Special Offer

 

We have a special offer for subscribers of "The FUNNI Pages."
 If you are a user of the FieldTrip Toolbox ( FieldTrip is the MATLAB software toolbox for MEG, EEG and iEEG analysis), or want to try it out (its free!) we are offering an aid to make it easier to remember all the commands and their options: a Fieldtrip Cheatsheet! It summarizes all the data formats, routines, and configuration options in a printable PDF file.

 This is available exclusively to subscribers of "The FUNNI Pages." You can see an example page of the cheatsheet here.

 If you want to be sent a PDF file containing the FieldTrip Cheatsheet, send us an email request and we will send it to you.

New MSR field cancellation product


Candoo Systems is pleased to announce that we can supply a field cancellation system for existing MEG magnetic shielded rooms (MSRs) that reduces the remnant DC field to less than 1 nT typically. This allows the use of OPM MEG systems inside the MSR. The system uses proven technology and is completely external to the MSR.

  • A very interesting report on the results of experiments with "fingerprinting" people based on their brain connectome during rest and task-related activity using MEG recordings. The authors conclude that it is possible to identify individuals with some confidence using MEG, and that performance is significantly enhanced during tasks. This is a long and detailed paper, and it seems like a promising area for research. I would have liked to see the authors compare the results using MEG to previous results reported using other modalities.

Interesting Reading

E. Strickland, "A Bionic Nose to Smell the Roses Again", IEEE Spectrum Magazine, Nov/22, p. 22
This article illustrates the value of knowing the location of sensory function areas in the brain and how they are networked to other areas. The results from neuroimaging olfactory evoked responses has shown where it could be possible to apply the output of olfactory sensor prostheses via deep brain stimulation. This potentially avoids problems with connecting directly to the olfactory bulb.
It reminded me of seeing a bulky apparatus being used for taste sensory stimulation in an MEG lab in Japan during the 1990's. I wonder what results came of that?
