Brain Imaging

824
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...

Area of Science:

  • Neuroscience
  • Ethics
  • Cognitive Science

Background:

  • Biomedical enhancement aims to improve human capacities beyond typical levels.
  • Enhancement can target physical, cognitive, or behavioral traits, including morality.
  • The complexity of moral behavior suggests it arises from multiple interacting brain networks.

Purpose of the Study:

  • To test the hypothesis that moral behavior results from multiple, interacting cognitive-affective brain networks.
  • To review evidence on modulating moral behavior using non-invasive brain stimulation.
  • To discuss the ethical implications of moral enhancement.

Main Methods:

  • Review of existing scientific literature on non-invasive brain stimulation and moral behavior.
  • Analysis of cognitive-affective network interactions in moral decision-making.
  • Ethical analysis of potential consequences of moral enhancement.

Main Results:

  • Evidence suggests non-invasive brain stimulation can modulate moral behavior.
  • Moral behavior is likely a product of complex, interacting neural networks, not a single capacity.
  • Altering moral behavior via brain stimulation may not universally improve ethical conduct.

Conclusions:

  • Moral behavior is complex and influenced by multiple interacting neural networks.
  • Non-invasive brain stimulation has the potential to alter moral behavior.
  • Moral enhancement through brain stimulation may yield unpredictable or undesirable outcomes in certain contexts.
