This project is targeted at testing the potential of brain morphometry for comparative evolutionary analyses, as discussed in

- Two related proposals on Comparative Primate Brain Morphometry have been rejected — one by the VolkswagenStiftung, another one (with added emphasis on an Open Science approach) by the Deutsche Forschungsgemeinschaft.
- An abstract, Optimizing automated processing streams for brain morphometric comparisons across multiple species, has been accepted as a poster at the Human Brain Mapping 2010 conference.
- At the conference, there will be a keynote on "Comparative Neuroimaging Across Species" (cf. http://www.humanbrainmapping.org/i4a/pages/index.cfm?pageID=3363 ) by Wim Vanduffel ( http://www.nmr.mgh.harvard.edu/martinos/people/showPerson.php?people_id=177 ), focusing on fMRI of the visual system
- There will also be a morning workshop "Multi-Subject Surface-Based Analysis of fMRI Data: Challenges, Solutions and Limitations" http://www.humanbrainmapping.org/files/2010%20Symposium_Workshops/Multi-subject%20surface-based%20analysis%20of%20fMRI%20data.pdf
- So far, most of the notes on this project have been taken on a private wiki, but we will see to move a larger fraction here in time for the project to start. Any comments or inquiries are most welcome.
- Media:Primate brain comparisons.xls contains two sheets:
- Marino 1998 Primate brain measurements: Mean brain weight, mean body weight, and mean brain weight/body weight ratio for 60 anthropoid primate species (adults, combined sexes), according to Tab. 1 in Marino 1998.
- There are also the following supplementary columns:
- Log brain mass;
- The latter two were calculated according to the formulas given on p. 112 in Holloway 1980
- Jerison’s  EQ, calculated from the equation EQ = brain weight/0.12 * body weight^0.666 ;
- Stephan et al.’s  EQ, calculated from the equation EQ = brain weight/0.0429 * body weight^0.63 ;
- Genetic distance, as taken from Fig. 3 of Xing 2007
- Note that there is an erratum for this paper (hidden at the end of this pdf; wasn't aware of it until now, but doesn't seem to affect the data taken from there): "In reference to ‘A Comparison of Encephalization between Odontocete Cetaceans and Anthropoid Primates’, by L. Marino, published in Brain Behav Evol 1998;51:230–238, the journal has been asked to print the corrected ﬁgure1. The axes in the original ﬁgure were reversed. In tables 1 and 2, the reference to mean brain weight/body weight ratios should be disregarded."
- Subjects: Names or labels of primate subjects (mostly from Rilling and Insel, 1998) for which I have MR data. For each subject, the data concerning its species is transferred from the previous sheet.
