Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Pharmacology

Background:

  • Optical topography offers a non-invasive approach to assess brain function.
  • Understanding brain responses to environmental factors like alcohol is crucial.
  • Genetic variations, such as ALDH2 genotypes, can influence individual responses to substances.

Purpose of the Study:

  • To evaluate specific brain functions using optical topography.
  • To investigate the impact of alcohol intake on motor cortex hemodynamics.
  • To explore differences in brain response based on ALDH2 genotypes.

Main Methods:

  • Utilized optical topography with twelve optical fibers attached to the head.
  • Measured hemodynamic changes in the motor cortex during a finger-tapping task.
  • Assessed changes before and after alcohol consumption in relation to ALDH2 genotype.

Main Results:

  • Observed distinct hemodynamic changes in the motor cortex among different ALDH2 genotypes.
  • Demonstrated variations in brain activity patterns associated with alcohol intake and genetic factors.

Conclusions:

  • Optical topography is a valuable tool for evaluating specific brain functions.
  • Further research is warranted to explore the relationship between environmental factors and brain function using optical topography.
