Area of Science:

• Neuroscience
• Developmental Biology
• Genetics

Background:

• Zebrafish are widely used in developmental biology and genetics.
• Their vertebrate system complexity and practical simplicity make them ideal for research.
• Increasingly, zebrafish are utilized in neuroscience research due to genetic tools and knowledge.

Purpose of the Study:

• To review behavioral screening methods for assessing brain function in zebrafish.
• To highlight the utility of zebrafish for high-throughput mutation and drug screening.
• To provide examples of behavioral tests for learning, memory, fear, anxiety, and social behavior.

Main Methods:

• Behavioral test paradigms are presented as key methods for identifying alterations in brain function.
• The review focuses on the principles of behavioral screening rather than specific experimental results.
• Examples cover learning and memory, fear and anxiety, and social behavior domains.

Main Results:

• Behavioral screening in zebrafish enables the identification of functional alterations in the vertebrate brain.
• These methods are suitable for high-throughput screening of mutations and drugs.
• The review showcases the rapid evolution of zebrafish behavioral screening.

Conclusions:

• Zebrafish behavioral screening is a valuable approach for neuroscience research.
• The methods discussed are applicable to various functional domains of the brain.
• This review offers a snapshot of the current state of zebrafish behavioral screening techniques.
