Plexon’s “Following Protocol”
Linear Probe Discussion with Prof. Dr. Pascal Fries
My question is for beginners, which probe would you recommend for optogenetic simulations, and how many channels are minimum for reasonable recordings?
“So I guess this now pertains to the laminar probes from Plexon, we have clearly the best experience with V-Probes, we have also tried S-Probes, in our hands, the unit recordings are particularly crisp with V-Probes, I think generally the S-Probes have been recommended for penetrating the dura, I showed you that at least with this approach that has been developed in my lab by Eleni Psarou, we can use a… guide tube and we can reliably penetrate the dura even though we are typically not
Do you implant ECoG arrays below dura? Have you compared epidural and below dura responses?
“Yes, so in the awake macaque monkey we have implanted them subdurally I
Do you think the optogenetic induced gamma in cat striate is similar to an arousal input, for example, electrical MRF stimulation, as shown in 1996 and 2004 by Singer and colleagues?
“Absolutely so you’re referring to the work of Matthias Monk
