Here is a great resource for graduate programs in Neuroscience that can be found at the Neuroscience Departments and Program Directory from the Society for Neuroscience. You'll find a list of universities with Neuroscience graduate programs, their contact information, and their departmental websites.
Please find a list of Post-Baccalaureate Research Programs that should be helpful for Neuroscience students who might be considering graduate school. This is a great way to see what it's like to do research (before entering a graduate program)!
