NDT Colleagues:
Does anyone in the NDT profession have a WORKING old Grass PS-22 (see photo) that I can borrow? If not, does anyone have a manual free-standing photic stimulator (non-software controlled)?
Reason ...
I'm doing a control study on optimal parameters for monocular and binocular steady-state visual stimulation. I am also comparing traditional signal averaged VEPs versus rapid frequency-domain Fourier analysis.
Under the proper anesthetic conditions, visual cortex (Area 17) sustained responses to steady-state dichoptic flash stimulation are easily recorded.
I believe ... these responses will not only indicate a grossly intact visual pathway, but (based on the temporal tuning characteristics of the retina), such responses can be used to separate magnocellular and parvocellular responses and thus predict if the sub-pathway needed for normal spatial resolution (normal vision) remains intact during the course of high-risk neurovascular or tumor resection surgeries.
In short, this is a hopeful recording technique that can be configured to run on any Cadwell, Medtronic, or XLTec ... and more importantly it may help to reduce the likelihood of intraoperative loss of vision.
This technique is an improvement to the traditional flash transient VEP that has been used for years in the clinic and has been attempted in several other surgical studies with little success.
I actually used a similar technique back in the late 1980s on infants with bilateral latent nystagmus and congenital cataracts with good post-op predictive success.
Friends in IONM, I need some help. I know some of you out there work in the outsourced/contracted IONM setting. And, you are forced to wear the way-too-big paper scrubs, red cap, visitor badge, etc. As some of you know, I'm trying to fight this trend because I think it erodes teamwork and endangers patient safety. I'm giving a very important talk to some decision makers in the surgical world in a couple weeks, and I'm looking for some photos to drive home the point. The more ridiculous you look, the better. I'll need permission to use your photo in the talk though. If anyone has, or can get, a good photo, please send through FB messenger, or inbox me and I'll send you my email address. Thank you so much for reading!!!
I have an exciting and ambitious agenda planned for the year ahead at the ASNM, and for the entire neuromonitoring profession. Come to Chicago and hear my incoming President's speech at the ASNM Annual Meeting May 3-5, 2019!! #ASNM #president #neuromonitoring
If you perform IONM, please come and give your input regarding proper protocols on a new group site.

Brett Netherton clearly demonstrates the superior reduction of noise (from devices with directional EMF) in the OR by using parallel ribbon-paired electrodes and twisted pair electrodes versus loosely paired single electrodes.
