Songbirds learn to sing by memorizing a tutor song that they then vocally mimic using auditory feedback. This developmental sequence suggests that brain areas that encode auditory memories communicate with brain areas for learned vocal control. In the songbird, the secondary auditory telencephalic region caudal mesopallium (CM) contains neurons that encode aspects of auditory experience. We investigated whether CM is an important source of auditory input to two sensorimotor structures implicated in singing, the telencephalic song nucleus interface (NIf) and HVC. We used reversible inactivation methods to show that activity in CM is necessary for much of the auditory-evoked activity …

Theses and Dissertations (Comprehensive)
Animal studies using the self-administration paradigm suggest that duration of drug access (Ahmed, 2005) and individual phenotype (Piazza, Deminiere, Le Moal and Simon, 1989) are important factors in the development of drug addiction. Wheel running in rats has been proposed as a model to study non-drug addictions (Eikelboom & Lattanzio, 2003). When first given ad lib wheel access, young male rats initially run at low levels (about 1000 wheel turns per night) and gradually increase this distance to high levels (about 5000 wheel turns per night) (Afonso and Eikelboom, 2003). Like with self-administration, duration of wheel access has been found …
