  • fMRI
  • and apply them to connectomes from fMRI brain scans collected during a serial reaction time task study. (nih.gov)
  • and 3) task based fMRI (tfMRI), which is employed to identify functional parcellation in the human brain in order to assist analyses of data obtained with the first two methods. (nih.gov)
  • These findings underscore the need to consider the effect that a specific parcellation approach has on graph analytic findings in human fMRI studies, and indicate that results obtained using different templates may not be directly comparable. (frontiersin.org)
  • cortical
  • In the human visual system, each eye projects to both hemispheres, while for smell, the major cortical projection from each nostril goes directly to the ipsilateral side. (medicalxpress.com)
  • Topologically efficient and biologically expensive hubs of the brain anatomical network had greater rates of shrinkage/myelination and were associated with overexpression of the same transcriptional profile as cortical consolidation. (bcu.ac.uk)
  • cerebral cortex
  • The length of an axon can be extraordinary: for example, if a pyramidal cell, (an excitatory neuron) of the cerebral cortex were magnified so that its cell body became the size of a human body, its axon, equally magnified, would become a cable a few centimeters in diameter, extending more than a kilometer.

  • macaque
  • Coverage includes the brain and spinal cord of the four species most frequently studied by neuroscientists: human, macaque (monkey), rat and mouse. (wikipedia.org)
  • investigate
  • Using a multi-objective evolutionary approach that approximates a Pareto-optimal set within the morphospace, we investigate the capacity of anatomical brain networks to evolve towards topologies that exhibit optimal information processing features while preserving network cost. (royalsocietypublishing.org)
  • The simplest experimental design used to investigate human multitasking is the so-called psychological refractory period effect. (wikipedia.org)
  • Results demonstrate that overall, these approaches represent a significant advance in MR imaging of the human brain to investigate brain function and structure. (nih.gov)
  • Imaging
  • Bridging the scales and relating anatomical and activity data is the major challenge addressed using electron microscopy, 3D polarized light imaging (3D-PLI), electrophysiological and MRI measurements, in combination with modeling and simulation. (fz-juelich.de)
  • Functional imaging studies have been performed mainly using human subjects. (wikipedia.org)
  • patterns
  • These patterns have been seen in both animals and humans, and are present at only certain points during a scanner session. (wikipedia.org)
  • context
  • Multitasking can result in time wasted due to human context switching and apparently causing more errors due to insufficient attention . (wikipedia.org)
  • Several topics that might be covered here are instead covered there because much more can be said about them in a human context. (wikipedia.org)
  • vertebrates
  • The basal ganglia form a major brain system in all species of vertebrates, but in primates (including humans) there are special features that justify a separate consideration. (wikipedia.org)
  • studies
  • While descriptive studies have identified a number of characteristic topological attributes [ 3 - 5 ], the fundamental selectional forces and factors that have shaped human brain network topology remain poorly understood. (royalsocietypublishing.org)
  • novel
  • Motivated by this previously untapped anatomical knowledge, we develop a novel tractography method that preserves both topographic and geometric regularity of fiber systems. (humanconnectome.org)
  • different
  • A brain atlas is composed of serial sections along different anatomical planes of the healthy or diseased developing or adult animal or human brain where each relevant brain structure is assigned a number of coordinates to define its outline or volume. (wikipedia.org)
  • sets
  • By providing statistical tools that analyze sets of connectomes without loss of information, new insights into neurology and medicine may be achieved. (nih.gov)
