Description:
With the growing awareness of the neurological effects of many environmental chemicals there is considerable emphasis being placed on the detection of neurotoxic potential at the screening, or first-tier, level of testing. e have developed a neurobehavioral screening battery consisting of a functional observational battery (FOB) and an automated measure of motor activity which can be incorporated into neuropathological studies as well as general toxicity assessments of new and existing chemicals in rats. This approach has been recommended by several expert national and international panels an-has recently been recommended by the US Environmental Protection Agency for testing pesticides and industrial chemicals. he FOB consists of a series of home-cage, open-field, and interactive assessments of the rat's behavior and neurological functions. Motor activity provides an objective apical measure of the rat's neurobehavioral function. n order to assess validity, sensitivity, and specificity, we have utilized these test methods to determine dose-response and time-course characteristics of a wide variety of chemicals including pesticides, metals, solvents, and industrial compounds. We are currently developing approaches to provide profiles of effect for different types of neurotoxicants, which can then be used to make decisions concerning neurotoxic potential and provide direction for more in-depth, second-tier testing.
