Allen Cell Types Atlas is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Allen Cell Types Atlas is a landmark resource from the Allen Institute for Brain Science that provides comprehensive, multimodal characterization of cell types in the mammalian brain. This atlas represents a major advance in neuroscience, combining transcriptomics, electrophysiology, and morphology data to create a unified classification of brain cell types that is transforming our understanding of neural circuits in health and disease [1]. [2]
The Cell Types Atlas emerged from the broader BRAIN Initiative and specifically from the BICCN (BRAIN Initiative Cell Census Network) consortium. The project capitalized on advances in single-cell technologies that made it possible to characterize individual cells at unprecedented resolution. [3]
Single-cell RNA sequencing provides molecular fingerprints:
Functional characterization of cell properties:
