Chapter 5: Sensation and Perception Sensation is the detection of physical stimuli in the environment. Perception is our conscious experience of those stimuli. Describe how sensory information is translated into meaningful stimuli. Transduction is the process by which sensory stimuli are translated into signals the brain can interpret. Transduction occurs at sensory receptors, specialized cells in each sense organ. Sensory receptors send messages to the thalamus, which sends projections to cortical areas for perceptual processing.

- The image captured by each eye is transmitted to the brain by the optic nerve. This nerve terminates on the cells of the lateral geniculate nucleus, the first relay in the brain's visual pathways. The cells of the lateral geniculate nucleus then project to their main target, the primary visual cortex.he projection from the LGN to the visual cortex is called the optic radiation. Because damage at any point along the pathway from the retina to the cortex results in some degree of blindness, this is clearly the pathway through which conscious visual perception takes place in human beings.

How do humans react to visual or sound stimuli? Alternatively you could use a hydrodynamic metaphor: the brain is like a network of rivers, with tributaries, distributaries, channels and canals. Visual or sound stimuli create waves in particular streams and rivulets, and these waves travel through the network, merging with other streams.

- For instance, our eyes receive and convert light waves into electrical energy which are transmitted to the visual cortex of the brain to create the sensation of vision and subsequently leading to perception. But each sense receptor requires a minimum level of energy to excite it before perception can take place.

Penn researchers calculate how much the eye tells the brain The retina is actually a piece of the brain that has grown into the eye and processes neural signals when it detects light. Ganglion cells carry information from the retina to the higher brain centers; other nerve cells within the retina perform the first stages of analysis of the visual world.

- Visual Stimuli. 1  Visual stimuli are the most basic aspect of the experimental protocol, and often the most critical one as the choice of stimuli and of their parameters may define and limit the scope of your experiments. Psykinematix provides convenient tools to specify their spatial, temporal, and chromatic properties.

- Key Points. 1  Sensation is input about the physical world registered by our sensory receptors, such as our eyes, ears, mouth, nose, and skin. 2  Perception is the process by which the brain selects, organizes, and interprets sensations; it is often influenced by learning, memory, emotions, and expectations.

- in vision therapy individuals relearn or enhance the use of different brain or thought processes to alleviate visual discomfort and use visual skills more efficiently this is possible because vision is a learned process and eyes are actually modified brain tissueision training therapy vt is a subspecialty of optometry that strives to improve enhance and or develop visual performance through a prescribed treatment program that is designed to literally build new neural patterns

visual pathway a pathway over which a visual sensation is transmitted from the retina to the brain. A pathway consists of an optic nerve, the fibers of an optic nerve traveling through the optic chiasm to the lateral geniculate body of the thalamus, and optic radiations terminating in an occipital lobe.

Shared Flashcard Set Refers to the process used by the brain to combine (or bind) the results of many sensory operations into a single percept. This occurs, for example, when sensations of color, shape, boundary, and texture are combined to produce the percept of a person's face. No one knows exactly how the brain does this. Thus the binding problem is one of the major unsolved mysteries in psychology.

What is the structure of the Visual Cortex? The Visual cortex is a component of the cerebral cortex that receives and processes the sensory nerve impulses from the eyes. The cerebral cortex is a layer of neural tissue that participates actively in the reminiscence, concentration, consciousness, thinking process and language processes.

- Human vision is one of the most complex visual systems among animals. The main sensory organ of the visual system is the eye, which takes in the physical stimuli of light rays and transduces them into electrical and chemical signals that can be interpreted by the brain to construct physical images.

Visual system The visual system is the part of the central nervous system which gives organisms the ability to process visual detail, as well as enabling the formation of several non-image photo response functions. It detects and interprets information from visible light to build a representation of the surrounding environment.

Visual perception Visual perception. Visual perception is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment. The resulting perception is also known as visual perception, eyesight, sight, or vision (adjectival form: visual, optical, or ocular). The various physiological components involved in vision are referred to collectively as the visual system, and are the focus of much research in linguistics, psychology, cognitive science, neuroscience, and molecular biology, collectively referred to as vision science

The Senses Retina: light sensitive layer of rods and cones converting light into nerve impulses. The retina is the film of the eye. It converts light rays into electrical signals and sends them to the brain through the optic nerve. The sides of the retina are responsible for our peripheral vision.

- The retina is the photo receptive sensory layer of the back of the eye, where the optics of the eye focuses an image of what is in front of the eye. The optic nerve carries signals from the retina to the brain, which interprets them as visual images. The retina has two types of cells the rods and cones.

Visual capture One example of visual capture is known as the ventriloquism effect, which refers to the perception of speech sounds as coming from a direction other than their true direction, due to the influence of visual stimuli from an apparent speaker.
