Yeah, I also feel the same thing - that many people are applying for Neuroscience programs. I actually just joined Grad Cafe, so, I haven't read that many posts yet to see if many people on here are also applying for the neuroscience program as well.
I just feel that neuroscience is increasing in popularity. Currently, the Brain Project is going on and even MOOC's, such as Coursera, have recently started to offer neuroscience courses. I took the Medicinal Neuroscience course with Dr. Leonard White on Coursera and it was a really good course. I also agree a lot with basically everything 'pasteltomato' said. Many people conducting research in neuroscience are in interdisciplinary studies.
