What is computational neuroscience?

HUH???

Certainly fMRI is not what is normally meant by Computational 
Neuroscience. For sure if you answered a job ad as an fMRI person you 
wouldn't get a job if it was advertised for a computational 
neuroscientist (although few are).

fMRI and PET etc are regarded as Cognitive neuroscience or Human 
Neuropsychology.

Computational Neuroscience refers to making computational connectionist 
models of neural phenomena (e.g., neural networks).  Usually this is 
done either at the cellular level on electophysiological phenoma, or on 
vision phenomena in the visual system (the approach is relatively new 
and hasn't been used much otherwise). It is similar to computational 
biology but more constrained in its application, it also incorporates 
more elements of cognitive and computer science than computational 
biology.  There is a good book introducing the field by Sejnowski and 
Churchland (the book is called computational neuroscience).
