Tough question my friends... I believe that we will be free of sharing our data, but not for whatever use. We should be aware of the interest conflicts, the bad use of the data, the appropriation of the data or even the burglary of the projects. All persons that wanted to see the data, they should have access, is the way to demonstrate that the data was obtained in the right way, however when we sharing for reuse we should be clear and make the statement that the data is from another experiment or is used to compare models or results from different experiments. Science it should be clear and directed to the understanding of all natural phenomena, we can't ignore the past, the old experiments, the old data because all of this are the founding of the actual science, that means that we are allowed of compare the data, but we are obligated to use it in the right way... Sharing data in neuroscience is good for many reasons, we can compare experiments, we can run different algorithms to find new perspectives, we can learn about the way in which the data were obtained, etc. However not always its will be in that way, sometimes somebody could use it in bad way, but if we are aware of that possibility and we are prepared to claim the rightness of the data, with back ups of the data, laboratory notes, video recordings, the original projects etc, we can be victorius in this hard, but honorable quest.
