Simultaneous contribution of two rod pathways to AII amacrine and cone bipolar cell light responses.

abstract：:Seminal work in animals indicates that learning a motor task results in long-term potentiation (LTP) in primary motor cortex (M1) and a subsequent occlusion of LTP induction (Rioult-Pedotti et al. J Neurophysiol 98: 3688-3695, 2007). Using various forms of noninvasive brain stimulation in conjunction with a motor lear...
