Allen Cell Types Database updated with new data and models

March 16, 2017

The Allen Institute for Brain Science has released additional data and computer models of cell activity for inclusion in the Allen Cell Types Database: a publicly available tool for researchers to explore and understand the building blocks of the brain.

"Comprehensive coverage of hundreds to thousands of cells will be crucial for scientists who want to explore the diversity of nerve cells in the brain, and provides a base from which we can parse cells into meaningful types," says Lydia Ng, Ph.D., Senior Director of Technology at the Allen Institute for Brain Science. "This release is one more step in building a fundamental framework to help make advancements in neuroscience."

Models serve as a critical link between observed data and theories about how cells work, enabling scientists to understand the mechanisms that give rise to neuron function. Two types of models have been added and updated as part of this release. The first set are models that reduce the complexity of neurons and use cell measurements to "predict" the activity and function of those cells, which are now available for 633 neurons in the database.

Additionally, more sophisticated neuronal models based on cell shape, morphology and subcellular components are now available for hundreds of neurons via an interactive web browser.

The Allen Cell Types Database contains detailed descriptive features gathered from individual neurons in the mouse brain, including location, electrical activity and shape. For this release, electrophysiological recordings from an additional 130 cells from the cortex have been added to the database.

The Allen Cell Types Database (celltypes.brain-map.org) is a fundamental resource of the Allen Institute's ten-year plan to understand how activity in the brain leads to perception, decision-making and action. Understanding cell types--the brain's building blocks--is critical to making sense of both how the healthy brain functions and what goes wrong in diseases such as autism, Alzheimer's and Parkinson's.

Additional updates to Allen Brain Atlas resources are planned for June and October of 2017.

About the Allen Institute for Brain Science

The Allen Institute for Brain Science is a division of the Allen Institute, an independent, 501(c)(3) nonprofit medical research organization dedicated to accelerating the understanding of how the human brain works in health and disease. Using a big science approach, the Allen Institute generates useful public resources used by researchers and organizations around the globe, drives technological and analytical advances, and discovers fundamental brain properties through integration of experiments, modeling and theory. Launched in 2003 with a seed contribution from founder and philanthropist Paul G. Allen, the Allen Institute is supported by a diversity of government, foundation and private funds to enable its projects. Given the Institute's achievements, Mr. Allen committed an additional $300 million in 2012 for the first four years of a ten-year plan to further propel and expand the Institute's scientific programs, bringing his total commitment to date to $500 million. The Allen Institute's data and tools are publicly available online at http://www.brain-map.org.

#492 Flint Water Crisis
This week we dig into the Flint water crisis: what happened, how it got so bad, what turned the tide, what's still left to do, and the mix of science, politics, and activism that are still needed to finish pulling Flint out of the crisis. We spend the hour with Dr Mona Hanna-Attisha, a physician, scientist, activist, the founder and director of the Pediatric Public Health Initiative, and author of the book "What the Eyes Don't See: A Story of Crisis, Resistance, and Hope in an American City".
