Unique characteristics
- Incomplete Circle of Willis
- Require sand bath
- Nasal dermatitis @ humidity >50%

- Tail degloving occurs: DO NOT pick up by tail
- Seizures: 20-40% by 2 mo old; in response to sensory stimulation & forced exploratory behavior

Uses in research?
Microtus sp (Vole)
M. orchrogaster used to study physiology of vomeronasal organ and how chemosensory cues affect courtship, territorial marking, aggression, and reproduction. Also, M. ochrogaster is monogamous, and studies have focused on neuropeptides oxytocin and vasopressin control of pair-bonding, paternal care, maternal care, and mate-guarding.
M. pennsylvanicus is polygamous and somewhat antisocial and is used as a contrasting species in the above studies.
