Can GCaMP signals pass through the corpus callosum?

[Yujin Han]

Hi, I'm trying to image hippocampal area just underneath the corpus callosum.
But I found out, in that case, recommended lens implantation site would be 'in' the corpus callosum.
So I'm wondering if the GCaMP signals from the ROI can pass through and reach the lens implanted in the corpus callosum without significant loss.

Is there anyone who could give me some advice?

Thanks!

Perhaps you can try prism probe from Inscopix. The focus area for prism probe is at the side of probe tip.
