Neuropeptide S Enhances Memory During the Consolidation Phase and Interacts with Noradrenergic Systems in the Brain Responses to rapid-rate transcranial magnetic stimulation of the human motor cortex Levodopa increases memory encoding and dopamine release in the striatum in the elderly Focusing effect of acetylcholine on neuroplasticity in the human motor cor Levodopa improves skilled hand functions in the elderly Levodopa improves procedural motor learning in chronic stroke patients Increasing dopamine levels in the brain improves feedback-based procedural learning in healthy participants: an artificial-grammar-learning experiment Simulating neurocognitive aging: effects of a dopaminergic antagonist on brain activity during working memory Better than normal: improved formation of long-term spatial memory in healthy rats treated with levodopa Representation of goal and movements without overt motor behavior in the human motor cortex: a transcranial magnetic stimulation study Representation of Goal and Movements without Overt Motor Behavior in the Human Motor Cortex: A Transcranial Magnetic Stimulation Study Chronic repetitive transcranial magnetic stimulation increases hippocampal neurogenesis in rats Non-primary motor areas in the human frontal lobe are connected directly to hand muscles Emotion induction after direct intracerebral stimulations of human amygdala http://www.sciencedirect.com/science/article/pii/S0092867412004618
