Tutorial FHS Neuro Spatial Hearing

 

Tutor Dr. Jan Schnupp,

Tel (2)72513  or (2)78889

E-mail jan.schnupp@physiol.ox.ac.uk

 

Venue:

 

Unless otherwise agreed, the tutorial will be held in room “Besse 7” of St Peter’s college.

Essay Question:

 

How is the spatial location of a sound source encoded in the central nervous system?

 

Note: Do not write more than 7 pages! If you want me to read your essay before the tutorial (which might be in your interest, because it would allow me to tailor the tutorial to your needs) then it would be great if you could let me have them at least 24 hours in advance, but don't worry too much if your essay doesn't get finished in time. Do make sure you've done a fair bit of reading before the tutorial though. This is meant to be your chance to ask questions, so while you are doing your reading, make notes of anything that is unclear, or highlight passages in the literature you don't understand.

My preferred mode of receiving essays is by e-mail attachment, but if you don't word process your essay then you can pidge them either to Physiology or St Peters.
