We developed a new approach for mapping absolute membrane voltage, based on dynamic photocycle control in Voltron2. www.biorxiv.org/content/10.6... Here's my favorite example: human iPSC colonies break into electrical domains as they begin to differentiate.

Wide-area view of membrane voltage in human iPSC colonies.

What's the relation between voltage and calcium in dendrites? Xiang Wu studied this in CA2 hippocampal pyramidal cells in behaving mice. www.biorxiv.org/content/10.6...

What is the computational role of dendritic excitations? Byung Hun Lee and team mapped voltage dynamics throughout the dendritic trees of CA1 pyramidal neurons in mice navigating in virtual reality. www.biorxiv.org/content/10.6...
