Blind Separation of Spatio-temporal Data Sources
... We do not have prior knowledge of the number of sources, therefore we need to estimate it by using the PCA technique [10] or geometrical version of an ICAtype approach, that permits separation of a larger number of sources than the given number of mixtures [5]. We assume that each neural clique has ...

The extrastriate cortex of the dorsal pathway for spatial localization can process stimuli independently from the sensory modality that conveys the information to the brain and thus appears to be organized ...
