Object processing, including tasks such as object recognition and location, is an example of higher-level visual processing. High-level visual processing depends on both top-down and bottom-up processes. Bottom-up processing refers to the visual system's ability to use the incoming visual information, flowing in a unidirectional path from the ...
Visual stimuli are recorded directly onto the retina, and there are few, if any, external distortions that provide incorrect information to the brain about the true location of an object. [18] Other spatial information is not as reliable as visual spatial information. For example, consider auditory spatial input.
Visual stimuli have been known to process through the brain via two streams: the dorsal stream and the ventral stream. The dorsal pathway is commonly referred to as the ‘where’ system; this allows the processing of location, distance, position, and motion. This pathway spreads from the primary visual cortex dorsally to the parietal lobe.
Examples of mechanoreceptors include baroreceptors which detect changes in blood pressure, Merkel's discs which can detect sustained touch and pressure, and hair cells which detect sound stimuli. Homeostatic imbalances that can serve as internal stimuli include nutrient and ion levels in the blood, oxygen levels, and water levels.
Taste–odor integration occurs at earlier stages of processing. By life experience, factors such as the physiological significance of a given stimulus is perceived. Learning and affective processing are the primary functions of limbic and paralimbic brain. Taste perception is a combination of oral somatosensation and retronasal olfaction. [1]
Visual memory describes the relationship between perceptual processing and the encoding, storage and retrieval of the resulting neural representations. Visual memory occurs over a broad time range spanning from eye movements to years in order to visually navigate to a previously visited location. [1]
The visual cortex is responsible for processing the visual image. It lies at the rear of the brain (highlighted in the image), above the cerebellum. The region that receives information directly from the LGN is called the primary visual cortex (also called V1 and striate cortex). It creates a bottom-up saliency map of the visual field to guide ...
Specificity of processing describes the increased recall value of a stimulus when presented in the method with which it was inputted. For example, auditory stimuli (spoken words and sounds) have the highest recall value when spoken, and visual stimuli have the highest recall value when a subject is presented with images. [6]
