  • 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.

  • intrinsic
  • Thus, human neocorticogenesis involves intrinsic programs that enable the emergence of complex neocortical features. (pnas.org)
  • neuroscientists
  • DESPITE MORE THAN A CENTURY OF STUDY, neuroscientists lack a fundamental understanding of how the brain gives rise to the complex thoughts, emotions and behaviors that make us human. (kavlifoundation.org)
  • Cognitive neuroscientists study the human consciousness, specifically the brain, and how it can be seen through a lens of biological and chemical processes. (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)
  • All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards. (springer.com)
  • Functional imaging studies have been performed mainly using human subjects. (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)
  • study
  • Our study suggests an unexpectedly wide range of self-organizing events that are driven by internal programs in human neocortex development. (pnas.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)
  • Several
  • 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)
  • context
  • Multitasking can result in time wasted due to human context switching and apparently causing more errors due to insufficient attention . (wikipedia.org)
  • complex
  • Using 3D culture of human ES cells, we show new self-organizing aspects of human corticogenesis: spontaneous development of intracortical polarity, curving morphology, and complex zone separations. (pnas.org)
  • Workbench Command is a set of command-line tools that can be used to perform simple and complex operations within Connectome Workbench. (humanconnectome.org)
