6 lip 2019 · The visual process is initiated by the detection of a light signal by photoreceptor cells in the outer retina. Photoreceptor cells convert light energy to an electric stimulus, which is then transmitted to the bipolar cells and onwards to the ganglion cells in the retina (see Ch. 1 , p. 46 ).
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.
18 lis 2006 · One brain - two visual systems. Mel Goodale and David Milner, winners of the Society’s Book Award, outline their research. 18 November 2006. Why would anyone think we have two visual systems? After all, we have only one pair of eyes – and clearly we have only one indivisible visual experience of the world.
19 sty 2012 · This chapter reviews the anatomy of the visual system. There are parallel pathways, starting in the retina, then going through the lateral geniculate nucleus, primary visual cortex (V1), secondary visual cortex (V2), then to areas specialized for color and form (V4), and motion and depth (V5).
Describe the basic anatomy of the visual system. Discuss how rods and cones contribute to different aspects of vision. Describe how monocular and binocular cues are used in the perception of depth. The visual system constructs a mental representation of the world around us (Figure SAP.12).
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 human visual system analyzes the interactions between visible electromagnetic waves and the objects in our environment, extracts information about the world from them, and makes visual perception possible.
