The Battelle Neurobehavioral Laboratory has state-of-the-art facilities for high-throughput testing. Our highly qualified staff has proven experience in the full range of neurobehavioral testing options.

Tier I Testing
mouse(Functional observational battery (FOB) or modified Irwin test) Tier I testing provides the initial investigation into potential neurotoxic effects. Tier I testing utilizes a battery of home cage, handling and open field tests to screen for potential neurotoxicity and includes:

  • ~40 tests to assess excitability, neuromuscular coordination, general activity, posture, grip strength, presence of tremors or convulsions, autonomic nervous system function, spontaneous activity, motor activity, arousal, sensory/motor reflex responses and body temperature

Tier II Testing

More sophisticated behavioral testing when triggered by concern from Tier I tests. The goal of Tier II testing is to characterize the nature of neurotoxicity seen in Tier I by quantifying effects on motor function, sensorimotor function and cognitive behavior using complex tasks. These include:

  • Locomotor Activity Assessment: Motor Monitor System
  • Sensorimotor Gating: Acoustic Startle System
  • Motor Coordination: Rotarod/Accelarod Units
  • Gait Analysis: DigiGait Imaging Device
  • Learning and Memory: Morris Water Maze
  • Anxiety and Emotionality: Elevated Plus Maze
Tier III Testing

  • EEG with simultaneous behavioral monitoring capability
  • Special staining for detailed neurohistopathological analysis


When you come to Battelle, you’ll find world-class expertise and dedicated, state-of-the-art facilities with everything you need to complete your study, from initial study design to regulatory support. And if your study requires an approach beyond the ordinary, don’t worry. At Battelle, we don’t just collect data – we solve problems.
