Influence of G-CSF and EPO on Associative Learning and Motor Skills

Summary

In the study we want to prove whether the subcutaneous application of granulocyte-stimulating factor (G-CSF) and erythropoetin (EPO) influence associative learning and/or motor skills of patients, who suffer from chronic stroke or amyotrophic lateral sclerosis. The study hypothesis is that G-CSF and EPO improve associative learning and/or motor skills.
