Allen Brain Atlas: Cell Types Database 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 Brain Atlas: Cell Types is a comprehensive brain cell database containing biological features derived from single cell data from both human and mouse brains. It represents part of a multi-year initiative to create a census of cells in the mammalian brain[1].
The Cell Types Database provides open access to electrophysiological, morphological, and transcriptomic data from individual neurons. This resource enables researchers to explore the diversity of brain cell types and download data for offline analysis[1].
Whole cell patch clamp recordings characterize cell firing properties using various stimulus protocols including:
Cells are filled with biocytin and serially imaged to visualize their morphologies. Both planar images and 3D cell reconstructions are available in SWC format.
RNA sequencing provides transcriptomic profiles for individual cells, with gene expression reported as reads aligned to a reference genome.
Various simulated models including:
Cells come from donated ex vivo brain tissue dissected from temporal or frontal lobes, with laminar sampling guided by neuronal density.
Cells are acquired from selected brain areas using transgenic mouse lines with fluorescent reporters. Covered regions include:
| Method | Description |
|---|---|
| Cell Feature Search | Web interface for browsing electrophysiology and morphology data |
| RNA-Seq Data Page | Browse and download transcriptomic data |
| Allen SDK | Programmatic access using Python, includes sample code and Neurodata Without Borders (NWB) format support |
| Allen API | REST API for programmatic queries |
| Direct Download | Individual experiment pages provide download links for recordings, reconstructions, and model parameters |
The Allen SDK provides code for accessing electrophysiology data in NWB format. Neuronal reconstruction files are available as SWC files. Biophysical models require NEURON simulation software, while GLIF models use a custom Python simulator included in the Allen SDK.
The database classifies cells into multiple categories based on:
The Cell Types Database serves as a valuable resource for neurodegeneration research by providing:
All data in the Cell Types Database undergoes quality control including:
The study of Allen Brain Atlas: Cell Types Database has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
