Have you used our open science resources?

The Brain? IDK! What we know and don’t know about brain cells.


Join us to learn more about what we don’t know about the brain!

Why are we talking about what we don’t know rather than what we do know? It sounds counterintuitive, but understanding where gaps in knowledge exist in our understanding of the brain helps to guide future research here at the Allen Institute and across the field of neuroscience. The goal of this research is to gain insights into how the brain works so that we know better ways to fix it when something goes wrong.

This event is geared towards adults across the community and is suitable for audiences high school and up.

*We strongly recommend pre-registering to guarantee space at the event. Limited walk-in capacity will also be available.*

*This event is FREE*

About This Event

At this free public event, scientists from the Allen Institute for Brain Science will discuss what we do and don’t yet know about brain cells, potential applications of more detailed knowledge of brain cells and the Allen Institute’s open cell type resources, and what tools and techniques the Allen Institute is using to attempt to fill these gaps in our understanding. Attendees will have the opportunity to participate in hands-on activities, such as a model of how we organize cell types data and real brain slices used in our research!

Refreshments will be provided.

This event will not be livestreamed, but a recording will be posted to the Allen Institute YouTube channel shortly after the event.

Parking is available in the Allen Institute garage (entrance at 943 Roy St) but it will not be validated by us. The rate is $6.00 for the first hour, $3.00/additional hour. There is additional street parking around the building.

Rachel Hostetler, Ph.D.

Rachel is a Scientist I on the Scientific and Public Outreach Cell Type Taxonomy (SPOCTT) team. Her role in this team is to make the Allen Institute’s cell taxonomy tools and resources more accessible to scientists and the public. Rachel completed her Ph.D. at West Virginia University, and her work studied the diversity and connectivity of inhibitory interneurons using mouse models and high-resolution microscopy. In her work, she used many of the Allen Institute resources that will be highlighted at this event!

Jeremy Miller, Ph.D.

Jeremy is a senior scientist at the Allen Institute for Brain Science and principal investigator (PI) on the Scientific and Public Outreach of Cell Type Taxonomy (SPOCTT) team. His primary focus is on developing computational tools and standards that make knowledge about brain cells in adult and aged donors more accessible to other scientists. Prior to this work, he co-first authored several major manuscripts describing the Allen Institute’s gene expression resources. He received his Ph.D. in neuroscience from UCLA where he studied gene expression changes in the brain in Alzheimer’s disease and normal aging.

3,000 Types of Brain Cells Categorized in Brain Cell Atlas

In October 2023, an international group of scientists released an impressively detailed cell atlas of the human brain.

The background is filled with mathematical equations and formulas in white against a blue digital space, conveying a theme of intelligence, data processing, or scientific analysis.

What makes us human? Cellular maps of brain reveal clues

Scientists have just unveiled a massive effort to understand our own brains and those of our closest primate relatives.

How Single-Cell Omics is Revolutionizing Neurobiology

Understanding the diversity of brain cells and their gene-regulatory mechanisms is key to determine how the brain works.
