From Cells to Selves and Back: Human Neurodiversity at Single-Cell Resolution

Area of Science:

• Neuroscience
• Genomics
• Developmental Biology

Background:

• Human brain development exhibits complex cellular and molecular variations.
• Understanding neurodiversity and neurocomplexity requires high-resolution biological insights.
• The cell has historically been central to biological inquiry.

Purpose of the Study:

• To explore the impact of single-cell omics on understanding human neurodiversity and neurocomplexity.
• To highlight the shift towards single-cell profiling for studying individual genomes and environmental interactions.
• To introduce "in vitro epidemiology" using brain organoids for gene-environment interaction studies.

Main Methods:

• Leveraging single-cell omics technologies for high-resolution analysis.
• Utilizing brain organoids and multiplexing for "in vitro epidemiology".
• Developing computational methodologies for data integration and analysis.

Main Results:

• Single-cell profiling enables unprecedented resolution of individual genomes and environmental interactions.
• Moving beyond categorical cell distinctions reveals the molecular basis of neurodiversity.
• "In vitro epidemiology" allows dissection of gene-environment interactions at single-cell resolution.

Conclusions:

• Single-cell studies and brain organoids are crucial for advancing neurobiology.
• These approaches offer new avenues for cell-based drug discovery and personalized treatments.
• Comprehensive human brain cell atlases are being developed, facing integration challenges.
