Columnar organization in the motor cortex.
Despite many attempts to find spatial structure in the functional properties of neurons within the primary motor cortex (MI), there is still no compelling evidence for such structure despite the anatomical similarities between motor cortex and other neocortical areas. This is a longstanding puzzle in motor cortical physiology because topographic structure of function is a hallmark of primary se...
متن کاملDesign Principles of Columnar Organization in Visual Cortex
Visual space is represented by cortical cells in an orderly manner. Only little variation in the cell behavior is found with changing depth below the cortical surface, that is, all cells in a column with axis perpendicular to the cortical plane have approximately the same properties (Hubel and Wiesel 1962, 1963, 1968). Therefore, the multiple features of the visual space (e.g., position in visu...
متن کاملCortical Columnar Organization Is Reconsidered in Inferior Temporal Cortex
The object selectivity of nearby cells in inferior temporal (IT) cortex is often different. To elucidate the relationship between columnar organization in IT cortex and the variability among neurons with respect to object selectivity, we used optical imaging technique to locate columnar regions (activity spots) and systematically compared object selectivity of individual neurons within and acro...
متن کاملThe Organization of the Frontal Motor Cortex.
Recent anatomic and functional data radically changed our ideas about the organization of the motor cortex in primates. Contrary to the classic view, the motor cortex does not consist of two main areas, primary and supplementary motor areas, but of a mosaic of cortical areas with specific connections and functional properties.
متن کاملFunctional organization of the motor cortex.
Acknowledgments First of all I would like to thank my advisors, Eilon-for introducing me to the world of research in neuroscience, and Udi-thanks for taking a chance, both on this project and on me personally. Thanks for the guidance and for the encouragement when I was having doubts. Tanya – thanks for your patients and for sharing your tremendous knowledge. Thanks for losing sleep over every ...
