Voxel – Wise Modelling in neuroscience.



There are references to it in most of the literature I’m going through.

If an is not possible, can you point me to resources that would help me understand it myself? (Any pre – reqs).


In: Biology

voxel is an analogy of pixel. Pixel stands for picture element, while voxel stands for volume element. I’m assuming that you know what is pixel. In case you don’t: [https://www.bbc.co.uk/bitesize/topics/zf2f9j6/articles/z2tgr82](https://www.bbc.co.uk/bitesize/topics/zf2f9j6/articles/z2tgr82)

There are many ways to model the brain. One way is to decompose brain in terms of voxels, since brain is 3d. You then can get a value for every voxel through various techniques such as MRI, fMRI, CAT, MEG, etc.

In an image, each pixel contains 3 values, each representing colors RGB. A voxel could also contain one or more values, depending on the imaging technique used. One example in BOLD signal in fMRI https://en.wikipedia.org/wiki/Blood-oxygen-level-dependent_imaging
