Very important voxels: optimizing ROI consistency with priority queues

Last autumn, I speculated about defining time-dependent, flexible nodes for functional brain networks. Many brain areas (or Regions of Interest, ROIs) that are commonly used as brain network nodes suffer from low functional homogeneity. In these ROIs, the voxels of the ROI behave differently in time. So, the ROI time series can’t accurately represent the …

#brainTC: The 3rd Brain Twitter Conference is coming!

Last time, I wrote about the importance of conferences in the academic life. Participating a conference is an opportunity to present ongoing work and gain feedback on it, to follow the trends of one’s field, and to meet new collaborators. However, the whole concept of conferencing may be about to change. Shall we in the …

The importance of being… at a conference

The description of this blog states that I’ll write about my research but also about the day-to-day academic life. This time, I’ll concentrate on an important aspect of the day-to-day part: conferences. What follows is based on my experiences from a bunch of more or less brain-networkish conferences over the last years. Conferences are essentially …

What happens inside ROIs… doesn’t stay inside ROIs!

In the second part of my wired brain saga, I discussed the concept of Regions of Interest, or ROIs. ROIs are collections of fMRI measurement voxels (or MEG and EEG source vertices) that are often used as nodes of functional brain networks. Earlier, we have learned that many ROIs have low functional homogeneity, meaning that …

Study useless things! (5 + 1 tips for future researchers)

Olen kirjoittanut vinkkejä tuleville tutkijoille myös suomeksi: “Opiskele hyödytöntä! (5 + 1 vinkkiä tuleville tutkijoille)”. During the coming weeks, I’ll have the pleasure to visit two Finnish schools: Sotunki Secondary School, to where I went in years 2001-2004, as well as my old high school, Viikki Teacher Training School*, from where I graduated in 2007. …

Opiskele hyödytöntä! (5 + 1 vinkkiä tuleville tutkijoille)

This is a Finnish version of my post “Study useless things! (5 + 1 tips for future researchers)”. Check here for the English version. Tulevina viikkoina pääsen ilokseni vierailemaan kahdessa entisessä koulussani: Sotungin koulussa, jota kävin vuosina 2001-2004, ja Viikin normaalikoulussa, josta kirjoitin ylioppilaaksi 2007. Näiden vierailujen innostamana kirjoitan tällä kertaa vinkkejä tutkijan urasta haaveileville. …

Stars of mitigation? Modelling collaboration with a bipartite network

The beauty of the network model lies in its versatility. A pretty limited set of tools allows studying a wide variety of different systems. For me, the versatility of the model opens side tracks that at the first glance are pretty far away from my main research field. Let’s walk down one of these side …
