The somatosensory system is a complex sensory system made up of a number of different receptors, including thermoreceptors, nociceptors, mechanoreceptors and chemoreceptors. It also comprises essential processing centres, or sensory modalities, such as proprioception, touch, temperature, and nociception. The sensory receptors cover the skin and ...
Sensory processing is the process that organizes and distinguishes sensation (sensory information) from one's own body and the environment, ...
If there is a unilateral lesion to area V4, a loss of color perception in only half of the visual field may result known as hemiachromatopsia. [3] Similar, but distinct, is color agnosia, which involves having difficulty recognizing colors, while still being able to perceive them as measured by a color matching or categorizing task. [12]
A sensory system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory receptors, neural pathways, and parts of the brain involved in sensory perception. Commonly recognized sensory systems are those for vision, hearing, somatic sensation (touch), taste and olfaction (smell), as ...
Salience (also called saliency, from Latin saliō meaning “leap, spring” [1]) is the property by which some thing stands out.Salient events are an attentional mechanism by which organisms learn and survive; those organisms can focus their limited perceptual and cognitive resources on the pertinent (that is, salient) subset of the sensory data available to them.
In contrast, associative agnosia is a type of agnosia where perception occurs but recognition still does not occur. [1] When referring to apperceptive agnosia, visual and object agnosia are most commonly discussed; this occurs because apperceptive agnosia is most likely to present visual impairments. [ 2 ]
Agnosias are sensory modality specific, usually classified as visual, auditory, or tactile. [2] [3] Associative visual agnosia refers to a subtype of visual agnosia, which was labeled by Lissauer (1890), as an inability to connect the visual percept (mental representation of something being perceived through the senses) with its related semantic information stored in memory, such as, its name ...
Sensory processing disorder (SPD), formerly known as sensory integration dysfunction, is a condition in which multisensory input is not adequately processed in order ...
