Purkinje cell loss by OX7-saporin impairs excitatory and inhibitory eyeblink conditioning.

Nolan BC, Freeman JH Jr (2005) Purkinje cell loss by OX7-saporin impairs excitatory and inhibitory eyeblink conditioning. Behav Neurosci 119(1):190-201. doi: 10.1037/0735-7044.119.1.190

Summary: Although the contributions of the cortical cerebellum to eyeblink-conditioned excitation have been extensively investigated, involvement in inhibition of this reflex is unclear. After intracerebroventricular infusions of 15.0 µg of OX7-SAP (Cat. #IT-02), rats displayed impaired retention and savings of preinfusion excitatory conditioning, indicating that the Purkinje cells that were eliminated by OX7-SAP are essential for maintenance of excitatory eyeblink conditioning. Inhibition is not prevented by loss of these Purkinje cells, suggesting that extracerebellar structures play a critical role in this process.
