Frequency. ~2% (children) [ 3] Strabismus is a vision disorder in which the eyes do not properly align with each other when looking at an object. [ 2] The eye that is pointed at an object can alternate. [ 3] The condition may be present occasionally or constantly. [ 3] If present during a large part of childhood, it may result in amblyopia, or ...
Stereopsis. Stereopsis (from Ancient Greek στερεός ( stereós) 'solid' and ὄψις (ópsis) 'appearance, sight') is the component of depth perception retrieved through binocular vision. [ 1] Stereopsis is not the only contributor to depth perception, but it is a major one. Binocular vision happens because each eye receives a different ...
Friston makes the following claims about the explanatory power of the theory: "This model of brain function can explain a wide range of anatomical and physiological aspects of brain systems; for example, the hierarchical deployment of cortical areas, recurrent architectures using forward and backward connections and functional asymmetries in ...
A 2-D model of cortical sensory homunculus. A cortical homunculus (from Latin homunculus 'little man, miniature human' [1] [2]) is a distorted representation of the human body, based on a neurological "map" of the areas and proportions of the human brain dedicated to processing motor functions, and/ or sensory functions, for different parts of the body.
A cognitive map is a spatial representation of the outside world that is kept within the mind, until an actual manifestation (usually, a drawing) of this perceived knowledge is generated, a mental map. Cognitive mapping is the implicit, mental mapping the explicit part of the same process.
The lateralization of brain function (or hemispheric dominance[ 1][ 2] / latralisation [ 3][ 4]) is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other. The median longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum.
Sensory maps and brain development is a concept in neuroethology that links the development of the brain over an animal’s lifetime with the fact that there is spatial organization and pattern to an animal’s sensory processing. Sensory maps are the representations of sense organs as organized maps in the brain, and it is the fundamental ...
The first is the theory of modularity. Stemming from phrenology, this theory supports functional specialization, suggesting the brain has different modules that are domain specific in function. The second theory, distributive processing, proposes that the brain is more interactive and its regions are functionally interconnected rather than ...
