Unraveling Hidden Patterns of Brain Activity: A Journey Through Hemodynamic Deconvolution in Functional MRI
:::{note} Welcome to my PhD dissertation!
Thank you for your interest in my work. This website is a summary of my PhD dissertation and is the perfect place to learn about hemodynamic deconvolution in functional MRI: a technique that allows you to blindly estimate the neuronal-related activity without any knowledge of the timings of the neuronal events. :::

If you are interested in learning about the current background of the analysis of resting-state functional MRI data, please refer to .
If you are interested in learning about hemodynamic deconvolution and how it works, please refer to .
If you are interested in learning how you can make your estimates more robust without having to
select a fixed value for the regularization parameter
If you want to learn how you can exploit spatial information to improve your estimates of the activity-inducing signal, please refer to .
If you are interested in employing hemodynamic deconvolution to study the shared and individual responses of a group of subjects in a naturalistic paradigm, please refer to .
Finally, if you are interested in learning how you can reduce the bias of global components like the global signal or respiration-related artifacts from your estimates of neuronal-related activity, please refer to .
If you are interested in using the Python packages I developed during my PhD, please refer to the
Paradigm Free Mapping organization on
GitHub or click on the Packages
button on the top right corner of this page.

I would like to thank the Signal Processing in Neuroimaging (SPiN) lab at the Basque Center on Cognition, Brain and Language (BCBL) for their support and guidance throughout my PhD and I would like to especially thank my supervisors, Dr. César Caballero-Gaudes and Dr. Miguel Ángel Veganzones, for their support and guidance.
If you have any feedback or questions, please feel free to reach out to me at eurunuela on X or by opening an issue on the GitHub repository of the package you used.
