As part of our work in comparative anatomy, we collect diffusion MRI data from non-human primates. These data are obtained from animals that have died of causes unrelated to us and unrelated to our research. We obtain them from zoos and research institutes that in this way continue to contribute to our knowledge of these animals.

Obtaining these data is expensive, both in money and time. It requires combined expertise from veterinarians, physicists, statisticians, and neuroscientists. As such, obtaining these data is an endeavor that has taken many years to set up.

In the long run, we strive to make all data freely available. In the meantime, we started making some data freely available and some under more constrained circumstances. This is due to the tremendous amount of work it takes to acquire these data and the fact that some of these data are obtained through collaborations with their own requirements and constrains. Therefore, although we fully support open science, access to the data sometimes takes longer than anticipated.

Below is a list of data that are already available and the circumstances under which external parties may obtain it.

Macaque (Macaca mulatta)

The macaque monkey is the most studied non-human primate. The PRIME-DE data repository (Milham et al., 2018) contains a variety of neuroimaging data from this species. We have uploaded post-mortem diffusion MRI data from six macaques to this repository.

The data can be accessed from PRIME-DE.

Chimpanzee (Pan troglodytes) and Gorilla (Gorilla gorilla)

Great apes are our closest animal relatives. They are in most cases endangered and their conservation is a top priority. We have obtained some samples on loan from zoos after the animals died and scanned these on a human 7T MRI system. These data were first used in Roumazeilles et al. (2020).

We do not want these data to spread around completely uncontrolled, but are open to making them available in a collaborative fashion and/or upon reasonable request and after agreement of our partners. If you are interested, please contact us.

Eight primates from the Primate Brain Bank

The Primate Brain Bank stores brain tissue from non-human primates obtained from zoos after their death. This is a great initiative that allows us to learn a lot from the brains of a wide variety of primates. We scanned the brain of eight species:

- Galago senegalensis (Senegal bushbaby)

- Pithecia pithecia (White-faced saki)

- Lagothrix lagotricha (Woolly monkey)

- Sapajus apella (Tufted capuchin)

- Aotus lemurinus (Night monkey)

- Colobus guereza (Black-and-white colobus)

- Lophocebus albigena (Grey-cheecked mangabey)

- Pan troglodytes (Chimpanzee)

These data are published in Bryant et al. (submitted) and will be released on the WIN's Digital Brain Bank soon. If you are interested, please contact us.
