5-HT1BMB05181 adults shows the following locomotion defects in walking assays compared to controls: a significant increase in walking distance; significant decreases in the time inactive and maximum time inactive; but insignificant changes in the time spent in the center of the assay plate, number of clockwise movements, number of shifts between active/inactive state, time active and maximum time active.
5-HT1BMB05181 mutants exhibit an approximate 50% reduction in short-term memory.
5-HT1BMB05181 mutants do not exhibit a deficit in odor or shock reactivity.
