that monitoring systems may be implemented within the same cortical network that is responsible for the primary function that has to be monitored. Although much of the functioning of the body_s motor systems occurs without aware-ness, humans are aware that they are moving (or not moving) different parts

Inter-subject alignment of functional MRI (fMRI) data is necessary for group analyses. The standard approach to this problem matches anatomical features of the brain, such as major anatomical landmarks or cortical curvature. Precise alignment of functional cortical topographies, however, cannot

Abstract—We describe a computerized method to automatically find and label the cortical surface in three-dimensional (3-D) magnetic resonance (MR) brain images. The approach we take is to model a prelabeled brain atlas as a physical object and give it elastic properties, allowing it to warp itself

MRI has excellent white/gray matter contrast in the brain due to the presence of myelin, and thus seems uniquely suited for in vivo studies of cortical myeloarchitecture. Here it is demonstrated

this work. Making conclusions about the functional neuroanatomical organiza-tion of the human brain requires methods for relating the functional anatomy of an individual’s brain to population variability. We have developed a method for aligning the functional neuroanatomy of individual brains based

The authors report findings of a large-scale, multitask investigation of sex differences in both structural asymmetries and lateralization of word reading. Two hundred participants were tested in eight divided visual field lexical tasks, and each received a structural magnetic resonance imaging scan. The authors examined whether there was evidence for sex differences in overall measures of neuroanatomical and behavioral lateralization, in specific language tasks and brain regions, and in variation in asymmetry within and across tasks and brain regions. There was very little evidence for sex differences on any behavioral measure. The few indications of sex differences in the current report accounted for 2 % or less of the individual variation in asymmetry and could not be replicated in independent subsamples. No sex differences were observed in the asymmetry of structures in Broca’s and Wernicke’s areas such as pars triangularis, pars opercularis, the planum temporale, planum parietale, or Heschl’s gyrus. There were also no sex differences in the variability of neuroanatomical asymmetries within or between brain regions. However, a significant relationship between planum temporale and behavioral asymmetry was restricted to men.

Abstract: We discuss the relationship between the local-global map hypothesis of Vl and Spiral Harmonic Mosaic algebra, illustrated with a simple model of Vl. We describe long-range patchy connections by assuming they share a symmetry with the local connectivity. We also show that the elongated pattems of connectivity, implicated in the orientation response property, can be related to the patterns of connectivity seen with large injections of tracer. We predict a slight orientation anisotropy in macaque patchy connections. 1.
