About the Core

Content

The goals of the preclinical phenotyping component of PCO Core include: 

a) Expert consultation for experimental design and data analysis
b) Training for specific assays provided by expert staff
c) High-quality, efficient, and cost-effective service
d) Educational workshops on various topics and data analysis, technical issues, trouble-shooting, topics in behavioral neuroscience/genetics
e) Innovation and development of novel assays as preclinical outcome measures.

We have two rodent neurobehavioral core facilities located on BCM Main Campus and in the Jan and Dan Duncan Neurological Research Institute encompassing ~5,000 sq.ft. of space dedicated to behavioral studies of rodent models of disease. Our cores for mouse model studies have 32 rooms available for testing, containing state-of-the-art equipment to evaluate behavioral domains such as anxiety-like behavior, mood, multiple aspects of motor function and coordination, various learning/memory paradigms, social behavior, vocalization, pain, perseverative behavior, circadian activity as well as whole body autonomic measurements such as unrestrained plethysmography.
