Interests
Brain mechanisms underlying behavioral change, especially the change associated with habituation and conditioning.
Two major areas of research focus:
- Acoustic startle response: long-term habituation, associated cardiovascular changes, sensitization, and the modulating effects of fear conditioning.
- Assessment of medial cerebellar damage with particularly attention to the "emotional" changes associated with cerebellar damage.
