Area of Science:

Neuroscience
Genomics
Cell Biology

Background:

Understanding human cortical functions requires detailed knowledge of neural cell organization.
Previous studies lacked comprehensive molecular and spatial data for multiple human cortical regions.

Purpose of the Study:

To create a high-resolution spatial physiological atlas of human cortical neurons.
To characterize neural cell organization, molecular features, and spatial arrangements across 14 cortical regions.

Main Methods:

Subcellular-level spatial transcriptomic sequencing.
Single-nucleus RNA sequencing (snRNA-seq).
Integration with functional brain networks.

Main Results:

Generated a single-cell atlas with transcriptomic data from over 1.1 million nuclei and spatial profiles from over 1.8 million cells.
Identified distinct expression patterns and laminar distributions for glutamatergic and SST neurons.
Revealed regional differences in neuron-glia communication and cell-cell interactions.

Conclusions:

The atlas provides a comprehensive reference for studying neurological diseases and cortical functions.
Detailed spatial organization and molecular characteristics of human cortical cells are now better understood.
Findings offer insights into the cellular basis of complex intelligent functions in the human cortex.
