About Me
Hi, my name is Tommy and I’m a postdoctoral student at the department of Anatomy and Neurosciences (Amsterdam UMC, location VUmc). My research uses computational neuroscience and network neuroscience to study brain network dynamics across diseases and disorders (main focus: multiple sclerosis and stress).
This page is mainly intended to provide a quick overview of my shared code. Feel free to contact me if you are interested in collaborating and/or applying any code to your own research!
Shared Code
This code will perform phase randomization on fourier transformed data, consistently across timeseries. This preserves static connectivity and n-lag autocorrelation, but time-dependent connectivity properties are randomized.
This code will perform community detection for multilayer connectivity matrices. The code is relatively computationally inexpensive and uses prior information on subnetwork organization to initialize/constrain the detection.
