A practical guide to sequencing in neuropsychiatric research

Area of Science:

• Genomics and Computational Biology
• Neuroscience and Psychiatry Research

Background:

• Genome-wide RNA and DNA profiling technologies have rapidly advanced over the past two decades.
• These 'omics' sequencing approaches provide insights into molecular mediators of development and disease.
• Single-cell/nucleus and spatial 'omics' offer unprecedented resolution of cellular processes in complex tissues.

Purpose of the Study:

• To provide a primer on available sequencing technologies for neuroscience and psychiatry.
• To discuss the pros, cons, and optimal applications of different sequencing methods.
• To guide researchers in selecting appropriate techniques for neuropsychiatric research challenges.

Main Methods:

• Review of current genome-wide, single-cell/nucleus, and spatial 'omics' sequencing technologies.
• Comparative analysis of the strengths and limitations of various sequencing approaches.
• Discussion of applications in the context of brain cellular heterogeneity and psychiatric disorders.

Main Results:

• Sequencing technologies provide unbiased insights into molecular mechanisms.
• Single-cell and spatial 'omics' enhance understanding of complex brain tissues.
• Different sequencing techniques are suited for distinct research questions and budgets.

Conclusions:

• The choice of sequencing technology depends on the specific research question in neuroscience and psychiatry.
• Advanced techniques like single-cell and spatial 'omics' are valuable for studying brain heterogeneity.
• A careful consideration of technology capabilities and costs is essential for effective research design.
