What is a visual brain?
The view is the primary meaning through which we perceive the world around us. This is also the case for most animals on Earth. Although our gaze as humans not by far as powerful as a hawk or spider, a large part of our brains - say the same as half - are somehow involved in seeing. Parts of the brain that help us see objects and tell what they are together are referred to as a visual brain.
Most of the vision takes place at the back of the brain called cerebrum . This area is called a visual brain and consists of two equally important halves: the back of the current and the ventral current. The ventral stream is the lower part of the cortex between the brain and the brain stem and is called the instructional bark in a technical way. In the ventral current, visual data from optical nerves are processed in a way that helps us determine the identity of what it was. For example, when we know the faces of family and friends or distinguish between cat and dog, this perception takes place in the valverral stream.
damage to the ventral stream due to injury or disease leads to the inability of this person to identify what the object is, even if they can clearly see it. This is called visual agnosia and may occur in elderly as part of a degenerative disease such as Alzheimer's disease. In some rare cases, the ventral stream is damaged at a very young age, so the person develops without this visual brain area.
Dorsal current is part of a visual brain that perceives the location of the object. Also known as the parietal cortex, it is located near the upper part of the cortex, above the brain, and is connected to the ventral stream on the back of the brain. When we reach for objectunebo to assess its distance from us, we use the dorsal current.
It also gives us the ability to perceive our field of vision as a whole, the way we look at the map. When anyA part of this visual map moves or changes, the dorsal current processes what this movement means. Damage to this visual brain sector may manifest itself as a number of disorders, all of which are characterized by some types of inability to perceive or interact with objects.
