Area of Science:

Neuroscience
Biomedical Engineering
Genetics

Background:

Neurological disorders often impair balance and movement.
Current behavioral monitoring lacks scalability for screening.
High-throughput methods are needed for genetic and therapeutic screens.

Purpose of the Study:

To present a scalable apparatus to measure posture and locomotion (SAMPL).
To enable high-throughput screening for neurological disorder research.
To model balance and locomotor disorders.

Main Methods:

Developed extensible hardware and open-source software for real-time processing.
Designed to acquire data from D. melanogaster, C. elegans, and D. rerio.
Utilized vertical movement tracking for posture and locomotion analysis.

Main Results:

Defined zebrafish vertical navigation and balance mechanisms.
Identified systematic kinematic parameter variations across genetic backgrounds.
Demonstrated SAMPL's ability to resolve posture and navigation differences based on effect size and data volume.

Conclusions:

SAMPL is a scalable tool for posture and locomotion measurement.
The apparatus supports high-throughput screening for neurological disorder research.
SAMPL advances the modeling of balance and movement disorders.
