Hemodynamic imaging of the auditory cortex

Area of Science:

• Neuroscience
• Auditory Neuroscience
• Neuroimaging

Background:

• Functional magnetic resonance imaging (fMRI) has become a dominant non-invasive technique in human neuroscience over the last two decades.
• It is widely used for measuring perceptual and cognitive processing in the brain.

Purpose of the Study:

• To provide a comprehensive overview of functional magnetic resonance imaging (fMRI) as a method in human auditory neuroscience.
• To explain the practicalities of using fMRI for assessing central auditory coding.
• To highlight key concepts and considerations for auditory fMRI experiments.

Main Methods:

• Review of fundamental Magnetic Resonance (MR) physics underlying fMRI.
• Comparison of auditory fMRI advantages over alternative neuroimaging techniques.
• Discussion of practical aspects of setting up, conducting, and analyzing auditory fMRI experiments.

Main Results:

• fMRI offers a powerful non-invasive approach to study auditory processing and coding in the human brain.
• Understanding MR physics, experimental design, and data analysis is crucial for successful auditory fMRI.
• Specific examples illustrate fMRI's utility in investigating basic sound coding, including frequency and pitch perception.

Conclusions:

• Auditory fMRI is an established and influential method in auditory neuroscience.
• The review equips readers with foundational knowledge for applying fMRI to auditory research.
• Future developments in fMRI technology are expected to further enhance its utility in understanding auditory perception.
