VISUAL PATHWAYS Meaning and
Definition
-
Visual pathways refer to the intricate network of neurological connections and structures responsible for transmitting and processing visual information from the eyes to the brain. These pathways enable the perception, interpretation, and recognition of visual stimuli in the environment.
The process of visual perception begins with the capture of light by rods and cones in the retina. From there, visual information travels along two main pathways: the dorsal pathway (also known as the "where" pathway) and the ventral pathway (also known as the "what" pathway).
The dorsal pathway is responsible for processing the spatial and temporal information of visual stimuli. It helps us to determine the location, motion, and depth of objects in the visual field. This pathway connects the primary visual cortex to other areas of the brain involved in motion detection, motor control, and spatial awareness.
On the other hand, the ventral pathway focuses on the identification and recognition of objects. It is involved in object perception, face recognition, and color processing. This pathway connects the primary visual cortex to regions of the brain involved in object recognition, memory, and visual association.
Both pathways are interconnected and work in conjunction to provide a comprehensive understanding of the visual world. The visual pathways play a crucial role in various aspects of human cognition, including perception, attention, memory, and decision-making. Disorders or damage to these pathways can lead to visual impairments, such as color blindness, visual agnosia, or optic neuropathy.

Etymology of VISUAL PATHWAYS
The etymology of the word "Visual Pathways" can be broken down as follows:
1. Visual: The word "visual" is derived from the Latin word "visus" which means sight or vision. It entered the English language in the 15th century and refers to anything related to sight or the sense of vision.
2. Pathway: The word "pathway" comes from the combination of two words: "path" and "way". "Path" can be traced back to the Greek word "pathos" which means suffering, experience, or emotion. "Way" originates from the Old English word "weg" which means a road, passage, or journey. Together, "pathway" refers to a route or passage that leads from one place to another.
