Developmental and genetic variables in mouse startle response habituation

A behavioral task insensitive to inherent sensory and motor limitations, specifically a startle response habituation technique, was used to investigate genetic (strains) and developmental (age) effects on behavior. All mice tested using two procedures exhibited evidence for habituation which was dependent on strain, age, and length of the testing process. Exploitation of this simple technique may permit clarfication of more complex types of behavior.
