How did you determine and refine your research interest to be as specific as possible? What kind of PIs did you reach out to? How did you go about requesting a supervisor? Whats big in the field of neuroscience right now?

Personally, I am interested in looking at neuronal regeneration and how it can be augmented or enhanced (plasticity, enhancing or replacing damaged tissue due to neurodegenerative disease or trauma, looking at factors that play a role in activating latent stem cells etc). Would like to work in a wet lab and look at something on the cellular level (at the synapse/genetic factors).

I'll be reaching out to PI's in order to find a potential supervisor and will try to incorporate some info from there publications into my correspondence. However, could you guys potentially help me with getting my research interest to be a bit more specific (if you feel its too broad), and assist with phrasing my correspondents in the best way possible.

Your research interests are probably as specific as they can be. People get more specific based on when they get their advisor, where the grant money is going, and what they can do someone in the lab isn’t doing.
