How does it feel to write a second PhD

Public and private Last week i had the viva for my Dr.rer.nat. To be specific, it was a sunny afternoon on a tuesday, the 28th of march 2017. We drew a small crowd. Not only did i defend in front of four professors. It was also a public event, and because my colleague and friend… Read more »

Boundary element models of several brain areas

Put Shortly: If you want to perform source reconstruction for a region of interest, and therefore ignore some of the grid points of an evenly spaced source grid, these boundary-element models of several brain areas might be useful. In a previous post, i described how to construct a symetric headmodel based on the ICBM152 template… Read more »

Is the p-value a good measure for the weight of statistical evidence?

Many researchers naively follow the concept that a p-value below a certain threshold (traditionally .05)  is to be considered significant, and can therefore be considered as evidence that H1 is true, while a p-value above that level is considered not significant and therefore evidence that H0 is true. This Neyman-Pearson approach to statistical testing is… Read more »

Cheap probe for the magnetic field induced by your TMS

I wanted to check the timing of a TMS-protocol using an external trigger, and sometimes i want to demonstrate the current induction in class. MagVenture sells the MagProbe, to be plugged into BNC or DIN. This would allow you to measure the magnetic field induced by the TMS. They also offer a 3-D version, and… Read more »

Connecting BVR, Magventure and Localite – Make the Box

In an earlier post, i described how to connect Brain Vision Recorder, a Magventure TMS and Localite Software. In a later post, i describe how to solder the circuit. This would allow more flexible recordings  according to your uniqe needs, e.g. multi-channel MEP mapping. As i am currently constructing another box for our second TMS-device,… Read more »

Connecting BVR, Magventure and Localite – Discussing the Idea

Recently, our lab purchased two MagVenture TMS devices together with the Localite setup for navigation. Both companies are independent, but collaborating strongly. Magventure offers the stimulator, Localite the hardware and software for navigation. The Magventure GUI is very easy to handle and i like how the Localite software allows to use template MRIs. It gives… Read more »
