user16651: I have been seeing a number of questions come up that are more neuroscience related and are likely more appropriate for Cognitive Sciences SE. 
I realize that this has come up before in this Biology Meta SE question (Redirect more people to Cognitive Sciences SE?), but it is now 1 year 8 months later and CSSE is likely more established. 
Looking at their Area 51 Stats, it appears that the community is doing very well, but could use to up their daily number of questions. Having the ability to flag questions to redirect them to that site would help them get passed the Beta phase as well as give the questions a better chance of receiving a quality answer.  
EDIT
While there were a couple of posts rolled up in this discussion, this was the question in particular https://biology.stackexchange.com/questions/39914/can-anyone-see-what-is-wrong-with-this-implementation-of-the-pinsky-rinzel-model that prompted me to post this.
I understand the difference between questions that can be answered here and those that really should be there, and I think that the moderators understand that as well. It is sort of like this xkcd piece:

xkcd: Purity
We have a flag to move to chemistry, so that either leaves us using the mod flag or just ignoring the question entirely. I don't think that is a good thing for either site or for the OP.

user9943: The overlap between the sites has been a topic of much debate. A recent meta post there has pointed out the consensus that every basic Neurobiology question is on-topic there (albeit it may fit Biology just as well, and arguably even better). More importantly, there is an active voting procedure ongoing there to change the name of the site and it looks PSYCHOLOGY AND NEUROSCIENCE is the big winner. They are indeed in need for more questions, as @AMR rightfully pointed out. More importantly, however, the name change is quite necessary, because the site has been accepting basic Neuroscience questions for a long time (addressed here) and is actively welcoming them now. "Cognitive Sciences" is a deceptive site name indeed, and its unfortunate name has kept me from becoming active on the site for quite a while.
Having said all this, I think we should never consider migrating basic Neuroscience questions to CogSci. I think the consensus will eventually be that Neurobiology is where Bio and CogSci overlap. They do so now, and they will likely do so in the future. In terms of neurophysiology, folks are better off here at Bio given the expertise here. In terms of behavior, they are better of there. But in terms of ontopicness, they fit both sites. Being a neurobiologist focusing on electrophysiology and psychophysics, I cover the Neurobiology area-of-overlap. The pitch of my answers at CogSci and at Bio is not so different and they are (generally :-) welcomed on either side.   

user3340: We should have a consensus here. I do not think flagging every neuroscience related question cogsi.se is a great idea. There are specific areas that that suit cogsci.se better. I think we can migrate questions on following subjects:

Behavioural studies
Social neuroscience
Psychology
Neuropsychology
Psychiatry 

We need not migrate neurophysiology, neuroanatomy and molecular neuroscience questions because we have users who have expertise in these areas.
