Area of Science:

  • Neuroscience
  • Motor Control
  • Brain Imaging

Background:

  • Voluntary walking is a complex human motor activity.
  • Understanding the neural basis of locomotion is crucial for neuroscience.
  • Previous research has implicated various brain regions in gait control.

Purpose of the Study:

  • To investigate brain activity changes during voluntary walking in healthy individuals.
  • To identify specific brain regions involved in human bipedal locomotion.
  • To utilize advanced neuroimaging techniques for detailed analysis.

Main Methods:

  • Employed technetium-99m-hexamethyl-propyleneamine oxime (99mTc-HMPAO) single photon emission computed tomography (SPECT).
  • Analyzed brain perfusion changes in 14 healthy adult subjects during voluntary walking.

  • Utilized Statistical Parametric Mapping (SPM) for data analysis.

    • Main Results:

    • Significant brain activation was observed in the supplementary motor area.
    • The medial primary sensorimotor area showed increased activity.
    • Activation was also noted in the striatum, cerebellar vermis, and visual cortex.

    Conclusions:

    • Cerebral cortical areas involved in motor function are critical for walking.
    • The visual cortex plays a role in guiding bipedal movement.
    • Basal ganglia and cerebellum are integral components of the human locomotor network.
