Therefore, significant research funds have ONLINE: 04 Jan 2015 been allocated towards improving outcomes of patients suffering from brain disorders. In recent years, researchers have been facing a constantly growing worldwide pressure to make their datasets freely and readily available to other K E Y W O R D S: researchers and the public. The major goal of this movement is to allow re-use of already collected data in order to facilitate medical progress. There are numer- Open Access ous ways that clinical neuroscience researchers and research organizations Dataset commonly employ to make their databases available. Institutional databases and Brain Diseases publicly available research and clinical data repositories and registries are the Disease Models most common ways to share data among researchers and organizations in order Data Sharing to facilitate collaboration. In addition, numerous traditional neuroscience peer reviewed journals have implemented various data sharing policies. Furthermore, a few traditional clinical neuroscience peer review journals have recently started accepting dataset papers. Finally, there is a constantly growing number of data- base journals which accept clinical neuroscience research datasets for publica- tion. Potential for improving of citation metrics is among the important ad- vantages for authors considering publishing their databases in dataset journals.
