Modulation of Brain Function and Behavior by Focused Ultrasound

Area of Science:

• Neuroscience
• Biophysics
• Medical Technology

Background:

• Focused ultrasound (FUS) has emerged as a significant tool in neuroscience research.
• Its applications are expanding for potential treatments of various brain disorders.

Purpose of the Study:

• To review recent advancements in understanding how FUS affects the central nervous system.
• To explore FUS applications alone and in combination with other agents.

Main Methods:

• Review of recent scientific literature on focused ultrasound applications in the central nervous system.
• Analysis of studies investigating FUS effects on neuronal activity, perception, and behavior.

Main Results:

• Focused ultrasound can directly modulate neuronal activity, influencing perception and behavior.
• Combining FUS with microbubbles to open the blood-brain barrier enhances and sustains neural and behavioral effects.
• Blood-brain barrier opening facilitates targeted drug and gene delivery.

Conclusions:

• Focused ultrasound technology is maturing for altering brain activity, with or without adjuncts.
• Further research is required to fully understand biophysical mechanisms.
• Future efforts will focus on improving targeting specificity, affected tissue volume, cell-type specificity, and effect duration.
