V is now the value of a reinforcer delivered after a variable delay, where there are n different possible delays to reinforcement. Pi is the probability that a delay of Di seconds will occur on any given trial. Mazur (1984) obtained fairly good predictions if K was set equal to 1, and this value of K will be used throughout this paper. To see how this model can be used to make specific predicti...

Remyelination failure plays an important role in the pathophysiology of multiple sclerosis, but the underlying cellular and molecular mechanisms remain poorly understood. We now report actively demyelinating lesions in patients with multiple sclerosis are associated with increased glial expression of fibroblast growth factor 9 (FGF9), which we demonstrate inhibits myelination and remyelination ...
