Sensory memory (SM) allows individuals to retain impressions of sensory information after the original stimulus has ceased. [2] A common demonstration of SM is a child's ability to write letters and make circles by twirling a sparkler at night.
Iconic memory is the visual sensory memory register pertaining to the visual domain and a fast-decaying store of visual information. It is a component of the visual memory system which also includes visual short-term memory [1] (VSTM) and long-term memory (LTM).
An example would be a phone number or a sequence of words in a sentence. Despite the quick disappearance of information, short-term memory is an essential step for retaining information in long-term memory stores. Without it, information would not be able to be relayed into long-term memory.
A sensory map is an area of the brain which responds to sensory stimulation, and are spatially organized according to some feature of the sensory stimulation. In some cases the sensory map is simply a topographic representation of a sensory surface such as the skin, cochlea, or retina. In other cases it represents other stimulus properties ...
Most sensory systems have a quiescent state, that is, the state that a sensory system converges to when there is no input. [citation needed] This is well-defined for a linear time-invariant system, whose input space is a vector space, and thus by definition has a point of zero. It is also well-defined for any passive sensory system, that is, a ...
Other sensory modalities exist, for example the vestibular sense (balance and the sense of movement) and proprioception (the sense of knowing one's position in space) Along with Time (The sense of knowing where one is in time or activities). It is important that the information of these different sensory modalities must be relatable.
For example, sensory information from the foot projects to one cortical site and the projections from the hand target in another site. As the result of this somatotopic organization of sensory inputs to the cortex, cortical representation of the body resembles a map (or homunculus).
It suggests a pre-attentive sensory storage system that can hold a large amount of accurate information over a short period of time and consists of an initial phase input of 200-400ms and a secondary phase that transfers the information into a more long term memory store to be integrated into working memory that starts to decay after 10-20s.
