SUMMARY

The discussion centers on the impact of unshielded EEG cables on signal integrity in high-density electrocap recordings. It is established that while unshielded cables may introduce noise, the use of differential measurement techniques can mitigate this issue. The grounding of cables also plays a crucial role in maintaining signal quality, as visually appealing cables may not always provide effective grounding.

PREREQUISITES
  • Understanding of EEG signal acquisition techniques

Hi I have just received a high density electrocap for recording eeg -signals and discovered that the cable that leads to the electrodes is not shielded.
Does this probably corrupt the signal?

Hi,

It is possible that the unit uses a differential measure that lowers the noise.
And I saw many pretty cables that were well grounded but look like they weren't.
