaching of processes and procedures.
The MT pathway is involved in the smooth tracking of objects and travels between the SC pathway and the primary visual cortex. In conjunction with the SC pathway and the MT pathway, the FEF pathway allows the infant to control eye movements as well as visual attention. It also plays a part in sensory processing in the infant.
There is a traditional view that visual processing follows a feedforward system where there is a one-way process by which light is sent from the retina to higher cortical areas, however, there is increasing evidence that visual pathways operate bidirectionally, with both feedforward and feedback mechanisms in place that transmit information to ...
With these types of agnosias there is damage to the ventral (what) stream of the visual processing pathway. Object orientation agnosia is the inability to extract the orientation of an object despite adequate object recognition. [34] With this type of agnosia there is damage to the dorsal (where) stream of the visual processing pathway.
For example, it has been shown that visual data can be compressed up to 20 fold without noticeable information loss. [5] Evidence suggests that our visual processing system engages in bottom-up selection. For example, inattentional blindness suggests that there must be data deletion early on in the visual pathway.

The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
As visual information exits the occipital lobe, and as sound leaves the phonological network, it follows two main pathways, or "streams". The ventral stream (also known as the "what pathway") leads to the temporal lobe, which is involved with object and visual identification and recognition .
The dorsal stream (green) and ventral stream (purple) are both actively involved in visual memory. Both pathways originate in the visual cortex. There is a visual cortex in each hemisphere of the brain, much of which is located in the Occipital lobe. The left hemisphere visual cortex receives signals mainly from the right visual field and the ...
