It is important that the information of these different sensory modalities must be relatable. The sensory inputs themselves are in different electrical signals, and in different contexts. [6] Through sensory processing, the brain can relate all sensory inputs into a coherent percept, upon which our interaction with the environment is ultimately ...
During sensory immaturity, the more simple and robust information source could be used to tweak the accuracy of the alternate source. [99] Follow-up work by Gori et al. (2012) showed that, at all ages, vision-size perceptions are near perfect when viewing objects within the haptic workspace (i.e. at arm's reach). [ 108 ]
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 ...
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.

Data level fusion algorithms usually aim to combine multiple homogeneous sources of sensory data to achieve more accurate and synthetic readings. [29] When portable devices are employed data compression represent an important factor, since collecting raw information from multiple sources generates huge information spaces that could define an ...
Some people have an abnormally high or low absolute threshold for one or more senses that interferes with their quality of life. They tend to avoid stimulation, seek after it, or perhaps not notice it at all. This can be diagnosed as a sensory processing disorder, also known as sensory integration dysfunction, which is common in people with autism.
In the popular essay "Brain Time", David Eagleman explains that different types of sensory information (auditory, tactile, visual, etc.) are processed at different speeds by different neural architectures. The brain must learn how to overcome these speed disparities if it is to create a temporally unified representation of the external world:
The efficient coding hypothesis was proposed by Horace Barlow in 1961 as a theoretical model of sensory coding in the brain. [1] Within the brain, neurons communicate with one another by sending electrical impulses referred to as action potentials or spikes.
