Brain stimulation and functional imaging with fMRI and PET.

Area of Science:

• Neuroscience
• Medical Imaging
• Neuromodulation

Background:

• Functional brain imaging techniques like PET, SPECT, and fMRI enable monitoring of neuronal and neurochemical activities in the human brain.
• These techniques aid in identifying abnormal changes associated with neurological and psychiatric diseases.
• Combining imaging with brain stimulation methods like DBS and TMS has significantly advanced the understanding of treatment effects.

Purpose of the Study:

• To summarize recent research combining functional brain imaging and brain stimulation techniques.
• To explore the impact of these combined methods on understanding brain activity and disease networks.
• To discuss future research directions in this interdisciplinary field.

Main Methods:

• Review of studies integrating functional brain imaging (PET, SPECT, fMRI) with brain stimulation techniques (DBS, TMS).
• Analysis of network-level approaches focusing on inter-regional covarying activities.
• Examination of discrepancies arising from technique heterogeneity.

Main Results:

• Combined imaging and stimulation approaches have revealed key mechanisms underlying therapeutic effects of brain stimulation.
• Network-level analysis provides insights into how stimulation impacts disease-related brain networks.
• Reported discrepancies highlight the need for standardization and further methodological development.

Conclusions:

• The integration of functional brain imaging and brain stimulation offers powerful tools for neuroscience research and clinical applications.
• Network-level analysis is crucial for deciphering the complex effects of brain stimulation therapies.
• Future research should focus on addressing methodological heterogeneity to improve reproducibility and advance therapeutic strategies.
