Tests and Equipment

Neurophysiological screen is a series of tests for neonatal, juvenile, or adult mice that are conducted by trained observers for examination of general health and gross physiological responses, as well as assessments of gross sensory (vision, touch, taste, olfaction, audition) and motor functions.  In additional we can assess hearing at different intensities and frequencies (MedAssociates equipment).
