Brain Imaging

902
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...

Magnetic Resonance Imaging

10.3K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Area of Science:

  • Cognitive Neuroscience
  • Information Theory
  • Neuroimaging

Background:

  • Psychology evolved from behaviorism to information processing, inspired by Shannon's quantifiable information theory.
  • Cognitive science advanced to cognitive neuroscience, aiming to measure neural information.
  • The term "information" lacks a precise definition in current cognitive neuroscience.

Purpose of the Study:

  • To re-evaluate cognitive neuroscience findings using Shannon's information theory.
  • To highlight the distinction between experimenter-as-receiver and cortex-as-receiver perspectives.
  • To propose a shift in empirical research focus within cognitive neuroscience.

Main Methods:

  • Analysis of existing cognitive neuroscience literature.
  • Application of Shannon's information formulation to neuroimaging data interpretation.
  • Conceptual framework development for information in the brain.

Main Results:

  • Modern neuroimaging results may be misinterpreted due to an imprecise definition of information.
  • Current research often prioritizes the experimenter's interpretation (experimenter-as-receiver) over the brain's internal processing (cortex-as-receiver).

Conclusions:

  • A rigorous application of Shannon's information theory can refine the interpretation of neuroimaging data.
  • Refocusing on the cortex-as-receiver perspective is crucial for advancing cognitive neuroscience.
  • This conceptual shift necessitates changes in empirical research design and execution.
