[Eeglablist] Fw: BrainCap MR impedance values

I'm looking for some advice on impedance values using 64Ch Standard BrainCap-MR with multirodes. I'm planning on using the 64 channel cap for a concurrent EEG-fMRI setup and need to get a idea of what sort of impedance values can be tolerated before signal quality is compromised. As far as I'm aware there is already a 10kOhm impedance within the cap/connecting boxes. With this being the case what sort of overall impedance values are generally deemed acceptable?

Thanks in advance for any help anyone can offer on this.
