Using Unidirectional Rotations to Improve Vestibular System Asymmetry in Patients with Vestibular Dysfunction Nayer Rassaian1, Navid G. Sadeghi1, Bardia Sabetazad2, Kathleen M. McNerney3, Robert F.

By directly modifying the vestibular pathway rather than enhancing the multisensory aspects of compensation, asymmetry can be normalized within 1-2 sessions and show lasting effects.
Operant Protocols for Assessing the Cost-benefit Analysis During Reinforced Decision Making by Rodents Mojtaba Kermani*1,3, Zahra Fatahi*2, Dechuan Sun3, Abbas Haghparast2, Chris French3,4 1Department of Optometry and Vision Science, The University of Melbourne, 2Neuroscience Research Center, Shahid Beheshti University of Medical Science, 3Department of Medicine, The University of Melbourne, 4Royal Melbourne Hospital A cost-benefit analysis is a weighing-scale approach that the brain performs during the course of decision making. Here, we propose a protocol to train rats on an operant-based decision-making paradigm where rats choose higher rewards at the expense of waiting for 15 s to receive them.
