![]() It is obviously important for the senses to interact in order to maximize how efficiently people interact with the environment. However, considerations of how unified conscious representations are formed are not the full focus of multisensory Integration research. It can be said therefore, that the binding problem is central to multisensory perception. It was investigated initially in the visual domain (colour, motion, depth, and form), then in the auditory domain, and recently in the multisensory areas. The binding problem stemmed from unanswered questions about how mammals (particularly higher primates) generate a unified, coherent perception of their surroundings from the cacophony of electromagnetic waves, chemical interactions, and pressure fluctuations that forms the physical basis of the world around us. The relationship between the binding problem and multisensory perception can be thought of as a question – the binding problem, and potential solution – multisensory perception. However, recently multisensory effects have been shown to occur in primary sensory areas as well. These areas have extensive connections to each other as well as to higher association areas that further process the stimuli and are believed to integrate sensory input from various modalities. These areas mostly deal with low-level stimulus features such as brightness, orientation, intensity, etc. For example, primary visual area, V1, or primary somatosensory area, S1. The neocortex in the mammalian brain has parcellations that primarily process sensory input from one modality. There are four attributes of stimulus: modality, intensity, location, and duration. Multimodal perception has been widely studied in cognitive science, behavioral science, and neuroscience. The nervous system is thus responsible for whether to integrate or segregate certain groups of temporally coincident sensory signals based on the degree of spatial and structural congruence of those stimulations. Surrounded by multiple objects and receiving multiple sensory stimulations, the brain is faced with the decision of how to categorize the stimuli resulting from different objects or events in the physical world. Multimodal perception is how animals form coherent, valid, and robust perception by processing sensory stimuli from various modalities. 5.2 Psychophysical development of integration.5 Development of multisensory operations.4.4 Dual "what" and "where" multisensory routes.3.1 Perceptual and behavioral consequences.2.3.3 Independence of likelihoods and priors.1.4 Example of spatial and structural congruence. ![]()
