Background
This project (funding decision pending) is targeted at testing the potential of brain morphometry for comparative evolutionary analyses, as discussed in
- Mietchen D and Gaser C. Computational morphometry for detecting changes in brain structure due to development, aging, learning, disease and evolution. Front Neuroinform. 2009;3:25. DOI:10.3389/neuro.11.025.2009 |
Current state
- One proposal for a project on Comparative Primate Brain Morphometry has been rejected by the VolkswagenStiftung, another one (with added emphasis on an Open Science approach) is currently under review at the Deutsche Forschungsgemeinschaft.
- 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.
Associated files
- 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;
- EQ_Jerison
- EQ_Stephan
- The latter two were calculated according to the formulas given on p. 112 in Holloway 1980
- Jerison’s [1973] EQ, calculated from the equation EQ = brain weight/0.12 * body weight^0.666 ;
- Stephan et al.’s [1969] EQ, calculated from the equation EQ = brain weight/0.0429 * body weight^0.63 ;
- Genetic distance, as taken from Fig. 3 of Xing 2007
- Subjects: Names or labels of primate subjects for which I have MR data. For each subject, the data concerning its species is transferred from the previous sheet.
- Note that there is an erratum for this paper (hidden at the end of this pdf; wasn't aware of it until now): "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."
