Is ActiView really open source ?

Dear Coen, In order to modify the "Avg-sweep" subroutine, I downloaded the original package from your website "Actiview605-all", and opened the vi using a full version of Labview (v10) after placing the files in the Labview data folder. I was able to open and modify the subvi "Avg-sweep" but it was ...

Coen, Can you just check the following steps as I am not familiar with the structure and labels of the ActiView software ? I have identified the subvi Avg-Sweep.vi as the critical part of the source code. I guess that I have to remove the "+" that relates the content of the "Average Buffer" to the c...

Artefact of the TMS pulse and MEPs

Hi We have recently started using on-line TMS while recording EMG activity in hand and arm muscles with the BioSemi system (flat electrodes). When TMS is applied over the hand motor cortex, a motor-evoked potential (MEP) is typically observed in hand muscles 20-30 msec after the pulse (earlier in th...

using triggers to start/stop the display (not the saving)

Hi I have recently started using BioSemi to record TMS-induced motor-evoked potentials (MEPs) in hand muscles. We define TMS intensity as a function of the motor threshold, minimum intensity to observe a MEP > 50 microV in 5 out of 10 trials. Fast and efficient calibration thus requires on-line visu...
