Background
In behavioral neuroscience research involving sleep, there is a need for automated state scoring to correctly identify how the experimental manipulations impact the state of the animal, including humans. Manual state scoring of physiological recordings in sleep studies is time-consuming, resulting in a data backlog, research delays and increased personnel costs.

Technology Description
Researchers at University of Michigan have developed MATLAB-based software to automate scoring of sleep/waking states in blocks of time. The program's graphical user interface allows the user to view power spectral densities for defined frequency bands of a small number of manually scored epochs in two 3D graphs in order to set thresholds by following written guidelines.

Applications
• Behavioral neuroscience research involving sleep

Advantages
• Open-sourced, hence easy to use
• Can be customized to user preference
• Accepts recorded data in a variety of formats, e.g., delimited text files, Excel files (Microsoft), proprietary files such as Neuralynx's Cheetah files, binary files and ASCII format files
