Visual processing is a term that refers to the brain's ability to use and interpret visual information from the world. The process of converting light energy into a meaningful image is a complex process that is facilitated by numerous brain structures and higher level cognitive processes.
23 sty 2023 · The ventral stream is the “what” pathway, and helps in the identification of objects that we see. Object identification is a key function of our visual system. The ventral visual stream is responsible for this process. Further, ventral stream structures are important for visual memory.
In this chapter you will learn about how the visual system initiates the processing of external stimuli. The chapter will familiarize you with measures of visual sensation by discussing the basis of form perception, visual acuity, visual field representation, binocular fusion, and depth perception.
6.1.1 Describe the region of the electromagnetic spectrum that is perceived by our visual system, and the relative energy of photons at long and short wavelengths. 6.1.2 Describe the major parts of the eye and their role in focusing light to create a clear image. In this section, we will meet the range of the electromagnetic energy spectrum ...
Visual system - Wikipedia. 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.
The visual system is complex and consists of several interacting anatomical structures. Here, we will describe the process of how photons of light from our surroundings become signals that the brain turns into representations of our surroundings.
The visual system is probably the most-used and most important of the human sensory systems. Some authorities estimate that about 40% of the human CNS is devoted to receiving and processing visual information. The eye is the sensory end-organ responsible for receiving visual information.
