I did a summary of about 3 para's (about 20 lines). Then I did a table of comparison between the human & canine brain from facts gleaned out of the researched books. I cannot help you too much on references as the feedback comment on my answer was "Good - don't forget your references though" Ooops!! Plus I did not write that the dog's olfactory bulb is larger than ours.
I have a list of references used at the end of my module, but now I am beginning to realise the benefit of referencing as you go, as I could not say for sure from my list which ones I used for what questions! Apart from the usual Canine related books on the Reading List, or similar, I think the human anatomy books -as usual- I referenced/borrowed from the library so may not be available in all diferent library databases anyway?
I hope your next attempt gets you back in the swing of thing.
