SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Progress in Neurobiology is designed to help individuals keep abreast of advances in knowledge in the broad field of neurosciences through the publication of comprehensive reviews by leading researchers. It will include the application of neurophysiological, biochemical, pharmacological, molecular biological, anatomical, and behavioral analyses to problems of molecular, cellular, developmental, and systems neuroscience. Special attention will be given to those areas where availability of new techniques has led to a multi-disciplinary approach to the problems of the nervous system. It is the intention of the Editor-in-Chief that the reviews should be of sufficient clarity to be suitable for assimilation by doctoral and postdoctoral students as well as by research scientists in neuroscience and allied fields. The authorship is international.
