Introduction
Brainbrowser is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
BrainBrowser is a web-based visualization tool developed by the [Allen Institute for Brain Science](/institutions/allen-institute) that enables researchers to explore and interact with neuroimaging and brain atlas data directly in a web browser [@pierre2014]. The platform provides a lightweight, browser-based alternative to desktop neuroimaging software, making it particularly valuable for researchers who need to visualize brain data without installing specialized software [@allen]. [@allen]
Key Features
Volume Viewer
BrainBrowser's Volume Viewer enables 3D visualization of brain volumes with interactive rotation, zoom, and pan capabilities [@pierre2014]. The viewer supports multiple overlay layers, allowing researchers to superimpose different imaging modalities such as MRI, PET, and DTI data. Real-time rendering is achieved using WebGL, which leverages GPU acceleration for smooth performance even with large volumetric datasets [@allen]. [@lein2007]
Surface Viewer
The Surface Viewer displays brain surface models including cortical thickness visualization, sulcal depth maps, and curvature data [@pierre2014]. Researchers can explore the complex geometry of the cerebral [cortex](/brain-regions/cortex) and examine structural variations across individuals or experimental conditions. [@hawrylycz2012] ...

Connectivity Viewer
Streamline visualization in the Connectivity Viewer allows researchers to display fiber tracking data and diffusion tensor imaging (DTI) results [@pierre2014]. This feature is particularly useful for studying white matter tracts and brain connectivity patterns relevant to neurodegenerative diseases. [@brainspan2018]
Annotation Tools
BrainBrowser provides annotation tools that allow users to draw regions of interest (ROIs), measure volumes and areas, and export annotations for further analysis [@allen].
