Project Title

Whole-brain molecular axes encoding relative spatial location in the human brain

Brief Project Description

There is strong evidence for large-scale genomic gradients helping to organize the spatial distribution of function in the brain, but this topic is very difficult to study in humans. We use PLS to define spatial gradients of gene expression in the adult human brain, and we explore how these gradients emerge of ontogeny and phylogeny, how they relate to topological brain features, how they may influence different traits, and what their relationship is to cell fate.

Code documentation

Every single aspect of preprocessing, sample selection, analysis, plotting, etc has be thoroughly documented and annotated within 9 Jupyter notebooks, which can be found in the Git repo. These can be run in order (most importantly the first 3 notebooks), and all data and code necessary to execute them is avaialble within the repo or instructions are given on how to download necessary data from public repositories. Instructions for cloning python environment are provided in the documentation on the github repo. Since all of these analyses are based on public data, reproducing my environment, following the instructions and running the notebook should be sufficient for completely reproducing every aspect of the manuscript.
