Hiya,
I might know some of the neuroscience people, depends what area - that wasn't my undergrad course but they did mix about a bit. My undergrad dissertation was neuroendocrinology if that's any closer! Will you be based at the vet school in southwell st or somewhere else (not sure where all the neurosci research is done). I remember going to see Bristol on a couple of open days before I started, it rained, both times so I didn't get that great an idea of the city. But I personally think it is a fabulous place, Redland is gorgeous, Clifton is lovely. The bars down Whiteladies Rd and Park St are ace too. There's also the downs at the top of Whiteladies Rd / Blackboy Hill which are brilliant to escape too when you need some fresh air. I really enjoyed living there and fortunately still have friends there I can go and visit so I can escape London for a bit. Any questions feel free to throw them in my direction, as you can tell I am slightly biased though
