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 ...
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 ...
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 ...
The Papez circuit involves various structures of the brain. It begins and ends with the hippocampus (or the hippocampal formation). Fiber dissection indicates that the average size of the circuit is 350 millimeters. The Papez circuit goes through the following neural pathways: Hippocampal formation ( subiculum) → fornix → mammillary bodies ...
Functional integration (neurobiology) Functional integration is the study of how brain regions work together to process information and effect responses. Though functional integration frequently relies on anatomic knowledge of the connections between brain areas, the emphasis is on how large clusters of neurons – numbering in the thousands or ...
Brain mapping is the study of the anatomy and function of the brain and spinal cord through the use of imaging (including intra-operative, microscopic, endoscopic and multi-modality imaging), immunohistochemistry, molecular & optogenetics, stem cell and cellular biology, engineering (material, electrical and biomedical), neurophysiology, and ...
Frontal eye fields. The frontal eye fields ( FEF) are a region located in the frontal cortex, more specifically in Brodmann area 8 or BA8, [ 1] of the primate brain. In humans, it can be more accurately said to lie in a region around the intersection of the middle frontal gyrus with the precentral gyrus, consisting of a frontal and parietal ...
